DIESELS: A Prototype Airplane with a Diesel Engine-Lucas: 48. The P-51 Mustang used an aft-fuselage-mounted radiator, while the P-40 Warhawk’s was mounted beneath the engine. The propeller shaft bearings should be sized to support the propeller thrust loads plus the gyroscopic loads caused by maneuvering. Hose clamps should be constant-tension type, and two clamps per hose end provide extra safety. The function of the exit duct is exactly opposite: contracting gradually to increase air velocity. To compare these in more detail, we need some definitions: The rate at which the engine does work.
