摘要:
A two-speed transmission having an input shaft and an output shaft, the transmission being capable of transitioning between fixed ratios, the high-range ratio being direct 1:1 and the low-range ratio being about 2:1. The transmission is a simple lightweight, yet robust, configuration utilizing only two gear meshes, being comprised of an input gear, a cluster gear, and an output gear. The transmission is controlled with a clutch and a sprag and with the input and output shafts turning in the same direction.

A hybrid gear consisting of metallic outer rim with gear teeth and metallic hub in combination with a composite lay up between the shaft interface (hub) and gear tooth rim is described. The composite lay-up lightens the gear member while having similar torque carrying capability and it attenuates the impact loading driven noise/vibration that is typical in gear systems. The gear has the same operational capability with respect to shaft speed, torque, and temperature as an all-metallic gear as used in aerospace gear design.

In a turbine machine, a two component shroud seal which maximizes insulation and sealing around the rotating turbine blades and made by independently fabricating each of the two components then joining them together is disclosed. The two components may be joined together at room temperature. The resulting shroud seal provides greater engine efficiency and thrust.
摘要:
A flushing system for flushing away any coking material which may have built up in the bearing of a gas turbine. Three fluid tanks respectively contain a solvent for dissolving the coked material, a cleaner and a lubricant. By means of a three-way valve, one of the fluids is provided to a supply pump for delivery to the bearing housing via a quick disconnect coupling. Fluid is returned to the appropriate tank by means of a return pump, via a quick disconnect coupling and another three-way valve between the return pump and the tanks. The system includes respective filters for filtering the return fluids and the entire system may be carried on a wheeled cart for servicing the gas turbine.
