A starter generator located within a sump region of a turbofan engine and coupled to an adapter shaft. The adapter shaft rotationally coupled to the high pressure shaft, forward of a high pressure shaft bearing, and secured by a spanner nut. The engine makes use of two pluralities of electrical conductors, the first extends through an electrical conduit defined by a forward strut extending from the sump region to the outward casing, the second extends axially away from the electric starter. Each of the first plurality of electrical conductors makes reversible contact with a respective one of the second plurality of electrical conductors via an elbow/pin connector, producing a tight turn in area of limited space.

Starter/generator

A nose cone and fan assembly are disclosed. The fan assembly comprises a fan rotor and a nose cone retention flange. The fan rotor at least partly defines a fan assembly air flow boundary surface. The nose cone retention flange extends from the fan rotor and comprises a retention flange air flow boundary surface adjacent the fan assembly air flow boundary surface and a nose cone mating surface. The nose cone comprises a nose cone flange having a rotor mating surface. The nose cone is affixed to the nose cone retention flange with the rotor mating surface overlaying the nose cone mating surface of the nose cone retention flange.

Nose cone and fan assembly

According to one aspect, a genset includes a gas turbine engine having a low pressure shaft wherein the gas turbine engine is adapted to provide mechanical power to a propulsion type load. The genset further includes a generator having an input power shaft wherein the generator is adapted to receive mechanical power to develop electric power. The genset further includes an output power shaft having a first end coupled to the low pressure shaft of the gas turbine and a second end coupled to the input power shaft of the generator and a plurality of struts wherein the first ends of the plurality of struts are coupled to the gas turbine engine and second ends of the plurality of struts are coupled to the generator at locations substantially aligned with a center of gravity of the generator. A suspension apparatus attaches the gas turbine engine and the generator at mounting locations substantially aligned with a gas turbine engine center of gravity and at mounting locations substantially aligned with the generator center of gravity, respectively.
