1. The method of mounting a turbine engine in a fixed-wing aircraft or the like for driving a propeller comprising the steps:

  • providing a unitary open rigid support frame having a frame ring and rigid support sturts rigidly connected to the ring and extending forwardly therefrom,detachably but rigidly connecting a gearbod for driving the propeller to the free ends of said struts, with the input shaft of the gearbox extending toward the ring,nonresiliently suspending the turbine engine from the frame ring inwardly of the ring and independently of the gearbox and in a position spaced from the gearbox with an output shaft of the engine axially aligned with, but spaced from an input shaft of the gearbox using inelastic suspension means which enable thermal expansion and contraction of the engine relative to the frame ring while restraining the engine against any substantial bodily movement relative to said ring,flexibly coupling the output shaft to the input shaft to drivingly interconnect the engine output shaft and the gearbox input shaft and to accommodate both slight axial misalignments and slight relative axial movement of said shafts,and resiliently connecting the frame ring to an airframe portion of the aircraft.
