The invention relates to a separation device for a spacecraft or launcher. The separation device includes an inner housing divided into at least two portions locked to each other by a locking device in a locking position. The locking device is arranged to move between a locking position and a releasing position. The separation device includes an initiator including means for providing high pressure fluid to an expansion chamber when the separation device is switched from a locked state to a released state. The high pressure fluid in an expansion chamber moves the locking device from the locking position to the releasing position when the separation device is switched from the locked state to the released state. The separation device includes a dampening arrangement arranged to attenuate a peak load when the separation device is switched from the locked state to the released state.

An explosive bolt is provided for securing a brace in tension. The bolt includes a bar, a pair of explosives, a pair of detonators and a pair of anchors. The bar has opposing longitudinal ends and an outer thickness. Opposing bores extend inwardly from the longitudinal ends to corresponding depth ends. First and second notches reduce the thickness proximate to the corresponding depth ends. A center rod separates the notches from each other. Each explosive correspondingly inserts into a corresponding bore to a corresponding depth end. Each detonator correspondingly inserts into the corresponding bore. Each anchor secures the bar to the brace. In further embodiments, the longitudinal ends include helical male threads, and the anchors are nuts having helical female threads.

A trim panel assembly includes a trim panel configured to be removably connected to a pillar of a vehicle body structure. A connecting member includes a first part connected to the trim panel and a second part configured to be connected to the pillar. The first part is configured to be separable from the second part. A fastening member js connected between the first and second parts of the connecting member to limit a separation distance of the trim panel when the first part separates from the second part.

A low-shock separation device is characterized in that an internal locking structure is unlocked and a bolt is separated by operating a specific part of components thereof using high pressure that is generated by combustion of powder.

A sacrificial washer has a longitudinal central axis and comprises a cup and a cap. The cup includes a cup base wall extending transversely with respect to the axis, a cup radially outer wall extending outwardly away from the cup base wall, and a cup inner diameter. The cup includes a cap base wall extending transversely with respect to the axis and spaced axially away from the cup base wall, and a cap radially inner wall extending inwardly away from the cap base wall and having a cap inner diameter less than the cup inner diameter.

A separating device including a release ring able to slide along a segmented nut, the release ring being configured to move between a first position wherein the segments of the nut are retained around a fastening screw and a second position wherein the segments of the nut are released, said device being characterized in that the release ring is moreover configured to travel a determined distance between the second position and a third position wherein said ring is in contact with a damping element located between said ring and an annular shutter, the release ring not being in contact with the damping element between the second position and the third position.

A high-voltage battery quick release system for an electrified vehicle and related method for using same is provided. In one exemplary implementation, the high-voltage battery quick release system includes a first quick release switch that sends an activation signal indicative of a battery disconnect request. A mechanical decoupled is configured to mechanically decouple the high-voltage battery from the vehicle. An electrical decoupler is configured to electrically disconnect the high-voltage battery from the vehicle. A controller receives a signal from the first quick release switch and, responsive to the activation signal, (i) sends a signal to the mechanical decoupler that mechanically decouples the high-voltage battery from the vehicle and (ii) electrically disconnects the high-voltage battery from the vehicle.

An active bolt release arrangement includes a nut having nut portions adapted for radial movement, a sleeve part encircling the nut and having contact portions in contact with the nut portions in order to prevent the nut portions from radial movement, and a pyrotechnical actuator. The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement.
