1. General
The engine/pylon connection is achieved by means of a two-mount system:
They allow for thermal expansion of the engine without inducing additional load into the mount system.
Engine mount bolts locking is achieved as follows:
The engine/pylon connection is achieved by means of a two-mount system:
Mounts- the forward mount: it is attached to the engine via the intermediate casing. It takes the X loads (thrust), Y loads (lateral) and Z loads (vertical),
- the aft mount: it is attached to the engine via the exhaust casing. It takes the loads in a plane normal to the engine centerline i.e.: Y loads (lateral), Z loads (vertical) and Mx (engine rotational inertia moment + Y load transfer moment).
They allow for thermal expansion of the engine without inducing additional load into the mount system.
Engine mount bolts locking is achieved as follows:
- Engine/nacelle interface: mechanical locking
- Nacelle/pylon: wirelocking (each screw has an independent lockwire or safety cable).
Each engine mount design provides dual load paths to ensure safe operation if one member fail.
