METHOD OF OPERATING AIRCRAFT POWER PLANT Russian patent published in 2024 - IPC F02K3/06 B64U50/00 

Abstract RU 2827275 C1

FIELD: aircraft engine building.

SUBSTANCE: invention can be used, for example, for an unmanned aerial vehicle. Connecting rod 3 of the additional engine through crank 1 drives shaft 2 with propeller 11 (creating the thrust force from the discharged air) and through freewheel clutch 12—compressor 13, forcing air 14 into combustion chamber 17, into which fuel is simultaneously injected through nozzles 16 and ignited with plug 15 obtained combustible mixture. Combustion products are fed through turbine 18 into nozzle 19 and flow therefrom, creating a reactive thrust force. Turbine (compressor) rpm will increase and after propeller rpm is exceeded, clutch disengages. As a result, the propeller will continue to rotate from the additional engine at a relatively low frequency, and the turbine—at a high frequency. At the same time independent control of both engines is possible.

EFFECT: simpler design, higher reliability and improved performance.
