Abstract

723,452. Aircraft engine mountings. BELL AIRCRAFT CORPORATION. June 6, 1952, No. 14338/52. Class 4. A mounting of a power unit consisting of an engine, driving shaft, and propeller, in the frame of a vehicle, e.g. a helicopter, is characterized in that the mounting means enable the unit to oscillate universally about the centre of percussion of the unit for a force of given resultant frequency directed laterally against the propeller, and in that elastic restraining means restrain the oscillations. In Fig. 1, engine 16, shaft 14, and propeller 10 form a unit mounted to pivot about the centre of percussion for lateral forces acting on the propeller hub 12, said centre of percussion being below the centre of gravity 17. The engine is pivoted to frame 18 at 20, which frame may oscillate about axis B-B on rubber bush bearings 22 with respect to the vehicle frame members 30. Restraining springs 32 are connected between the unit and the frame. In a further embodiment, Fig. 6, the unit has a gear section 42 fast to the spider 46, which is mounted through resilient pads 48 on the frame 52 fast to the vehicle, so that the centre of percussion lies in the plane of the spider 46, and oscillation may take place about this point.
