ABSTRACT:
A gas turbine engine mounting arrangement for attaching a gas turbine engine to a support structure, such as a pylon of an aircraft, comprises a main mounting member adapted to interconnect the engine with the pylon and transmit loads therebetween under normal engine operating conditions, and an auxiliary mounting member which is capable of interconnecting the engine with the pylon and transmitting loads therebetween in the event of failure of the main mounting member, the auxiliary mounting member being arranged to be substantially unloaded under normal engine operating conditions. The main mounting member includes a first primary load transmission means for transmitting vertical loads between the engine and the pylon and a second primary load transmission means for transmitting thrust and lateral loads between the engine and the pylon. The auxiliary mounting member includes a first secondary load transmission means for transmitting vertical loads between the engine and the pylon and a second secondary load transmission means for transmitting thrust and lateral loads between the engine and the pylon.
