Abstract: A method of manufacturing a hybrid metal-composite component unit. The method comprises: providing a thermoplastic composite component comprising non-consolidated material and/or consolidated material; providing at least one metallic connecting component comprising at least one vent hole; forming a form-fit connection between the at least one metallic connecting component and the thermoplastic composite component, wherein the at least one metallic connecting component encompasses the thermoplastic composite component in an overlap area having the at least one vent hole; and heating the at least one metallic connecting component and the thermoplastic composite component in the overlap area for melting the thermoplastic composite component in the overlap area at least partly such that thermoplastic material of the thermoplastic composite component passes through the at least one vent hole.

Abstract: A deceleration mechanism for a door system. In particular, a door system that is adapted to control an opening of a door module that separates compartments of an aircraft, the door module comprising a door panel that performs a rotational movement above a floor structure of the aircraft during an opening of the door module, comprises a deceleration mechanism that comprises a bolt, a bolt moving mechanism that is attached to the bolt, a latch mechanism that is removably connected to the bolt moving mechanism an activation mechanism that is attached to the latch mechanism, and a brake element that is rigidly attached to the bolt.

Abstract: A door system with a deceleration mechanism may be adapted to control an opening of a door module that separates compartments of an aircraft and includes a door panel and a door frame. During the opening of the door module, the door panel performs a rotational movement 389 above a floor structure of the aircraft. The deceleration mechanism is operable in a normal operation mode and a deceleration mode and comprises a hinge, a wedge-shaped component that is rotatably attached to the hinge, and an activation device. The activation device is coupled to the wedge-shaped component and switches the deceleration mechanism from operating in the normal operation mode to operating in the deceleration mode when a difference in pressure between the compartments exceeds a predetermined threshold.

Abstract: A door opening system with a deceleration mechanism may be adapted to control an opening of a door module that includes a door panel and a door frame. Deceleration mechanism may include strap that connects door panel with door frame, spool, and spool. Spool may receive one end of strap, is biased to roll up a first portion of strap, and adapted to perform a first unwinding of the first portion of strap. Spool may receive a second end of strap, is biased to roll up a second portion of strap, and adapted to perform a second unwinding of the second portion of strap from spool. Spool may include a braking apparatus that is adapted to decelerate the second unwinding when a velocity of the second unwinding is above a predetermined threshold.

Abstract: A door locking system for a door module that separates compartments in an aircraft. Door locking system has locking element that is adapted to maintain door panel of door module in a closed position. Door locking system further includes first and second mechanisms that are adapted to release door panel from the closed position in a normal and an abnormal mode, respectively. Second mechanism is spatially segregated from and operates independently of first mechanism. Second mechanism includes locking element release actuator, pressure sensor, and controller that directs locking element release actuator to act on locking element when pressure sensor detects a difference in pressure between the compartments that exceeds a predetermined threshold.
