The Boeing 747 program started in 1966. And in January 1970, the first aircraft began to arrive to commercial airlines. When designing a new aircraft, Boeing had to build a new construction hangar near Seattle so that the first model, the Boeing 747-100, could fit there.

-100, -200 and -300 series

The first modification, 747-100, has a length of about 70 meters and a height of 20 meters with a wingspan of 60 meters. Its weight was 162 tons. In order to cover a flight distance of about ten thousand kilometers, special engines were developed for it by Pratt and Whitney. Later, engines from General Electric and Rolls Royce began to be used. The 100th version includes an improved 747-100B model, as well as a short-range variant with a passenger capacity of up to 550 people - the 747-100SR (Short Range), designed specifically for short flights between the Japanese islands.

The “200th” series received a higher initial weight and a longer flight range. In the 747-200B version it is 10,800 kilometers. An undoubted advantage was the ability to easily adapt passenger aircraft into cargo (747-200F), as well as combined (747-200C, 747-200M). And the -200C variant has undergone further improvements in terms of cargo transportation. One of these improvements was the folding nose. In 1983, the Boeing 747-300 took to the skies. Ego's main characteristics have been increased. The flight range was now 12,300 kilometers. The upper deck was expanded. And consequently the number of passenger seats has increased. The series also includes cargo-passenger variants - 747-300M and 747-300SR, intended, like the -200SR, for domestic flights in Japan.

The most successful versions of the 747-400 and the new 747-8

The 747-400 boasts of being Boeing's best-selling aircraft. It was put into operation in 1989. Compared to the 747-300, it has an improved wing, more powerful engines, and improved interior quality. The 747-400 reaches a maximum flight range of 13.5 thousand kilometers without stopping for refueling and can fly at speeds of up to 913 kilometers per hour. The decks of the “four hundredth” can accommodate up to 524 passengers. A cargo version of the airliner was also released, model 747-400F, combined, model 747-400M, for short flights - 747-400D and version 747-400ER for longer flights. Production of the Boeing 747-400 ended in December 2009, with the introduction of the new Boeing 747-8, which first flew in February 2010. Two versions of the aircraft are presented, the passenger 747-8I and the cargo 747-8F. Both models feature new, energy-efficient GE engines for improved fuel efficiency and reduced emissions.

The modified Boeing 747 of the American president is capable of speeds of up to 1000 km per hour. Thanks to its excellent technical characteristics, it is called the “plane of the Apocalypse”.

The Boeing 747 400 is a double-deck jet passenger aircraft designed to carry more than 500 passengers. This modification of the Boeing can fly over a distance of up to 14 thousand kilometers. Today, air transportation on this airliner is carried out by Rossiya Airlines.

History of the aircraft

This modification of Boeing was created on the basis of the Boeing 747 300. In the mid-80s, the 300th modification of Boeing did not allow the full capabilities of Boeing Airplanes to be realized. In view of this, it was decided to create a new modification of the airliner, which will be characterized by increased fuel economy, longer flight range, improved interior and a 10% reduction in operating costs. The development of the new vessel began back in 1985, and the first rollout of the 400th took place in January 1988. By that time, about 100 orders for the production of the Boeing 400 had been received.

The first official flight of the new vessel took place on April 29, 1988. The new modification of the B747 remained in flight for more than 2 hours. Test pilot James Lesh and his crew were pleased with the test results, which allowed the vessel to receive an airworthiness certificate. On January 26, 1989, the first 400 was delivered to Northwest Airlines. And just 2 weeks later the first passenger flight of this airliner took place on the Minneapolis-Phoenix route.

Cabin configuration

The cabin layout of the Boeing 747 400 of Rossiya Airlines provides for the division of seats into 2 categories: economy and business. In economy class, the distance between the seats is no more than 90 cm. At the same time, the seats recline only 60 degrees. For the convenience of economy class passengers, each seat has a folding table.

Thanks to the special design of the seats in business class, they can be transformed into an almost full-fledged bed. The advantage of this is also considered to be a greater distance between the seats. Another plus is a special menu for passengers, free drinks and access to Wi-Fi.

