TWIN-ROTOR JET ENGINE Russian patent published in 2024 - IPC F02K5/02 

FIELD: machine building.

SUBSTANCE: invention relates to engine building, namely, to gas turbine jet engines. Particularly for automotive and aviation industry. Invention can be used in development of jet engines, drives of pumps and compressors. Essence of the invention consists in the fact that the energy required for operation of the compressor is taken in the process of expansion of the working medium (combustion products) in the combustion chambers of variable volume formed by the rotors and the housing of the rotors. From the combustion chambers, the working medium enters the nozzle directly. Due to the absence of obstacles to the movement of gases and due to the higher temperature of gases behind the combustion chamber, the outflow rate of the jet stream increases, which leads to an increase in engine thrust. Rotors have radial channels for coolant flow in blades, which enables to achieve high intensity of cooling due to centrifugal coolant flow and makes it possible to increase temperature in combustion chambers and use less heat-resistant materials.

EFFECT: reduced fuel consumption due to increased efficiency and specific power of the engine, reduced cost of production and operation due to possibility to use simpler materials and processes of their processing, increased resource, and reliability of engine.
