摘要： A reverse flow combustor has an inlet end. A flowpath extends downstream from the inlet end through a turn. The turn directs the flowpath radially inward and reversing an axial flow direction. A large exit duct (LED) is along the turn. A small exit duct (SED) is along the turn and joined by a joint to a mounting structure to resist separation in a first axial direction. The joint comprises: a first surface on the SED facing partially radially inward; and a mounting feature engaging the first surface.

摘要： An actuation system for pivoting a flap on a helicopter rotor blade to reduce the interaction of the blade with the preceding blade vortex. The actuation system includes a fluid supply which is connected to first and second fluid supply lines. The fluid supply lines convey flows of pressurized fluid from the fluid supply to an actuator. The actuator includes a housing mounted within the rotor blade and having a channel formed in it. A butterfly shaft is pivotally mounted within the channel and has laterally extending arms which separate the channel into four lobes. A first port connects the first fluid supply line with two diametrically opposed lobes in the channel. A second port connects the second fluid supply line with the other two diametrically opposed lobes in the channel. A torque coupling is attached to the butterfly shaft and engaged with the flap such that rotation of the torque coupling produces concomitant rotation of the flap. The pressurization of the first fluid supply line causes the torque coupling to rotate in a first direction. The pressurization of the second supply fluid line causes the torque coupling to rotate in the opposite direction.

摘要： A braze-free connector suitable for use in a refrigeration system that includes a connector body having a circular opening passing therethrough. The opening has a converging section that tapers downwardly from the entrance to the opening toward the back of the opening. A ferrule is slidably mounted upon a refrigerant tube which is inserted into the opening to place a tapered collapsible section of the ferrule in contact with the tapered section of the opening. The non-collapsible section of the ferrule is keyed to a nut which in turn is mated with a male thread formed on the connector body whereby the collapsible section of the ferrule is forced into engagement with the refrigerant tube. A pressure sensitive sealant is pre-coated upon at least the collapsible section of the ferrule which is activated as the ferrule is forced into engagement with the refrigerant tube.
