ABSTRACT:
A main thrust link having a forward end connected to the engine core housing at a first forward location, and extending rearwardly and moderately upwardly therefrom to connect to a main support structure at a second rearward location. Connected to the rear of the engine core housing is a rear support device designed to resist vertical loads generally parallel to the vertical force component exerted by the main thrust link, and also to resist side loads. There is a forward connecting device interconnecting the fan casing with the support structure at a location forward of the forward connecting location of the main thrust link. This forward support device comprises a plurality of tangential links connecting to the fan casing at evenly spaced locations around the circumference of the fan casing, thus resisting not only vertical loads, but also resisting torsional loads and side loads on the engine. The forward and rear support devices exert a force couple substantially balancing the force couple created by the thrust link co-acting with the thrust force developed by the engine, and the forward and rear support devices additionally distribute the bending moments on the engine on both sides of the forward connecting location of the thrust link to diminish the maximum bending moment exerted on the engine.
