A compound engine assembly including a compressor 14, an engine core 12 including at least one rotary internal combustion engine and having an inlet in fluid communication with an outlet of the compressor, a turbine section 18 having an inlet in fluid communication with an outlet of the engine core and configured to compound power with the engine core, and an air conduit 70 having at least one heat exchanger extending thereacross. An outer wall 94 of the air conduit has a plurality of openings 96 defined therethrough downstream of the heat exchanger(s), each selectively closable by a pivotable flap movable between a retracted position where the opening is obstructed and an extended position away from the opening. Each opening defines a fluid communication between the air conduit and the ambient air when the respective flap is in the extended position. A method of directing flow through a compound engine assembly is also discussed.
