Title: Improvements in and relating to aircraft engines
IPC: B64D33/10
Filed: 1935-08-07
Abstract: 460,975. Aircraft engine installation. BAYNES, L. E. Aug. 7, 1935, No. 22340. [Class 4] In a cooling system for aircraft engines, the appropriate part of an air-cooled engine or the radiator of a liquid cooled engine is positioned within a wing and is cooled by air passing through an inlet aperture in the under surface of the wing adjacent the part to be cooled and exhausted through a rearwardly facing outlet in the trailing edge of the wing immediately in front of a pusher airscrew driven by the engine. A liquid cooled in line engine comprising a cylinder block 4, Figs. 1 and 2, and crank-case 5 is mounted on its side behind a spar 2 and a header tank 6 shaped to the wing profile is mounted above the crank-case. The engine drives a pusher airscrew 9 by means of an extension shaft enclosed by a fairing 8. A radiator comprising headers 13, 14 and cooling tubes 15 is mounted in a separate bay adjacent the engine, the cooling circuit being completed by radiator inlet and outlet pipes 10, 11, respectively and by an engine driven circulating pump. The assembly is enclosed by hinged inspection panels 16, 17 of which the upper panel shown open in Fig. 1, is apertured at 18 to permit access to filler 19 and the lower is formed with a set of parallel louvres 20 constituting air scoops. The cooling air is guided by a baffle 21 and escapes through a gap 22 in the wing trailing edge close to the airscrew which consequently exercises an extractor effect. According to modifications, the engine may be of the horizontally opposed type with a cylinder block on each side of the crank-case, or when an air cooled engine is installed the cylinders are positioned in the air stream through the wing. The louvres may be angularly adjustable and the area of exit gap 22 may be varied in flight.