The main feature of this liner is its division into lower and upper decks. The standard number of seats on the lower tier is 470. This deck is designed exclusively for economy class passengers. The basic configuration of the seats is 3:4:3. However, there are exceptions. For example, the rear of the ship uses a 2:4:2 layout, and the bow uses a 2:3:2 layout.

Important! There are 3 blocks of bathrooms on the lower deck: in the tail, between the 20th and 22nd lines, and also at the 43-44th rows. The Boeing 747 400 also has dressing rooms (rows 54-59) and catering units (rows 31-34). The descent from the upper deck is located near row 31.

The upper deck of the liner is represented by both business and economy class. Business class seats are located from the first to the third line. Starting from the 5th row, the “increased economy class” begins. The upper tier is located in the nose of the aircraft. For the convenience of passengers on the upper tier, there are 2 bathroom blocks. The capacity of the standard upper deck is 41 seats (business - 12 and economy - 29).

You should know! There are 3 main schemes for the Boeing 747 400 of Rossiya Airlines. The EI-XLM scheme differs significantly from the standard version. In accordance with this layout, passengers can occupy Super Space category seats on the lower tier of the aircraft. These are economy class seats with improved characteristics. They are located in the bow of the lower deck. At the same time, in EI-XLM the entire upper deck is represented exclusively by business class seats.

Choosing the best seat on the plane

The best seats on the Boeing 400 are considered to be rows 1-3 of the upper tier. This is where business class is located with comfortable seats and 15.4-inch monitors. The distance between lines in this class is more than one and a half meters. The seats on the 5th line of the upper deck are distinguished by increased convenience. Even though they are economy class, passengers occupying these seats will have plenty of legroom. In addition, increased comfort for upper tier passengers is provided by the presence of 8.9-inch displays.

On the lower deck, the most comfortable seats are considered to be seats from the 10th to the 12th line. The comfort of these seats is due to the fact that the seats are installed in pairs - 2 chairs are more comfortable than 3 or 4. These seats are intended for passengers with children. This is where the mounts for baby bassinets are installed.

You should know! On the lower deck, the seat count starts from line 10.

The layout of the lower deck allows us to consider the best seats of this vessel to be seats E and F in rows 17-19. Paired seating is also used in these seats. You can also note 31 lines, which are characterized by a lot of free space. However, it is due to the fact that there is a bathroom nearby. In addition, seat 31C is located directly next to the stairs from the upper tier.

In the EI-XLM modification, the best seats include lines 1 to 4. This is where the Super Space category seats are located.

Bad places: how not to make a mistake

It's no secret that the double-decker Boeing 747 400 has several bad seats that can significantly ruin the flight experience. First of all, it is worth noting the places in line 29. In this row, the seat backs do not recline due to the proximity to the emergency exit and the bathroom. The same goes for the 19th line. Seats A, D, E and L do not recline. The remaining seats in this row, although postponed, have significant limitations.

Holders of tickets for seat C on lines 32-34 will feel significant discomfort due to the constant movement of other passengers. This is due to the fact that these seats are located in close proximity to the stairs leading to the second floor. Passengers traveling in seats in rows 43, 54, 70 and 71 will not have the best flight experience. Due to the close proximity of emergency exits, the seats in these places cannot be transformed. When studying the location of seats on this plane, it is also worth noting that the rows located near the bathrooms (20-22, 27-29, 41-46 and 69-71 rows) will not be the best option.

On the upper deck, it would be a mistake to buy tickets in the last row. The main disadvantage of this line is the proximity of the toilet. In addition, there is a staircase to the lower deck nearby.

Before purchasing a ticket for a flight operated by Boeing 747 400, passengers should pay attention to several very important nuances:

You should not buy tickets for seats located close to service areas. There are always queues here, which creates discomfort and unnecessary noise.
If you are planning a long flight, you should not buy tickets for seats that do not have reclining seats.
Passengers with small children should buy tickets to the front of the plane. But for those who do not want to hear children’s crying and noise, on the contrary, it is not recommended to purchase tickets in this part of the ship.
For afternoon and morning flights, it is worth buying tickets for seats near the window.
Seats D and G, located in the middle of the cabin, are uncomfortable due to the constant movement of passengers and flight attendants.

