摘要:
A gearbox 104 for an auxiliary power unit (APU) 100 includes a front side defining a generator interface 120 configured to be coupled to a generator 108, the front side further defining an oil pump and fuel control component interface 176 configured to be coupled to an oil pump 112 and fuel control component 160, and a starter interface 122 configured to be coupled to a starter 122. The gearbox 104 further includes a back side on an opposite side to the front side and configured to house a gear train 128; a bottom side defining an oil tank interface 126 configured to be coupled to an oil tank 114; and a debris conduit 148 extending from the generator interface 120 to the oil tank interface 126.
摘要:
A flexible fitting (114) for connecting a plurality of rigid tubings (112) to form a tubing assembly including a housing (130), having a plurality of bores (132) defined therein and a plurality of tube fittings (122), each fixedly attached to an end portion of one of the plurality of rigid tubings (112) and disposed therein one of the plurality of bores (132). Each of the plurality of tube fittings (122) includes an o-ring channel (136) having an o-ring (128) disposed therein and in sealing contact with a sidewall of the housing (130) when the flexible fining is assembled. The combination of the tube fittings (122) and the o-rings (128) permit movement of tubing assembly, and more particularly the rigid tubing, about an axis of the tube fitting, translation along the axis of the tube fining, and provide angulation of the rigid tubing relative to the housing (130).

A combination filter includes a filter housing (104) having first and second inlet ports (122,126) and first and second outlet ports (124,128). A first filter bowl (110) is coupled to the housing. The first filter bowl inner surface defines a first cavity that is in fluid communication with the first inlet port and the first outlet port. A second filter bowl (112) is coupled to the housing and is at least partially disposed within the first cavity of the first filter bowl (110). The second filter bowl (112) defines a second cavity that is in fluid communication with the second inlet port (126) and the second outlet port (128). A first filter (106) is disposed within the first filter bowl (110) for filtering fluid that flows between the first inlet port (122) and the first outlet port (124), and a second filter (108) is disposed within the second filter bowl (112) for filtering fluid that flows between the second inlet (126) and outlet (128) ports.

摘要:
An eductor assembly (104) is provided that includes a primary nozzle (114), a cooler plenum (120), and a surge plenum (122). In one embodiment, and by way of example only, the primary nozzle (114) is configured to accelerate and discharge turbine exhaust gas therefrom and the cooler plenum (120) surrounds the primary nozzle (114) and includes at least a fluid inlet (134) and a fluid outlet (136). The surge plenum (122) partially surrounds the primary nozzle (114) and the cooler plenum (120) and includes at least a fluid inlet (154) and a fluid outlet (156). The surge plenum fluid outlet (156) axially aligns and is coterminous with the cooler plenum fluid outlet (136).
