VERTICAL TAKE-OFF AND LANDING AIRCRAFT Russian patent published in 2019 - IPC B64C29/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to vertical take-off and landing aircraft. Vertical take-off and landing aircraft comprises fuselage with bottom and tail, prop-fan gas turbine engine for vertical take-off with reduction gear. Fuselage is equipped with front wings on which mid-flight engines are installed. Prop-fan gas turbine engine comprises propfan with two rotor stages, made with possibility of rotation of blades in opposite sides, and connected to it by two shafts birotating compressor and birotating turbine, which are installed inside the internal housing, with formation of the second circuit between external and internal cases. Propfan blades have the possibility of an asymmetric change of angles of attack. Behind the birotating turbine internal and external nozzles with controlled thrust vector are made. Marching motors are connected to reduction gear by power takeoff shafts. Between birotation turbine and internal nozzle of prop-fan gas turbine engine is built-up augmenter.

EFFECT: safe landing at destruction of propeller.
