Abstract: A bleed valve assembly for discharging bleed air into a gas turbine engine bypass plenum includes a bleed flow duct, a bleed valve, and a flow deflector. The bleed flow duct is contoured such that it delivers uniformly flowing bleed air to the flow deflector when the bleed valve is in the open position. The flow deflector has a plurality of openings formed therein. Each opening fluidly communicates the bleed air flow passage with the bypass plenum. A portion of the openings are oriented at a discharge angle such that bleed air is discharged from each opening in a direction that does not have a vector component in the direction in which air is flowing in the bypass plenum, and another portion of the openings are oriented to provide stress relief to the deflector.

Abstract: An apparatus is provided for a valve assembly comprising a valve body, a valve element, an actuator housing, an actuator, an unlocked storage opening, a locked storage opening, and a lock. The valve body has an inlet port, an outlet port, and a flow passage therebetween. The valve element is movably disposed within the valve body flow passage. The actuator is disposed within the actuator housing, coupled to the valve element, and operable to move the valve. The unlocked and locked storage openings are formed in the actuator housing. The lock is selectively insertable into, and movable between, the unlocked and locked storage openings. When in the unlocked storage opening, the lock does not engage the actuator, and valve movement is thereby allowed. When in the locked storage opening, the lock engages at least a portion of the actuator, thereby at least inhibiting valve movement.

Abstract: A valve actuator is provided that comprises a unitary housing and a piston translatably mounted within the housing. The piston comprises a first portion having a first diameter and a second portion having a second diameter that is greater than the first diameter. A position sensor having a third diameter at least as large as the second diameter is fixedly coupled to the housing and to the piston for determining the position of the piston.

Abstract: Anti-ice valve components are provided that include a servo housing, a valve body, and a transfer tube. The servo housing includes a surface having a cavity formed therein. The valve body is spaced apart from the servo housing and includes a surface having a cavity formed therein. The transfer tube has a first end, a second end, and a length, where the first end is disposed in the servo housing cavity, the second end is disposed in the valve body cavity, and the length extends between the first end and the second end and has a portion forming a bend of at least 180 degrees.

Abstract: Butterfly valves are provided that include a flowbody, a butterfly plate, and a coating. The flowbody has an inner surface defining a channel. The butterfly plate is disposed in the channel, is rotationally mounted to the flowbody, and has an outer periphery. The coating is disposed on at least a portion of at least one of the flowbody inner surface and the butterfly plate outer periphery and is made of a material formulated to abrade upon friction contact with an adjacent surface and to maintain structural integrity when subjected to pneumatic forces of at least 600 psi.
