Abstract
521,708. Mounting aircraft engines. JULIEN, M. F. A., and ROCARD, Y. A. Nov. 22, 1938, No. 33904. Convention date, Nov. 23, 1937. [Class 4] An aeroplane engine mounted with torsional and radial elasticity upon supports which are subjected to reciprocating vibrations during flight, has the radial elasticity of the suspension in the direction of the characteristic vibrations of the support designed to bring the engine and the support nearly into resonance, damping means being added to the system. Fig. 4 shows an engine mounted on resilient blocks 3 giving radial and torsional elasticity as in Specification 451,577, additional members 5 giving added elasticity in a vertical direction. The elasticities of the blocks 3 and members 5 are so chosen as to give a vertical vibration frequency equal to or less than the characteristic pulsations of the wing on which the engine is mounted. The members 5 may be omitted and the elasticity of the blocks 3 suitably varied, or a hydraulic damping device may be added. Fig. 6 shows an engine nacelle suspended from a wing by resilient members 5, 5<1> controlled by a hydraulic damper 7.
