A compound cycle engine having at least one rotary unit (12) defining an internal combustion engine, a first stage turbine (26) in proximity of each unit (12), and a turbocharger (18) is discussed. The exhaust port of each rotary unit (12) is in fluid communication with the flowpath of the first stage turbine (26) upstream of its rotor. The rotors of the first stage turbine (26) and of each rotary unit drive a common load. The outlet of the compressor (20) of the turbocharger (18) is in fluid communication with the inlet port of each rotary unit (12), and the inlet of the second stage turbine (22) of the turbocharger (18) is in fluid communication with the flowpath of the first stage turbine (26) downstream of its rotor. The first stage turbine (26) has a lower reaction ratio than that of the second stage turbine (22). A method of compounding at least one rotary engine is also discussed. |
