Aircraft compound cycle propulsion engine
First Claim
1. An aircraft compound cycle propulsion engine comprising a propulsive fan and a core engine to power said fan, said core engine comprising an air compressor downstream of said fan, at least one rotary internal combustion engine configured to receive compressed air from said air compressor, a power turbine positioned to receive and be powered by the exhaust efflux of said at least one rotary internal combustion engine, a first shaft drivingly interconnecting only said power turbine and said propulsive fan, and a second shaft drivingly interconnecting said at least one rotary internal combustion engine and said air compressor.

Abstract
A ducted fan aircraft compound cycle engine comprises a core engine which includes a compressor, three rotary internal combustion engines fed by the compressor and a power turbine to receive the combustion products of the rotary and combustion engines. The rotary internal combustion engines drive the compressor and the power turbine drives the fan. The engine combines the thermal efficiency of the rotary internal combustion engine with the compact size and light weight of the gas turbine engines.
