These compression type couplings consist of bonded rubber joints pressed into the sockets of metal hubs. These dynafocal engine suspensions provide proper flexible support to isolate engine vibrations and reduce noise transmission to airframe structure in all aircraft applications. Careful design assures maximum strength to hold the engine under ultimate load and emergency conditions.
Suspensions also distribute loads in most desirable patterns, control engine motions, accommodate thermal expansion and manufacturers’ tolerances.
