Abstract
A nacelle of a gas turbine engine is attached via a pylon to an aircraft wing from which the engine is to be mounted. The nacelle is split to form a pair of opposing arcuate doors which are moveable between an open position and a closed position. When the doors are closed a ring on the fan casing locates in a correspondingly shaped groove on the inner surface of the arcuate doors. The nacelle is structurally integrated with the fan casing with the ring so that all the engine loads are transmitted through the nacelle. Telescopic struts are provided to connect the engine casings directly to the pylon so that when the arcuate doors are open, to allow access to the engine, the struts 50-60 support the engine.
Claims13
A mounting arrangement for a gas turbine engine comprising a nacelle surrounding the casing of a gas turbine engine, the nacelle being attached via a support member to an aircraft structure from which the engine is to be mounted, at least a part of the nacelle being split to form a pair of opposing arcuate doors which are moveable between an open position to allow access to the engine and a closed position, there being provided means for structurally integrating the arcuate doors with the engine casing when the arcuate doors are closed so that all the engine loads are transmitted through the nacelle, there being further provided connecting means to connect the engine casing directly to the support member so that when the arcuate doors are open, the further connection means support the engine, all the engine loads being transmitted through the engine casing.
