Abstract: A system for connecting and supporting foam ducting in, e.g., an aircraft. A slip joint element connects segments of the ducting and a sliding support element supports the ducting while accommodating an axial movement of the ducting due to thermal expansion and contraction or other operational forces. The slip joint includes male and female components installed on ends of adjacent segments of ducting. The male component is slidingly received within the female component, such that when the segments move along the axis the male component slides but remains received within the female component. The sliding support includes a receiver component slidingly received within a channel of a mounting component. The receiver component engages a fixed support bracket structure and the mounting component is mounted on an exterior surface of the ducting, such that when the ducting moves along the axis the receiver component slides but remains received within the channel.

Abstract: Embodiments of the present invention provide a locking device (20) operable to prevent accidental deployment of a pivot door thrust reverser. The locking device (20) generally comprises a pin lock receiver (32) operable to fixedly couple with a pivot door (18), a housing (34) operable to be coupled with a nacelle (14), and a piston (36) having a pin lock (38). The piston (36) is at least partially positioned within the housing (34) and is operable to be actuated between a locked position and an unlocked position. In the locked position the pin lock (38) is operable to mate with the pin lock receiver (32) and in the unlocked position the pin lock (38) is detached from the pin lock receiver (32) to allow deployment of the pivot door (18). Such a configuration allows pivot door thrust reversers to be locked without requiring the use of heavy and cumbersome parts.
