A helicopter engine compartment ventilating system includes an ejector nozzle, four air scoops, two air plenums and two air slots. The ejector nozzle encompasses the engine exhaust pipe mouth and downstream flow of exhaust gas for drawing air into, through and out of the engine compartment. Two air scoops are affixed to the helicopter fuselage at the forward perimeter of the engine compartment for supplying air to the two air plenums that direct the air through the engine and transmission oil heat exchangers into the engine compartment. Two additional air scoops are attached to the upper forward perimeter of the engine compartment for supplying air to the upper area of the engine compartment. The air slots are located at the forward edge of each engine compartment door for allowing air to be drawn into the midsection of the engine compartment.
