VERTICAL TAKE-OFF AND LANDING AIRCRAFT Russian patent published in 2019 - IPC B64C29/04 

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, propeller fan gas turbine engine installed vertically, containing propeller and connected to it two shafts birotating compressor and birotating turbine, which are installed inside, internal housing, with formation of the second circuit between external and internal housing. Behind the birotating turbine there is an internal nozzle with an adjustable thrust vector and an external nozzle. Between birotating turbine and internal nozzle of fan-assisted gas turbine engine is built-up augmenter. Propeller fan is made of two rotor stages with possibility of their rotation in the opposite direction. At the tail end or on the front wings the sustainer engines are installed. On the fuselage bottom there is a safety platform having a vertical hole for the outer nozzle of the double-flow gas turbine engine, the inner cavity of the safety platform is filled with a damping material.

EFFECT: possibility of safe landing of aircraft with destruction of propeller fan.
