Abstract: A one-way speed limiter includes a first housing including an inner surface. defining a speed limiter receiving zone. A second housing includes a flange and a second wall including an inner surface portion that includes a stop feature. A ball housing including a ball member is rotatably supported in the speed limiter receiving zone. The ball member selectively engages the stop feature. A friction clutch is disposed between the ball housing and the first housing. The friction clutch selectively retards rotation of the ball housing. A motor shaft is selectively rotatably connected to the ball housing. The motor shaft including a first end supported at the ball housing and a second end. The motor shaft is rotatable relative to the ball housing in a first direction and selectively rotatably constrained relative to the ball housing in a second direction to selectively engage the friction clutch.

Abstract: A nut for use in an actuator assembly having a rotatable screw includes an outer nut portion and an inner nut portion removably coupled to the outer nut portion. The inner nut portion is rotatably couplable to the rotatable screw. At least one anti-rotation pin is positionable between the outer nut portion and the inner nut portion to restrict rotation of the inner nut portion relative to the outer nut portion.

Abstract: A rod assembly includes a tubular rod body formed from a composite material and a localized sleeve installed to the rod body. The sleeve is secured to the rod body by application of heat to the sleeve material. A bushing is located radially between the rod body and the sleeve. The bushing is configured to absorb thermal energy of the application of heat. A door and hold open rod assembly of an aircraft includes a door, and a hold open rod assembly secured to the door. The hold open rod assembly is configured to support the door in an opened position when the hold open rod is deployed. The hold open rod assembly includes a tubular rod body formed from a composite material, and a localized sleeve installed to the rod body. A bushing is located radially between the rod body and the sleeve.
