HYBRID TURBOFAN PLANT WITH BUILT-IN ROTOR ICE Russian patent published in 2020 - IPC F01C1/22 F01C11/00 F02C5/06 F02B53/04 

FIELD: engine building.

SUBSTANCE: invention relates to engine building, particularly, to highly efficient and environmentally friendly combined gas turbine units (turbofan plants). Hybrid turbofan plant with built-in rotor ICE comprises turbofan engine with high-pressure system with high-pressure generator and low-pressure system. High pressure exciter is at least two modules of rotary internal combustion engine, comprising at least three identical working sections in module, each of which includes identical gas generator and identical rotary actuating unit, communicating with cavities by means of common input-output channel, wherein rotary actuating units comprise common power takeoff shaft, wherein the rotary actuating unit is a planar rotor with an eccentric arrangement of the rotor and a crescent inner cavity, having a housing which limits an expansion chamber, the volume of which is always known to be greater than the volume of the combustion chamber.

EFFECT: technical result consists in simplification of design due to exclusion of reduction gear, reduction of weight and size characteristics and considerable improvement of characteristics of standard gas turbine engine.
