Abstract:
A compound cycle engine having an output shaft; at least two rotary units each defining an internal combustion engine, a first stage turbine, and a turbocharger is discussed. The first stage turbine includes a rotor in driving engagement with the output shaft between two of the rotary units. The exhaust port of each rotary unit is in fluid communication with the flowpath of the first stage turbine upstream of its rotor. The outlet of the compressor of the turbocharger is in fluid communication with the inlet port of each rotary unit. The inlet of the second stage turbine of the turbocharger is in fluid communication with the flowpath of the first stage turbine downstream of its rotor. The first stage turbine has a lower reaction ratio than that of the second stage turbine. A method of compounding at least two rotary engines is also discussed.

Claim (Index 11):
A compound cycle engine comprising:\n a first stage turbine having a first turbine rotor drivingly engaged to an output shaft; at least two rotary engines each having an engine rotor sealingly and rotationally received within a respective housing having an inlet port and an exhaust port, the engine rotor of each of the at least two rotary engines being drivingly engaged to the output shaft, the at least two rotary engines including a first rotary engine located in front of the first stage turbine along the output shaft and a second rotary engine located behind the first stage turbine along the output shaft; a respective exhaust pipe providing fluid communication between each exhaust port and an inlet of the first stage turbine; a turbocharger including a compressor and a second stage turbine drivingly engaged to one another; an inlet duct providing fluid communication between an outlet of the compressor and the inlet port of each of the at least two rotary engines; and a turbine pipe providing fluid communication between an outlet of the first stage turbine and an inlet of the second stage turbine; wherein the first stage turbine has a lower reaction ratio than that of the second stage turbine.
