HIGH-SPEED AIRCRAFT WITH LONG FLIGHT RANGE Russian patent published in 2014 - IPC B64C27/22 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to hybrid aircraft designs. Aircraft (1) contains fuselage (2), rotating lifting plane (10) equipped with two lifting propellers (12) of opposite rotation located in tandem above the mentioned fuselage (2), at least one propulsor (20) and motor group (30). Each propulsor (20) is held by rear fuselage (3). The aircraft (1) includes consolidating system (40) constantly connecting motor group (30) with rotating lifting plane (10), except cases of failure and training. The aircraft (1) contains differential control device (50) for cyclic pitch of lifting propeller blades (12) to control aircraft (1) yawing, and means for inhibition (60) of each propulsor (20). Motor group contains engine-propeller unit including thermal engine and propulsor. Mean of adjustment (70) of lifting propellers rotational speed (Ω) maintains rotational speed of each lifting propeller equal to (Ω1) up to the first air speed (V1) of aircraft (1) and further lowers this rotational speed (Ω) in linear fashion depending on aircraft air speed.

EFFECT: increased speed and range of flight.