The brainchild of the American aircraft manufacturing giant, Boeing, the 747 model came to the market back in 1970. Then the need for a new aircraft was so high that it was created very quickly, in just 4 years, from drawings to the last tests. Initially, these aircraft were made with an eye to converting them into cargo aircraft, since it was believed that civil aviation would soon embark on supersonic transport.

But this did not happen, and the Boeing 747-100 (the first mass modifications), thanks to its amazing combination of high speed, efficiency and capacity, firmly occupied the niche of long-distance civil air transportation in many countries of the world.

History of creation

In the mid-twentieth century, the popularity of air travel grew rapidly. Every year the demand for civil aviation aircraft increased exponentially. This trend, as expected, led to the emergence of an air carrier crisis. The existing capabilities of aircraft at that time in terms of the amount of cargo and people transported required rapid growth.

This is how the story of the creation of the huge Boeing 747 airliner began. By the way, when it just started entering the market, almost all newspaper reviews about it were replete with superlatives - such a large aircraft turned out to be, far ahead of its time.

The father of the Boeing 747 is considered to be an engineer named Joe Sutter.

He was already working closely on the previous one when he was entrusted with the project of a new capacious civilian airliner.

The developer took as a basis the idea of a transport aircraft, work on which was carried out several years earlier, when the Boeing company lost in the competition for a large military order in the United States. Therefore, the aircraft was initially designed as a completely double-deck aircraft.

But later, according to numerous recommendations from air carriers, the upper deck was reduced and began to occupy only part of the fuselage. This gave the Boeing its famous “humpbacked” shape, due to the two decks located on top of each other in the bow. The pilot's cabin is located on the upper tier.

These manipulations with the aircraft design were not carried out by chance. The developers seriously believed that the era of supersonic airliners was approaching and measured out a short lifespan for the new 747 Boeing. In the future, the released models were supposed to be converted for cargo needs, so they placed the cabin at a height in order to arrange a cargo compartment under it.

Air carriers did not immediately like the Boeing 747.

Many did not believe that it would be a cost-effective civilian airliner. And the plane did have problems, as it burned more fuel (with 4 engines) than most competitors with 3 engines. But Boeing also accommodated more passengers on board.

Therefore, after improvements and modifications, the 747 models became more popular and gradually began to occupy their niche in the air transportation market.

Design

The main distinguishing feature of the Boeing 747 is the characteristic hump in the nose. As already mentioned, initially the plane was supposed to be made completely double-decker. But this idea was abandoned and the upper floor was reduced. Today it makes up 35% of the length of the entire fuselage.

Fuel tanks are provided in the wing, in addition, they are also in the tail to maintain the weight balance of the aircraft.

The wing configuration is low-wing, the wing itself is swept-back. The plumage is single-finned. The first versions of Boeing received developed wing mechanization. The models use three-slot Fowler flaps.

Their main purpose is to reduce speed when landing on short runways. This was done due to considerations of poor airport infrastructure in the past. Today, most air harbors are able to accommodate Boeing 747 series without any problems.

Upper tier

The upper deck in front has a pilot's cabin and passenger seats behind it. The number of passengers transported on the second tier can reach 50 people. There are models (less spacious) where only business class seats are located behind the cockpit.

The most common version in Russia is 3 rows for business passengers and another 9 rows of luxury seats.

The most spacious Boeing 747 (up to 660 people) have the second tier completely dedicated to economy seats. There is one passage between the seats, the seats are arranged in a “2-2” pattern.

Lower tier

The lower deck is completely dedicated to the passenger lounge. The seats are arranged according to the “3-4-3” pattern. There are two aisles between the rows of seats. In general, two aisles are a distinctive feature of wide-body airliners.

The tier below is typically either seated in economy class or partially filled with high-level “comfort” seats.

Flight performance compared to competitors

The Boeing 747 is considered the longest civilian airliner in the world. The latest model - 747-8 - reaches 76 meters (previous versions were produced at 70.5 meters).
The keel height remains the same for all modifications of the 747 series and does not exceed 19.5 meters. The width of the aircraft is 68.5 meters, and the wing area is 554 square meters.

