LONG-HAUL AIRCRAFT WITH HYBRID POWER PLANT Russian patent published in 2025 - IPC B64D33/02 B64C3/28 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering and can be used in designing advanced civil mainline aircraft. Proposed aircraft comprises two engine nacelles and two power plant engines mounted on top of wing rear, and fin with T-like empennage. Aircraft is equipped with hybrid power plant consisting of bypass turbojet engines and impeller-type electric jet engines. Each bypass turbojet engine is installed in a nacelle located in the area of the wing with the fuselage joint in such a way that the nacelle inner and outer surfaces, including the air intake channel, are smoothly interfaced with the wing and fuselage surfaces, Every electric jet engine is of impeller type, its air intake channels and nozzles are located in wings under engine nacelles. Wherein surface of every wing changing into turbofan engine air intake channel bottom surface is provided with perforation to feed air into impeller-type jet engine air intake channel.

EFFECT: described measures ensure the noise reduction on the terrain and the engines protection against ingress of foreign objects due to their location above the wing, reduced external resistance due to reduced washed surface of aircraft due to absence of pylons of engine nacelles, gas-dynamic stability of power plant operation due to air bleeding from boundary layer region into jet engine air intake.
