Why is the C919 so much cheaper than the A320 B737 in its class?

The Airbus A320 and Boeing B737-800 are similar, and the A320 is relatively spacious. The B738 carries a bit more people.

1. The maximum number of Airbus A320 passengers shall not exceed 150.

A320 Number of seats: 150 (2 levels) Length: meters: (123), Wingspan: meters, Sweep angle: 25°, Height: meters: (38, 7), Cabin width: meters: (12, 1), Fuselage width: meters: (13).

2. B737-800, (B738) models can carry up to 189 people.

B738 Wingspan (without winglets): m; (with winglets): m. Cabin width: m. The number of seats is 189.

Extended Resources:Model: Boeing 737-800

Wingspan: m (without winglets) m (with winglets).

Cabin width: m.

Number of seats: 164 (two-cabin layout) 189 (single-cabin layout).

Empty weight: tons (91,300 lbs).

Maximum take-off weight: 78245 kg (172500 lb) Max landing weight: 66360 kg (146298 lb) Max glide weight: 174698 lb.

Maximum fuel capacity: 26,025 liters (46,067 lbs).

Cruising speed: Mach (848 kmh).

Maximum speed: Mach (880 km/h).

Maximum range: 3200 nautical miles.

Maximum cruising altitude: 12400 meters.

Take-off field length: 2027 meters.

Length of the landing site: 1327 meters.

Powerplant: two CFM56-7B turbofan engines.

Maximum thrust: 27300 lbs (CFM56-7B27 engine).

The two are actually a class of passenger aircraft, and the passenger capacity is basically between 150-170 people. The data is also easier to remember. The Airbus 320 has a fuselage length of 37 meters and a cabin width of meters; The Boeing 738 fuselage is 39 meters long and the cabin width is meters.

It can be seen that the 738 is 2 meters longer than the 320, which is equivalent to accommodating one or two more rows of seats in practical use, but the cabin width of the 738 is smaller than that of the 320, which means that each seat is slightly more compact than the 320.

I personally understand this, A320 aircraft and 783 aircraft, I feel that the 783 aircraft should be a little larger than the 320, but my answer is not entirely correct, I hope you don't know it in my heart.

China refers to passenger aircraft with more than 150 seats as large passenger aircraft, and the C919 has an all-economy layout of 168 seats, which meets the definition of a large aircraft.

Specialized large aircraft generally refer to transport aircraft with a maximum take-off weight of more than 100 tons, including military large transport aircraft and civil large transport aircraft, as well as military aircraft with a range of 3,000 kilometers or civil passenger aircraft with more than 100 seats.

Geographically speaking, China refers to passenger aircraft with more than 150 seats as large passenger aircraft, while the international shipping system customarily refers to passenger aircraft with more than 300 seats as "large passenger aircraft".

The C919 large passenger aircraft is developed by China in accordance with international civil aviation regulations, with 158-168 seats and a range of 4075-5555 kilometers, which meets the definition of large aircraft, so it can also be called a large aircraft.

July 31, 2014: by China's independent research and development of large jet airliner C919 first aircraft head section in Chengdu off the assembly line, the first aircraft front fuselage, wing and ailerons were previously in Nanchang and Xi'an off the line, other fuselage sections will also be in the near future off the assembly line and delivery, November 10, 2017 at 11:38, domestic large passenger aircraft C919 aircraft 10101 aircraft took off from the 4th runway of Shanghai Pudong Airport, after 2 hours and 24 minutes of flight, At 14:02, it successfully arrived at Xi'an Yanliang Airport and successfully completed the first intercity flight.

1. I think the BAIC 919 is indeed China's new DU generation aircraft, but.

Zhi is not able to compete with Boeing Airbus on the same stage, Biban is actually different from other countries' power assembly lines, engineers, and manufacturing industries. C919 is mainly led by **. Boeing and Airbus are all privately owned. The private sector has to think about quality.

2. Among them, the letter C is the initial letter of the English name "comac" of the commercial aircraft limited liability company of China, which of course represents the meaning of China. The C919, the first 9 has the beautiful meaning of "eternal and enduring and enduring", and the latter 19 represents the maximum capacity of the long-term target aircraft with 190 seats.

3. When it comes to the name of C919, there is another coincidence, we know that the initials of Airbus (Airbus) are A, Boeing (Boeing) initials are B, and the initials of our domestic large aircraft are C, which is exactly the order of ABC.

The C919 and Boeing 737 are not much different from the Airbus 320.
