engine mounting schemes helicopters

The engine mount should take the load coming to its crankcase (torque M, axial and radial components of the weight G and the inertial forces), have temperature and installation of expansion joints and shock absorbers. CMP engine mounts are designed for a particular type of engine, taking into account operational requirements (access to all components and elements of the engine mounting, minimum labor input of assembly and disassembly of the engine).

The supports are installed vibration damper in the form of rubber sleeves 5. In connection with the change in the volume zone B-B when it is heated when the engine is started, one of the supports must be provided a linear equalizer, allowing longitudinal movement of the finger of the mount casing relative to its support on the fuselage.

The rear engine mount can be placed on a spherical centering hinge mounted on the crankcase GR. The outer part of the spherical hinge is attached to a cantilever tube attached to the engine crankcase. Inside the tube, a shaft passes connecting the free turbine of the engine through a gear coupling to the MSH GR. The pivot bearing senses axial and lateral forces from the engine. Elements of the front support perceive torque from the engine, part of the longitudinal and transverse loads from the weight of the engine.
