Mounts for Turbofan Engines

  • The engine mounts on most turbofan engines perform the same basic functions of supporting the engine and transmitting the loads imposed by the engine to the aircraft structure.
  • Most turbine engine mounts are made of stainless steel and are typically located. Some engine mounting systems use two mounts to support the forward end of the engine and a single mount at the rear end and a 3.6 Pentastar like engine masters.
  • Turbine Vibration Isolation Engine Mounts
  • The vibration isolator engine mounts support the power plants and isolate the airplane structure from adverse engine vibrations.
  • Each power plant is generally supported by forwarding vibration isolator mounts and an aft vibration
  • isolator mount.
  • The forward vibration isolator engine or amc1200b  mounts carry vertical, side, and axial (thrust) loads and allow engine growth due to thermal expansion.
  •  The aft mounts take only vertical and side loads; however, they will also accommodate thermal
  • expansion of the engine without applying axial loads to the engine flanges.
  • The vibration isolators consist of a resilient material permanently enclosed in a metal case.
  •  As an engine vibrates, the resilience therapy material deforms slightly, thereby dampening the vibrations before they reach the airplane structure.
  • If complete  failure is an option  or loss of the resilience therapy material occurs, the isolators will continue to support the engine.
