ROTARY COMBINED-CYCLE ENGINE Russian patent published in 2025 - IPC F02B53/00 F01C21/00 F01C11/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to power engineering, particularly, to power plants. Proposed engine comprises integrated steam-gas generator (1) of three-stage combustion and rotary machine (2) with two sector vanes in working cylinder. Pneumatic motor (3) consists of two functionally connected rotary machines with two sector blades in working cylinder, where on side of vanes there are inlet (20) and outlet (21) manifolds. Outlet of steam-gas generator (1) is connected to inlet manifold (20) cover, and on the other cover of this manifold (20) there installed is pipeline with heat-resistant ball valve intended for engine start-up. Water treatment unit (4) includes two main elements – recuperator (5) and condenser (6). Capacity of condenser (6) is 10 times less than that of recuperator (5).

EFFECT: longer service life of a combined-cycle engine due to exclusion of formation of scale and reduction of formation of deposits on internal working surfaces and in versatility as to the used fuel without reduction of efficiency in comparison with other types of internal and external combustion engines and without negative effect on the environment.
