Aircraft market in China

Aircraft market in China

The success of the repowering of the A320 in the egg kills short term Chinese ambitions to break the duopoly of Airbus and Boeing in the market moyencourriers aircraft. It allows time to prepare a new aircraft that could enter service in 2030. Latter could be equipped with open-rotor engines that would break new technological leap. Before electric aircraft, it will be the successor to the A320 will allow Airbus to hold off Chinese competition in the market for short and medium-haul aircraft over 150 seats. The Comac Chinese aerospace group is the most dangerous of all the contenders for wanting to break the duopoly of Airbus and Boeing, including bestsellers, A320 and B737, share this lucrative market, which represents over 70% of deliveries aircraft over 100 seats.


End of 2009, Comac C919 launched the program, a single-aisle 150 to 200 seats, whose entry into service is scheduled for late 2016. To nip in the bud the Chinese project that relies heavily Western skills, Airbus decided in late 2010 repower the A320 (A320 Neo). The success of this approach has led Boeing to do the same with the B737 (B737 Max) and pushed the need to launch a new device. The A320neo and 737 Max to enter service in 2015 and 2017, Airbus and Boeing, and have time to prepare for the next move.

Marwan Lahoud, Chief Operating Officer of Airbus Group, Airbus is expected to launch this new device in the middle of the next decade for commissioning in 2030. A new technological leap is expected. It could be caused by dust engine: open rotor, two times larger than today's engines without fairing (which will increase the diameter of the fan and therefore the dilution rate and efficiency propellant), and equipped with two contra-rotating propellers to "open", allowing the aircraft to reach a rate equivalent to that of a device with a conventional turbojet. Especially with its 4 meters in diameter, open rotor could not be placed under the wings. And would be installed vertically at the rear of the plane!

Particularly studied by Snecma as a propulsion options post 2030, open rotor would reduce fuel consumption by 10% compared to the Leap engine, the latest conventional engines CFM scheduled to enter service in 2016 on A320 Neo (in 2017 the B737 Max) with a gain of fuel consumption by 15% compared to current CFM56 engines. Choice or not the open-rotor should be decided between 2017 and 2020.
Noise, feared because of the lack of fairing, should not be a problem insofar as blocking open rotor should display similar to those of Leap engine performance. Which was not acquired there a few years.
However, if they offer the most potential, the open rotor is not the only option of semi-classical architecture, of which the engineers working for the post 2030 period. An engine careened high dilution rate can very well be favored by motorists. Alternatively, the market still prefers to wait to have an engine architecture, this time unconventional
