AIRCRAFT POWER PLANT Russian patent published in 2020 - IPC B64D27/14 F02K3/77 F02B71/04 F02C5/08 

FIELD: machine building.

SUBSTANCE: invention relates to aircraft engine building, particularly, to aircraft power units of wide-body airplanes with high flight speed. Proposed plant consists of axisymmetric body (1) secured to fuselage central end (2) and central and streamlined plates (3, 4) respectively, comprising two annular shells (5, 6) of main air flow circuit (7) and fuselage boundary layer path (8). Air intake (9), fan (10) and nozzle (11) are installed in channel (8). Annular air intake (12), fan (13) and nozzle (14) are installed in circuit (7). Gas-generating circuit (15) is located behind root parts of fan blades (13) and includes turbo-compressor (16), four-stroke piston gas generators (17), each equipped with two opposite working pistons. Each several pairs of gas generators (17) interact with hydraulic motors (18) and radial shafts (19), gas generators (17) and hydraulic motors (18) are axisymmetrically located on the outer surface of the main air flow circuit (7). Behind fan (13) there are hollow blades (20), through which air from turbo-compressor (16) and hot gas from the piston gas generators (17) is supplied back and forth to turbine (21) and further to nozzle (22). Central shaft (23) of fans (10, 13) of fuselage boundary layer (8) and air main flow (7) and turbine (20) respectively is connected with planetary reduction gear (24) and bevel gear (25) with radial shafts (19) hydraulic engines (18).

EFFECT: technical result achieved by proposed invention consists in increase of aircraft range, flight speed and increase of payload.
