Boeing Commercial Airlines has revealed several design details for 737 Max.
Boeing is developing the Boeing 737 Max, a new family of aircraft, from the Boeing 737 Next Generation family, which it will replace.
The 737 Max will get into service in 2017, with Southwest Airlines as the launch customer.
In an official announcement by Boeing, the company announced the 737 Max design features:
- CFM International LEAP-1B engines will power the aircraft. CFM International, a joint venture company between GE Aviation and Snecma, is developing these powerful and efficient high-bypass turbofan engines.
- The 737 Max family of aircraft will have a 20.3cm (8in) nose gear extension, which will accommodate the larger diameter of the CFM International LEAP-1B engine. The doors will be altered to accommodate the longer nose.
- The aircraft will feature a "electronic bleed air system" which will cut down on fuel burn through anti-icing systems and enhancing cabin pressurization.
- Boeing will control the twinjet’s spoilers using fly-by-wire inputs.
- The 737 Max will have an extended tail cone, and the section of the aircraft above the elevator will be thicker to accommodate the engine.
- The aircraft’s wingtips are also likely to be changed, but no details were provided.
There will be three variants of the 737 Max, namely 737 Max 7, the 737 Max 8 and 737 Max 9, based on the very popular and top selling variants of the 737 Next Generation family: 737-700, −800 and −900ER.
