Patent ID: 7438262

Claim:
A gas turbine engine mounting arrangement for attaching a gas turbine engine to a support structure, the mounting arrangement comprising: a main mounting member interconnecting the engine with the support structure and transmit loads between the engine and the support structure under normal engine operating conditions; an auxiliary mounting member interconnecting the engine with the support structure and transmitting loads therebetween in the event of failure of the main mounting member, the auxiliary mounting member arranged to be substantially unloaded under normal engine operating conditions; characterized in that the main mounting member includes a first primary load transmission means for transmitting vertical loads between the engine and the support structure and a second primary load transmission means for transmitting thrust and lateral loads between the engine and the support structure, and in that the auxiliary mounting member includes a first secondary load transmission means for transmitting vertical loads between the engine and the support structure and a second secondary load transmission means for transmitting thrust and lateral loads between the engine and the support structure; wherein said second primary load transmission means comprises a second primary load transmission pin and said second secondary load transmission means comprises a second secondary load transmission pin; wherein the main mounting member and the auxiliary mounting member are mounted together, wherein the second secondary load transmission pin extends into a central longitudinally extending passage of the second primary load transmission pin; and wherein the auxiliary mounting member is interposed between the main mounting member and the support structure, in use.
