Patent ID: 7461815

Claim:
A system for suspending a rotor drive engine ( 21 ) to an aircraft airframe ( 26 ), the system comprising: at least one device ( 10 ) for suspending the engine to the airframe, each device ( 10 ) including i) two attachment portions ( 13 , 17 ), a first of the two attachment portions for connecting the device to the engine and a second of the two attachment portions for connecting the device to the airframe, and ii) a deformable structure ( 20 ) lying between the two attachment portions ( 13 , 17 ), wherein, the deformable structure ( 20 ) comprises a plurality of blades ( 37 , 38 ), each suspension device further has a compression abutment ( 43 , 44 ) configured to limit an extent to which the suspension device can be shortened by a deformation of the deformable structure ( 20 ), and each suspension device has a first extension abutment configured to limit an elongation of the device, the elongation by deformation of the deformable structure, to a first elongation value, and a second extension abutment configured to limit the elongation to a second elongation value, wherein the second elongation value is greater than the first elongation value.
