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 21):
A method of compounding at least two rotary engines, the method comprising:\n drivingly engaging a second stage turbine and a compressor in a turbocharger such as to drive the compressor with the second stage turbine; drivingly engaging each of the at least two rotary engines and a first stage turbine to an output shaft by placing the first stage turbine between two of the at least two rotary engines along the output shaft, the first stage turbine having a lower reaction ratio than that of the second stage turbine; circulating a compressor exhaust flow from an outlet of the compressor into an inlet port of each of the at least two rotary engines; circulating an engine exhaust flow from an exhaust port of each of the at least two rotary engines into an inlet of the first stage turbine; and circulating a first stage turbine exhaust flow from an outlet of the first stage turbine into an inlet of the second stage turbine of the turbocharger.
