What are the advantages of Boeing 737-800?

Boeing 737-800 belongs to a new generation of Boeing 737 and has the following advantages:

1, design

After rigorous aerodynamic analysis, Boeing redesigned the wing of the new generation 737. The chord length of the wing increased by 50 cm, and the wingspan increased by 5 m, which increased the total wing area by 25% and the fuel capacity by 30%.

The advanced airfoil design makes the maximum range of the new generation 737 reach 6000 kilometers, and it can fly over the continental United States. The cruising speed of the new generation 737 is increased to Mach 0.785 (848 km/h), the maximum speed can reach Mach 0.82 (885 km/h), and the maximum cruising altitude is 12400 m, which exceeds the competing products at the same level.

2. Engine aspect

The engine is the heart of an airplane. Boeing 737-800 chooses CFM56-7 engine as power. This new engine adopts a wide chord fan representing the most advanced technology and a fully authoritative digital engine control system (FADEC).

Compared with the CFM56-3 engine on the traditional 737, the thrust is increased by 1 1%, and the noise is far lower than the third-class noise standard. It also has the characteristics of low fuel consumption and low maintenance cost.

3. Universality.

Boeing 737-800 has the same parts and ground support equipment as the traditional 737, and the same ground maintenance. In addition, the four models of the new generation Boeing 737 have 98% commonality of mechanical parts and 100% commonality of engines, thus bringing satisfactory operating costs to airline users.

4. Flexibility

Boeing 737-800, as the cabin interior of the new generation 737 series aircraft, has also been greatly improved at the request of customers:

The design adopts the design technology of Boeing 777 cabin roof, which greatly improves the flexibility of the aircraft, and the airline can do it in less than 1 minute; Change the cabin layout of the new generation 737 from 5 in business class to 6 in economy class; It is also possible to convert the new generation 737 passenger plane into a cargo plane in less than 1 hour. Boeing 737-800 is an extended model, which can carry 162- 189 passengers.

5. New technology

In February 2000, Boeing began to provide advanced winglet technology as an optional project for 737-800 aircraft. This 2.4-meter-high integrated winglet will make the new generation 737 aircraft have a longer range, increase the payload by about 2.7 tons, reduce fuel consumption and be more environmentally friendly. In May, 200 1, the first 737-800 aircraft with winglets was put into operation at Hapak Lloyd Airlines, Germany.

Extended data

Boeing 737 is known as the most successful civil airliner in the world aviation history. After obtaining the start-up order of 10 aircraft from Lufthansa, the development of Boeing 737 aircraft began in May/964, and the prototype was tested in April/967./kloc-0 obtained the airworthiness certificate in February/968, and/kloc-0 was put into operation in February/968.

The basic model of Boeing 737 is B737- 100. The traditional B737 is divided into 100/200/300/400/500 and1998 65438+February 5th, and the 3000th traditional B737 was delivered. At present, the traditional B737 has been discontinued.

1993165438+10, the new generation Boeing 737 project was officially launched. The new generation Boeing 737 is divided into four models: 600/700/800/900. It has won the favor of the market with its excellent technology and is called the fastest-selling civil airliner. In June 2000, 5438+ 10, Boeing 737 became the first aircraft in history to fly more than 65438+ billion hours.
