A compound engine assembly with at least one rotary internal combustion engine, an impulse turbine, and an exhaust pipe for each internal combustion engine providing fluid communication between the exhaust port of the respective internal combustion engine and the flow path of the turbine. Each exhaust pipe terminates in a nozzle. For each exhaust pipe, a ratio Vp/Vd between the pipe volume Vp and the displacement volume Vd of the respective internal combustion engine is at most 1.5. A minimum value of a cross-sectional area of each exhaust pipe is define...
1. A compound engine assembly comprising: an engine core including at least one internal combustion engine defining an internal cavity and including a rotor sealingly and rotationally received within the internal cavity to provide rotating chambers of variable volume in the internal cavity, the variable volume varying between a minimum volume and a maximum volume with a difference between the maximum and minimum volumes defining a displacement volume Vd;a turbine configured as an impulse turbine having a pressure based reaction ratio of at most 0.25, the...
