VERTICAL TAKE-OFF AND LANDING COMBAT AIRCRAFT Russian patent published in 2020 - IPC B64C29/04 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly, to vertical take-off and landing of an aircraft. Combat aircraft of vertical take-off and landing includes fuselage with bottom and tail, gas turbine engine with reduction gear. Propfan gas turbine engine is installed vertically in the fuselage center of mass, contains a propeller fan with two rotor stages, made with possibility of rotation of blades in opposite sides, and two shafts connected to it, birotating compressor and birotating turbine, installed inside internal housing with formation of the second circuit between external and internal cases. Propeller fan 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. Between birotation turbine and internal nozzle of propfan gas turbine engine is built-up augmenter. Propfan gas turbine engine is connected to auxiliary units by the power take-off shaft.

EFFECT: enabling safe landing at screw destruction.
