AIRCRAFT WITH A HYBRID POWER PLANT Russian patent published in 2023 - IPC B64C27/54 

FIELD: aircraft construction.

SUBSTANCE: invention relates to the field of aircraft construction, in particular to the development of cargo, passenger and multi-purpose short takeoff and landing aircraft, providing cargo and passenger transportation, rescue operations, etc. in areas with an underdeveloped airfield network and requiring a transportation shoulder of more than 600…1000 km. The aircraft with a hybrid power plant contains a fuselage, a wing, a power plant, a distributed electrical power plant located on a deflectable flap. The distributed power plant is made in the form of impellers, each of which is placed in a separate air intake attached to the lower part of the deflectable flap, which can be rotated about the rotation axis located downstream from the trailing edge of the wing at a distance of 20-30% of the wing chord.

EFFECT: proposed aircraft provides high aerodynamic characteristics (lift coefficient Su) when interacting with a sustainer power plant in takeoff and landing modes, can significantly reduce emissions of harmful substances into the atmosphere, reduce noise levels, improve operational characteristics and basing conditions (reduction in the length of the take-off, landing, descent and climb distance), can provide a cruising flight speed of up to 760 km/h and a practical range of up to 3000 km.