The difference between Boeings is their take-off weight, which reaches 442 tons.

This is understandable: the aircraft was originally planned as a cargo plane, and this trend is still maintained by engineers.

On takeoff, the plane accelerates to 270 kilometers per hour before lifting off the ground. The ceiling of the aircraft is 13,750 meters. In terms of cruising speed, Boeing 747s are also ahead of their competitors in the subsonic niche (913-918 km/h, maximum – 988 km/h). For reference: the speed of sound in air is 1224 km/h.

High reliability of the aircraft is achieved by installing 4 engines on the wing.

Boeing 747s are economical. Compared to competitors, fuel consumption is up to 3.5% less with a long flight range of more than 14,000 kilometers without landing. Boeing 747s are considered long-haul airliners.

Modifications

Boeing 747-100 - the life of double-decker Boeings began with this model. They accommodated from 366 to 452 passengers on board (depending on the amenities provided: the lower the maximum capacity, the more luxury seats). The flight range reached 9,500 kilometers, and the model was produced from 1968 to 1976, when the oil crisis began.
The Boeing 747-100SP is an optimized version of the previous model. Its main differences are an increased range of non-stop flights, more economical engines, a reduction in the length of the fuselage and, as a result, capacity - no more than 220 people.
Boeing 747-200 is a successful development of the Boeing company, known for its versatility. The 200 models were produced exclusively for passenger transportation, for transporting cargo, as well as in combined versions (747-200M Combi). The model range received even more powerful engines, a maximum permissible take-off weight (up to 380 tons), as well as a high range (up to 12,690 kilometers).
The Boeing 747-300 was initially produced with three engines, but due to low demand they were abandoned and the classic 4-engine version was released in 1980. The main difference is the increased area of the upper deck, which made it possible to take more passengers on board (up to 624 with only economy class seats fully installed on the entire liner).
Boeing 747-400 is perhaps the most popular modification of the Boeing 747. Their external difference is vertical wing winglets to reduce the inductive drag of the wing, which reduces fuel consumption. By the way, on the Japanese islands there are still versions that do not have this distinctive feature due to short flight distances. The 747-400 crew has been reduced to two people (having removed the flight engineer), and the most modern avionics are being installed on board.
Boeing 747-8 is the latest modification of the famous double-deck aircraft. Engineers managed to increase the weight on takeoff, as well as increase the capacity indicators. The last tests ended in 2010, and since 2011 the models have been supplied to airlines around the world.

At the time of its release, the Boeing 747 became the first wide-body civilian airliner and, in fact, opened a new page in passenger air transportation. For 36 long years (before the advent of the aircraft), the American aircraft held the palm in terms of the maximum number of seats for passengers.
Since the airliner’s production deadlines were extremely tight, the first representative of the 747 model series was assembled in the open air. Only later was the world's largest building in terms of volume built for the production line (13.3 million cubic meters of covered space). And the area is also quite large - more than 50 hectares (70 football fields). To set up production, the Boeing company took out a loan of $2 billion, which was an unprecedented amount at that time.
Today, a large number of modifications of the Boeing 747 are known. They are used both for transporting passengers and for transport purposes and special tasks. Thus, the Evergreen 747 Supertanker model is known as the largest firefighting aircraft on the planet. He takes on board almost 76 thousand liters of chemical mixtures to extinguish the fire.
Another feature is the structure of the wing. The 747 has a 37.5-degree sweep, which is greater than other competing airliners. To get rid of dangerous wing vibrations in flight, depleted uranium is used as cargo in construction.
The US President flies on an improved Boeing 747, nicknamed in the press “the plane of the Apocalypse.” The first board of the country is capable of reaching speeds of up to 1000 kilometers per hour.

Aircraft prospects

The main development of the 747 Boeing received in the 747-8 models. These are the latest aircraft that receive technological filling. Also, traditionally, the new generation of Boeings has become more economical, quieter and less harmful to the environment. The company's main prospects for the development of civil aviation are related to these models.

