摘要： A self priming gear pump 14 for pumping liquids containing gases is provided with a vent pipe 26 for releasing entrapped gases that would otherwise collect at the outlet side of the pump 14. The vent pipe 26 terminates within the pump housing 21 at a zone which is out of the path of the oil centrifuged by the gears 25 and in the region lying near the point of intersection of the gears 25. An additional inlet pipe 27 which directs liquid across the main inlet into the gap between the periphery of one of the gears 25 and the housing 21 may be provided to improve liquid sealing.

摘要： A gas turbine engine pod installation comprises a core engine with a stiff carcase from which the engine is supported from a pylon. The core engine drives a fan which operates within a fan casing extending to downstream of the core engine nozzle so that the core and fan flows are mixed to provide propulsive thrust when they exit from the fan duct nozzle. The fan casing is supported from the core engine carcase by forward and rearward supports so that these supports, the fan casing and the carcase form a stiff loop of structure which supports and stiffens the carcase.

摘要： A gas turbine engine has an axial flow compressor, the inner wall of which is provided with a lining adapted to capture and retain any small hard foreign objects impinging upon it. The lining consists of an aluminum alloy sheet having a silicone rubber coating bonded to one side and a stainless steel honeycomb structure bonded to the other side. The honeycomb structure is bonded in turn to the inner wall of the compressor casing. The silicone rubber coating has a plurality of finely divided hollow silica microspheres dispersed within it.

摘要： A fully aerobatic oil system for an aircraft gas turbine engine includes two re-circulatory oil systems the pumps for which have inlets 19 and 31a disposed at locations in the engine such that when one inlet is starved of oil, due to the aircraft attitude changing, oil will be supplied to the other one. In a specific embodiment, the breather of the oil system 30 (FIG. 2) is positioned in the engine gearbox and provides the lowest pressure point in the system. The breather is of the type described in UK Pat. No. 1,508,212 which includes a rotating compartment filled with RETIMET (Regd. Trade Mark). The bearing chambers are pressurised with air from the engine and the air/oil mixture in each chamber is vented via a first series of vents 24 to the breather where the air and oil are separated. The breather is used as a pump to pump the separated oil back to the oil tank via a scavenge line 35 which includes a relief valve 38. A bleed line 36 takes some of the oil from line 35 to the main oil supply gallery 23 via a non-return check valve 37. In normal flight pump 20 supplies the gallery 23 from the tank 18 via pump inlet 19, the relief valve 38 being set to a pressure lower than that of relief valve 40 which controls the pump pressure. The check valve 37 thus remains shut. When the inlet 19 is starved of oil because the flight attitude of the aircraft changes, the pressure in gallery 23 drops to the extent that check valve 37 opens and the breather/pump takes over circulating oil from the gearbox and bearings around the second system.
