In an aircraft having a cowled air‐cooled engine arranged behind the airscrew with its crankshaft longitudinally of the aircraft and a passage in the. interior of a wing which merges into the cowling, the whole of the cooling air which has passed through the cowling is transmitted to an outlet adjacent the trailing edge of the wing. An engine 11 is mounted on a wing 12 and is surrounded by an annular cowling 13 which is faired into the wing and its rear end is connected to an outlet opening 14 provided in the trailing edge of the wing and controlled by a pivoted flap 15 which may constitute an air‐brake. In a modification, the rear end of the cowling is directly connected to the leading edges of the wings, the air being discharged between the trailing edge of the wing and the ailerons 18. In a still further modification, a fifteen‐cylinder engine of star form with the cylinders arranged in lines of three is housed in the wing 12, the air‐inlet being through horizontal slots. Internal baffles are provided.
