摘要： A method and apparatus for detecting a missing phase in a 3-phase twelve-pulse autotransformer rectifier unit (ATRU) which, in use, receives a 3-phase input and delivers a nominal DC output on which a common-mode voltage is impressed. At least one of the frequency and amplitude of the common-mode voltage are monitored thereby to determine whether there is a missing phase in the input. The frequency and/or amplitude of the common-mode voltage may also be monitored thereby to determine whether there is a loss of input voltage.

摘要： A fuel supply system for an aircraft is provided for delivering in use fuel from a fuel tank to an aircraft powerplant. The in use fuel flows along a fuel flow passage from the fuel tank to the powerplant. A downstream pump is associated with the powerplant and configured to draw fluid along the fuel flow path so as to supply it to the powerplant in use. An upstream pump is disposed in or associated with the fuel tank and operable to pump fluid along the fuel flow passage. A pressure sensor is configured to monitor a pressure at an inlet to the downstream pump. A fuel system controller is responsive to the pressure sensor and configured to control the upstream pump so as to maintain the pressure at the inlet to the downstream pump at or above a predetermined threshold pressure.

摘要： A positive displacement pump system has first and second delivery passages for the pumped fluid and a main discharge passage. A control valve operating in dependence on the pressure drop across an orifice in the discharge passage diverts through overspill porting a proportion of the flow through the second delivery passage, the remainder added to the flow from the first delivery passage and passed to the discharge passage. The control valve also regulates the by-passing of a proportion of the flow from the first delivery passage to the overspill porting. As the said pressure drop increases, the control valve first increases the proportion of the flow from the second delivery passage diverted to the overspill porting and, as the pressure drop increases further, then commences to by-pass fluid from the first delivery passage to the overspill port, the quantity by-passed increasing with increase of said pressure drop. For a given movement of the valve member, the increase of effective area of communication between the second delivery passage and the overspill porting is greater than that between the first delivery passage and the overspill porting.

摘要： A valve for connecting an external tank to an aircraft has a valve body; and a seal assembly arranged, in use, to resiliently engage a seal surface on an aircraft. The seal assembly has a telescopic seal member extending from a proximal end within the valve body to a distal end. The telescopic seal member is constrained within the valve body so as to maintain axial alignment of the telescopic seal member and the valve body. The seal assembly may also have a seal carrier at the distal end of the telescopic seal member. The seal carrier may be pivotable relative to the telescopic seal member for alignment, in use, with the aircraft seal surface.

An attachment is configured to attach to a spool of the at least one valve and includes a clearance with respect to the first end of the rod so as to allow the attachment to move with the spool, during ordinary operation of the power system, without contacting the rod. A lever is connected to the second end of the rod and is configured to activate the manual override device by moving the rod in a longitudinal direction such that the first end of the rod makes contact with the attachment to move the spool.

摘要： An on board inert gas generation system for an aircraft receives air from a relatively low pressure source such as low pressure engine bleed air or ram air and passes it to a positive displacement compressor to increase the pressure thereof to be suitable for supply to an air separation module. The speed of the positive displacement compressor may be adjusted across a wide range in order to provide efficient operation in cruise and descent phases of aircraft flight. The operating speed of the compressor and/or the flow rate from the ASM to the space to be inerted may be controlled in accordance with at least one of the gas composition in the space to be inerted, the flight condition, and the ullage volume.

摘要： A roller or vane type pump is described of the kind in which the cam ring is pivotally mounted within an external casing to vary the throw of the cam ring and hence the pump delivery means is provided whereby a constant flow is obtained regardless of the pump speed. The cam surface of the cam ring is not wholly circular. The two portions of the cam surface extending between the inlet and outlet ports of the pump at opposite sides respectively of the pump axis have curvatures such that the instantaneous distance R.sub.2 of the point of contact of one of the sealing rollers or vanes with the cam surface from the axis of rotation of the rotor is given by R.sub.2 =.sqroot.R.sub.1.sup.2 +k where k is a constant and R.sub.1 is a corresponding instantaneous distance of the point of contact of the other sealing roller or vane with the cam surface from said axis.

摘要： The cam surface of a roller-type positive displacement pump providing an inlet port and two outlet ports has on circumferentially opposite sides of at least one of the outlet ports a profile such that the difference between the squares of the radii at the instantaneous points of contact therewith of the two rollers which serve to seal the port at said opposite sides is a constant. The portions of the cam surface at oposite sides of such an outlet port have radii relative to the axis of rotation of the rotor which decrease progressively in the direction of rotation of the rotor.

摘要： A positive displacement pump system has two delivery passages communicating under the control of a valve with a main discharge passage and/or an overspill duct. The valve is constituted by a valve member slidably mounted in a valve bore and the valve member has lands and intermediate recesses controlling communication between the delivery passages and the overspill duct. The pressures upstream and downstream of a discharge orifice in the discharge passage are applied to the valve member in opposition to each other, increase of the pressure drop tending to move the valve member to increase the amount of fluid passed to the overspill duct. To overcome the known tendency for a valve member to be subjected by the hydraulic forces to a large closing force when the valve is open to only a small extent, the valve is designed to provide for a relatively large opening force at least when the valve is commencing to open. In one construction this is achieved by passing the flow from the second to the main discharge duct through the valve member in a manner producing a jet reaction on the valve member to assist the normal regulating force on the member. In alternative arrangements the additional force is derived from an additional pressure drop induced in the flow from the delivery passage, the higher pressure being applied to valve member in a sense to increase the amount of fluid passed to overspill.
摘要翻译：正排量泵系统具有在阀门与主排放通道和/或溢流管道连通的两个输送通道。阀由可滑动地安装在阀孔中的阀构件构成，并且阀构件具有用于控制输送通道和溢流管之间的连通的平台和中间凹槽。排出通道中的排放孔的上游和下游的压力彼此相对地施加到阀构件上，倾向于使阀构件移动以增加流过溢流管的流体的量的增加。为了克服当阀门仅在很小的程度上打开时，液压力受到液压作用而产生大的闭合力的已知趋势，阀被设计成至少在阀门为止时提供相当大的开启力开始开放在一种结构中，这是通过以下方式实现的：通过在阀构件上产生喷射反应的方式，通过阀构件将流动从第二流到主排放管通过，以帮助构件上的正常调节力。在替代布置中，额外的力源自在来自输送通道的流动中引起的附加压降，在一定程度上施加较高的压力以增加流过溢流的流体的量。
