Celera 500L
The project of the most efficient passenger aircraft Celera 500L with a hydrogen engine is a joint development of Otto Aviation (USA) and ZeroAvia (UK).
The first thing that catches your eye is the unusual shape of the fuselage, but it is it that provides a reduction in drag by almost 60%, thanks to the maximization of the laminar flow (in the laminar flow, the air moves in an orderly straight line parallel to the surface of the hull without vortices — ed. Technical culture), which also gives 80 percent fuel economy compared to the traditional design of the aircraft. Otto Aviation reported the characteristics of the new car: in the presence of an efficient 550-horsepower internal combustion engine, the Celera 500L will be able to fly over a range of 8,400 km with a cruising speed of 740 km/h.

The unique aerodynamic scheme provides a planning range of 22:1, which allows pilots to make a planning flight with the engine turned off at a distance of up to 200 km. It's not hard to guess — such an impressive fuel economy will make flights on the Celera 500L much cheaper (5-7 times) than on a jet plane. Its current six—seat prototype has already made about 60 successful test flights, achieving good results at a speed of 400 km / h and an altitude of more than 4570 m. The partners also hope to create a version with a hydrogen engine, which will significantly reduce the weight of the aircraft and reduce the area occupied by the engine. True, the developer of the ZeroAvia hydrogen plant promises to reduce the range to 1850 km, but it will be a zero-emission aircraft.
