Abstract
A compound cycle engine (10) comprises a compressor and a turbine section (14, 18), and at least one cycle topping device (16) providing an energy input to the turbine section (18). The compressor section (14) compresses the air according to a pressure ratio PRgt. The cycle topping device (16) further compresses the air according to a volumetric compression ratio Rvc, and wherein PRgt×Rvc are selected, according to one aspect of the invention, to provide a cycle which permit a more compact and lighter compound cycle engine to be provided.
