Abstract
A system for supporting an auxiliary power unit in an aircraft tailcone wherein the auxiliary power unit is supported by a focalized suspension system supporting the power unit, the focalized suspension system having a plurality of support means each having a line of action, the lines of action intersecting at the focal point. The support system simplifies removal and installation of the auxiliary power unit from and into the aircraft's tailcone.
Claims19
An aircraft auxiliary power unit combination located in an aircraft for supplying electrical power to the aircraft comprising:
- A. an auxiliary power unit, said power unit comprised of an electrical power generator and a prime mover with said generator driven by said prime auxiliary power unit having a center of gravity;
- mover, said auxiliary power unit having a center of gravity;
- B. a focalized suspension system supporting the power unit within the aircraft, the focalized suspension system having a plurality of focalized support isolator mounts for minimizing a vibration and a displacement of said auxiliary power unit, each of said focalized support isolator mounts having an inwardly angled line of action, said inwardly angled lines of action intersecting at a focal elastic center, said focal elastic center proximate said auxiliary power unit center of gravity.
