Abstract: A fuel supply system includes a fuel pump having a bottom inlet end configured to pick up fuel and a top discharge end configured to discharge fuel at a pressure higher than that of the inlet end. A housing defines a pressure vessel in fluid communication with the discharge end of the fuel pump. The fuel pump is secured with respect to the housing so that the pressure vessel is laterally adjacent the fuel pump and the pressure vessel and the fuel pump have overlapping heights. Exactly one check valve is positioned between the discharge end of the fuel pump and the pressure vessel, and the check valve is spaced laterally away from the discharge end of the fuel pump at an inlet to the pressure vessel.

Abstract: A double axis frame strut has a strut frame and a tongue that extends from a distal end of the strut frame. The tongue can be rigidly coupled to an axle that is rotatably coupled to the strut frame and extends from a distal end of the strut frame. The tongue can rotate relative to the strut frame and the tongue can include a hole which can be coupled to other double axis frame struts or other structure. The hole in the tongue can define a first axis of rotation and the axle can define a second axis of rotation. The axis of the hole in the tongue can be perpendicular to the axis of rotation of the tongue relative to the strut frame.

Abstract: A fuel supply system includes a fuel supply pump and a jet pump that utilizes the flow from the supply pump to supply fuel to a fuel pump reservoir from a main fuel tank. The jet pump includes a body. A main inlet of the body is coupled to the outlet of the supply pump, and a nozzle is positioned on an interior of the body. A mixing tube is defined by the body downstream of the nozzle, and defines a channel extending along an axis. A suction inlet of the body is in fluid communication with the mixing tube channel. An outlet conduit of the body extends from the channel at least partially in a direction away from the axis, and an outlet of the body positioned remotely from the channel along the outlet conduit. The outlet is positioned at or above an upper portion of the reservoir such that fuel pours down into the reservoir.

Abstract: A rotor, such as a fan of a gas turbine engine, comprises blades 2 and annulus fillers 4 which extend between adjacent blades 2. Gaps 22 between each blade 2 and the adjacent annulus fillers 4 are sealed by sealing elements 8. The sealing elements 8 fit closely around the profile of the blade 2 and have annulus filler sealing surfaces 18 for sealing contact with the annulus fillers 4. The sealing elements 8 have low-friction blade sealing surfaces 12 so that, when the fan is rotating, centrifugal loading displaces the sealing elements 8 radially outwardly so that the annulus filler sealing surface 18 make sealing contact with the annulus fillers 4.

Abstract: An annulus filler for installation between blades, such as fan blades, of the rotor of a gas turbine engine includes a channel which accommodates a post defined between blade slots of the disc. A chocking surface of the annulus filler contacts regions of a contact surface of the post to chock the head of the post within the channel. The annulus filler is thus supported along the axial length of the post, enabling it to withstand circumferential forces generated on rotation of the disc.

A composite nose cone is also provided comprising an attachment region A, in which composite fibres are oriented substantially perpendicular to an axis of rotation of the nose cone 104, and an impact region I, in which composite fibres are oriented substantially parallel to the axis of rotation of the nose cone 104. Also provided is a support ring 106 for a nose cone assembly, the support ring 106 comprising an annular main body 140 and an annular projecting attachment flange 142, the attachment flange 142 terminating in a plurality of circumferentially spaced attachment tabs 144, wherein the attachment flange 142 forms with the main body 140 a cross section having at least two C curves 160, 162.

Abstract: A fuel system for use in a fuel tank having first and second tank portions includes first and second fuel pumps in the first and second tank portions, respectively. A first fuel reservoir is provided in the first tank portion and a second fuel reservoir is provided in the second tank portion. A first crossover fuel line extends between the first and second tank portions, and a second crossover fuel line extends between the first and second tank portions. A first jet pump in the first tank portion communicates with the first crossover fuel line for transferring fuel through the first crossover fuel line to the second tank portion, and a second jet pump in the second tank portion communicates with the second crossover fuel line for transferring fuel through the second crossover fuel line to the first tank portion.

Abstract: An annulus filler is provided for mounting to a rotor disc of a gas turbine engine. The filler comprises a lid for bridging the gap between two adjacent blades attached to the rotor disc. The filler further comprises forward and rearward hook members projecting below the lid and configured to respectively engage with forward and rearward outwardly directed hooks provided on the rotor disc when the annulus filler is translated in a generally rearwards direction on mounting of the annulus filler to the rotor disc. The filler can further comprise a lip extending from the rear of the lid, the lip being configured to fit beneath a gas-washed element located rearwards of the annulus filler. One or more guide ramps then extend from the rear of the lip, the or each guide ramp being angled down relative to the lip to encourage the lip to slide beneath said fairing when the annulus filler is translated in the generally rearwards direction.

Abstract: A fuel supply system is provided for delivering fuel from a tank to an engine of a motor vehicle through a fuel line. The system is provided with a pressure relief valve to divert fuel from the fuel line during engine shut down conditions when fuel flow to the engine is not desired. The pressure relief valve has a fuel outlet that is provided with backpressure during engine operation. The backpressure enables the pressure relief valve to be set at a lower level because the backpressure is added to set point pressure to determine opening of the pressure relief valve. Lowering the set point of the pressure relief valve allows fuel to be diverted from the engine at a lower fuel line pressure. In one embodiment backpressure is provided by fluid communication from a jet pump supplying fuel from the fuel tank to a fuel system reservoir.

Abstract: A check valve includes a body defining a passageway through which fuel flows in a first fuel-flow direction during pump operation. The check valve also includes a seat, a seal member, and a biasing member biasing the seal member toward the seat. The seal member is movable between a first seated position in which the seal member is engaged with the seat and the pressure in the fuel rail is substantially equal to the operating pressure, and a second seated position in which the seal member is engaged with the seat and a residual pressure in the fuel rail is substantially less than the operating pressure. The seal member and the seat define a leak path between the fuel pump and the fuel rail permitting fuel to flow in a second fuel-flow direction opposite the first fuel-flow direction when the seal member is in the second seated position.

Abstract: A fuel pressure relief valve includes a body defining a passageway having an inlet end in communication with a fuel pump and an outlet end in communication with a fuel rail. The valve also includes a seal member moveable between a first position in which the seal member is seated against the outlet end, and a second position in which the seal member is unseated from the outlet end. The valve further includes a biasing member biasing the seal member toward the second position. The seal member moves from the second position to the first position immediately after fuel pump shutoff to maintain pressure in the fuel rail. The seal member moves from the first position to the second position when fuel in the fuel rail drops to a residual pressure substantially less than the operating pressure to provide a leak path between the fuel pump and the fuel rail.