The versatility of the new airliner has been a big help: its controls are very similar to the 747-400, the legendary model. This means that only minor pilot retraining is required.

When building the 747-8 model, carbon fiber is used to reduce the weight of the aircraft.

But, all the same, this Boeing became the heaviest aircraft (take-off weight of the Boeing 747-8 aircraft is 442 tons) in the history of US military and civil aviation.

Externally, the differences between the latest model are not very large. The fuselage was lengthened by more than 5 meters, compared to the 747-400. By the way, this allowed the new Boeing to become the longest airliner in the world: it beat the previous leader (Airbus A340-600) by almost a meter.

The main difference is a fundamentally new wing structure. Using the same geometry, it became thinner and wider. The console ends are different from those installed on the 747-400. They are closer to .

Working with the wing made it possible to increase the capacity of the tanks located in them. And various technical indicators led to significant fuel savings. Thus, the aerodynamic properties of the wing profile make it possible to avoid tip vortices and reduce wake and drag.

Conclusion

The Boeing 747 was initially built for a short period of time to “close” the growing demand for air travel, to become a transitional stage in the era of supersonic civil aviation.

But some unique features characteristic of these American liners, on the contrary, gave it a long service life.

High efficiency, reliability, and versatility have allowed the Boeing 747 series to firmly occupy the niche of civil air transportation and remain there to this day. It is likely that the model range will serve people for a very long time, requiring only minor improvements and innovations.

Tourists who often fly on long-haul routes leave numerous reviews about the Boeing 747-200. This aircraft has been successfully used on Russian airlines for a long time. Designed for long-distance flights, it flies to the Far East. Also used on many overseas routes. Aeroflot, Transaero and other airlines are successfully using this not entirely new Boeing model. Its production ended in 1991, but many cars are still in excellent condition. Many passengers, given the opportunity to choose, prefer these aircraft.

It should be noted that passenger reviews of the Boeing 747-200 airliner are the most contradictory. Most often this is not due to the make of the car, but to its age. Considering that the first Boeing 474-200 began operating in the early 70s, then many of them have quite a long service record. Some of the vehicles began to be used for freight transportation, but those that are used have undergone major overhauls and are now not inferior to younger models.

— 12 wide folding sleep chairs

— 2 rows — for each passenger individual monitors for viewing video programs, an individual control panel for audio and video programs, an expanded range of drinks, two hot meals a day, blankets and pillows for each passenger, an amenity kit.

Lower deck:
Business class is the most comfortable and convenient cabin on the lower deck:
16 wide chairs
2 rows - for each passenger individual monitors for viewing video programs, an individual control panel for audio and video programs, a footrest under the seat, an expanded range of drinks, two hot meals, blankets and pillows for each passenger, an amenity kit.

Also, on the lower deck there is an economy class:

440 seats
3 rows
4 seats in the middle row, 3 seats in the outer rows, next to the windows, for each passenger individual monitors for viewing video programs on the backs of the seats in front, individual control panel for audio and video programs, soft and alcoholic drinks, two hot meals a day, amenity kit .

The total number of passengers in a three-class cabin is 366 people, in a two-class cabin - 452. The maximum number of passengers is 490, plus 3 crew members.

Flight characteristics of Boeing 747-200:

— cruising at an altitude of 10,600 m — 895 (0.84) km/h
— maximum — 942 km/h
— vertical ceiling, m — 13,720
— flight range, km with maximum fuel reserve — 12,150 (12,700)
— flight range with 452 passengers and luggage (with fuel reserves) — 10,670 km.

Dimensions and mass indicators of the aircraft:
— aircraft length, m — 70.66
— wingspan, m — 59.64
— aircraft height, m — 19.33
— fuselage diameter, m — 6.5
— wing area, m2 — 510.9

The takeoff weight of the Boeing 747-200 reaches about 374,850 kg, and the landing weight is 285,700 kg. The empty weight of the aircraft is 169,700 kg, without fuel - 238,800. Payload - 69.1 tons. Typical fuel capacity - 199,158 liters, maximum - 204,360 liters. This model also has 5 cargo pallets, 14 LD-1 containers, weighing 155.6 kg.

