CRYOGENIC TURBO-ELECTRIC STOL AIRCRAFT Russian patent published in 2014 - IPC B64D27/24 B64C39/04 B64D35/06 B60L11/02 

FIELD: aviation.

SUBSTANCE: cryogenic turbo-electric STOL aircraft has longitudinal design of triplane with a foreplane, twin-finned H-shape tail unit. The aircraft includes fuselage, wings, wheel landing gear, power plant and variable propulsion system with three different-sized feathering reversible propellers. The foreplane has elevons and panels of all-moving tailplane designed with a capability of differential and inphase turn with reference to the interkeel pitch axis together with propellers from the level attitude downwards and upwards. The power plant, designed using the parallel-serial hybrid technology of the power actuator, is equipped with the left and right electric motors mounted in engine nacelles, gas-turbine engine equipped with forward output shaft for the power take-off to the reduction gearbox of bigger propeller and output shaft for a power take-off, rotationally connected through output and input couplings respectively with the bigger propeller and reversible motor-alternator.

EFFECT: improvement of take-off horizontal thrust/weight ratio and load ratio.
