摘要： A system for generating supplemental electrical power from the low-pressure (LP) turbine spool of a turbofan engine includes a high-speed, high magnetic pole count, generator, a gearbox, a controller and a power converter. The LP turbine spool is mechanically coupled to the generator portion by the gearbox for driving the generator portion. The controller portion has a speed-sensing element for sensing the LP turbine speed. The controller portion disables the power converter when the generator exceeds a predetermined speed, and enables the power converter when the generator portion is less or equal to the predetermined speed. The effective load on the generator is reduced to approximately zero when the LP turbine spool exceeds the predetermined speed, permitting the generator to be electrically bound up to the predetermined speed and mechanically bound in excess of the predetermined speed.

摘要： An inside out generator disposed aft of the low-pressure turbine spool to generate power for the electrical demands of an aircraft system. The low-pressure turbine discharge flow is used to drive the power turbine, which is coupled to the generator. The generator is able to extract power at idle conditions of the aircraft engine from ducting the discharge through the inside out generator. The system eliminates the placement of a generator in the hot gas path of the discharge, and enables the injection of power directly to the accessory gear box of the engine.

摘要： A chain-belt adapted for use in a pulley drive system and comprising a plurality of connected ranks or sets of interleaved links having generally trapezoidal load blocks between adjacent pivot means which join the adjacent ranks or sets of links together to permit articulation of the chain belt. The load blocks are of generally laminated construction of a plurality of plates and resilient means are located between adjacent plates in at least some of the load blocks. Preferably an elastomeric material such as rubber is chosen as the resilient means and each load block incorporates the resilient means.The structure is effective to reduce noise generated upon engagement and disengagement of the chain-belt with the pulley flanges when compared to a chain-belt of connected ranks of links and with laminated load blocks therein but without the resilient means.

摘要： An electrical generator for extraction of electrical power from a gas turbine engine includes a rotor portion and a stator portion disposed within a booster cavity of the gas turbine engine. The rotor portion is rotatably supported about the stator portion. The stator portion rigidly is supported within the booster cavity. The rotor portion has a plurality of poles circumferentially arranged opposite the stator portion. The stator portion includes a plurality of coil portions disposed about an outer periphery of the stator portion adjacent to the stator portion. The stator and rotor portions are configured to generate electrical power when the rotor portion is rotated about the stator portion by a shaft of the gas turbine engine to induce electrical currents in the coil portions. The electrical generator extracts electric power from the turbine engine to supplement primary electrical generation sources of the engine.