The best seats in the Boeing 747-200 cabin, in my opinion of experts, are located in the rear of the plane, as well as the first rows from the emergency exits - No. 31B, No. 31C, No. 31D.

Some passengers notice some trembling in the upholstery when landing. But this is not observed on all flights. Obviously, the technical condition of the machines has an effect. When studying passengers' opinions about the Boeing 474-200, the first thing you notice is the difference in the description of the cabins. Some talk about spacious places, others about cramped spaces. It all depends on the carrier company and the requirements they place on the cabin equipment. To avoid getting into an awkward position, it is advisable to inquire before purchasing tickets how many passengers the plane can take on board. The higher the number, the more cramped the interior will be. This is the pattern.

In the seventies of the last century, Boeing engineers presented the world with an innovative development - the first wide-body airliner of the 747 series. The model quickly gained popularity among carriers. In addition, until 2005, these aircraft were leaders in the category of the largest aircraft. Let's look at the characteristics of the Boeing 747 in detail to understand why the invention so captivated aviators.

The aviation industry flourished in the sixties of the twentieth century. At this time, leading US designers set out to create large-sized transport for transporting 400–500 people. After all, the high demand for air tickets in those years caused a shortage of new generation aircraft. Engineers developed a design for the vessel based on the previous model, the Boeing 737. Moreover, the aviators’ first idea was to create a cargo-passenger airliner.

Such extraordinary thinking of the developers explained the appearance of the first modifications of supersonic passenger airliners. Scientists assumed that this series would not be able to compete with high-speed aircraft in the near future, and provided a backup option. This solution determines the design and some technical characteristics of the Boeing 747 400.

The crew cabin is on the upper deck here, since the plans planned to allocate the lower sector for cargo transportation. And the maximum take-off weight of the first sample board of 370 tons spoke about the potential of using such vessels for cargo transportation.

The project was gradually refined and modernized. By 1976, aviators abandoned the idea of making the fuselage of the airliner into two full decks and settled on proposing a modern type of modification with a “hump.” Here the upper compartment accommodates the cockpit and up to 50 passenger seats. In terms of people transport potential, the capacity of the Boeing 747 400 is amazing. The plane lifts up to 660 passengers into the air, which was considered a world record before the advent of the Airbus A380.

Initially, 25 units of the 747 100 series were produced. Subsequently, the company periodically modernized the invention, changing the wingspan and the design with the position of the landing gear. In addition, over the history of production of ships of this class, the volume increased by 16% and amounted to 442 tons on board the 747-8. Today this large-scale project is closed, but airlines use such equipment on transcontinental flights.

The first experimental flight of the new series took place in 1970 of the twentieth century. It is noteworthy that the largest fleet of these aircraft was on the balance sheet of Japan Airlines. However, today this carrier has completely abandoned such ships.

An interesting fact in the history of aircraft development was the fuel crisis, as a result of which the use of such giants temporarily brought losses. Even to produce the planned number of first models, the designers took out loans, since the company did not have such a significant amount. True, over time, the costs paid off in full and tripled the funds spent on development.

Advantages of the vessel design

Now let's talk about the merits of the series. The appearance of such aircraft became a new word in the field of aviation - after all, before Boeing there were no wide-body models. The board is equipped with four powerful jet engines, which has a positive effect on the flight range. The cruising speed of a Boeing 747 passenger aircraft in flight is 910–950 km/h.

In addition, the aircraft flies a distance of 14,205 kilometers without refueling. Moreover, these indicators apply to a loaded airliner. The passenger capacity of the Boeing 747 is up to 660 people. In addition, the ship can accommodate luggage, two pilots, a flight engineer and flight attendants. It’s not for nothing that the model is called the “Jumbo Jet” or the king of the skies - before the advent of Airbus, this series of aircraft was the leader in the category of passenger transportation.

The aircraft's aerodynamic performance surpassed the previous series - 737. Here the wings were highly modernized - with a wing height of 6 meters and a wingspan of 60 meters, engineers achieved fuel savings of 3.5% and an increase in flight duration.

The Boeing 747 was the first wide-body airliner and remained the largest passenger aircraft for 35 years.
