COMPOUND ENGINE ASSEMBLY WITH COMMON INLET
First Claim
1. A compound engine assembly comprising:
- an air conduit having an inlet in fluid communication with ambient air around the compound engine assembly;
a compressor having an inlet in fluid communication with the air conduit;
an engine core including at least one internal combustion engine each having a rotor sealingly and rotationally received within a respective internal cavity to provide rotating chambers of variable volume in the respective internal cavity, the engine core having an inlet in fluid communication with an outlet of the compressor;
a turbine section having an inlet in fluid communication with an outlet of the engine core, the turbine section configured to compound power with the engine core; and
at least one heat exchanger in fluid communication with the air conduit, each of the at least one heat exchanger configured to circulate a fluid of the engine assembly in heat exchange relationship with an airflow from the air conduit circulating therethrough.

Abstract
A compound engine assembly including an air conduit having an inlet in fluid communication with ambient air around the compound engine assembly, a compressor having an inlet in fluid communication with the air conduit, an engine core including at least one rotary internal combustion engine and having an inlet in fluid communication with an outlet of the compressor, a turbine section having an inlet in fluid communication with an outlet of the engine core and configured to compound power with the engine core; and at least one heat exchanger in fluid communication with the air conduit, each heat exchanger configured to circulate a fluid of the engine assembly in heat exchange relationship with an airflow from the air conduit circulating therethrough. A method of supplying air to a compound engine assembly is also discussed.

17. A method of supplying air to a compound engine assembly, the method comprising:
-
directing ambient air from outside of the compound engine assembly into the compound engine assembly through an inlet of an air conduit; directing the air from the air conduit through at least one heat exchanger to cool a fluid of the compound engine assembly and from the air conduit to an inlet of a compressor of the compound engine assembly; and directing compressed air from the compressor into an engine core of the compound engine assembly, the engine core including at least one rotary internal combustion engine creating an exhaust flow driving a turbine section of the compound engine assembly and compounding power with the turbine section to drive rotation of a common load. - View Dependent Claims (18, 19, 20)
