Passenger planes doubling by 2036 and a key plane will be the Boeing 797

The number of passenger and cargo planes will nearly double over the next 20 years. One of the key planes will be the new Boeing 797.
The Boeing 797 is expected to be a new airplane releasing from 2024-2027. Boeing calls it the new midsize airplane (NMA). The NMA is to be a twin-aisle plane with a capacity for 220 to 270 passengers and a range of 5,200 nautical miles. The new airliner would fill a gap between the narrow-body 737 MAX and wide-body 787 Dreamliner, which have ranges as high as 3,800 nmi and over 8,000 nmi. The design work should be done by 2020.
Asia is forecast to be the biggest travel market in the world, growing at 5.7 percent annually, and by 2036 passenger traffic throughout Asia will constitute nearly 40 percent of global passenger traffic.


For the new aircraft’s engines, Boeing is looking for a geared turbofan. Geared turbofans are aircraft engines that achieve greater efficiency by placing a gearbox in between the fan and the turbine assembly so they can rotate at different velocities. The versatility provides greater optimization of engine speed during different parts of flight.
