A safe and reliable multi-component projectile enables cost effective manufacturing and assembly of the projectile. Major components of the projectile are joined by a plurality of shear pins interfacing with scalloped geometry of the components. The components are then held together by forcibly joining them using a hybrid annular-cantilevered snap fit joint. The tooth and groove arrangement exists where the teeth are at the end of a spring-leaf like feature of one of the mating parts and the groove is located on the opposite mating part.

The system (S) to separate at least two mechanical elements (E1, E2), comprises a holding device comprising a connecting screw integral with a mechanical element (E1) and held by a nut segmented in portions (4n) arranged between the connecting screw and an outer envelope integral with the other mechanical element (E2), the system (S) comprising a force generator generating a thrust force (F) in a longitudinal direction (X-X) and comprising an energy accumulator comprising a sealed chamber with a colloid of a porous matrix and liquid, the chamber deforming in the longitudinal direction (X-X) to adapt to the change from a compressed to a decompressed state in order to generate the force (F), and an activatable actuating element to, either apply a predetermined pressure to the chamber to keep the colloid in the compressed state, or not apply the predetermined pressure to allow the change in state of the colloid.

A vessel, such as a rocket motor tube, comprised of an insert, and a joint that allows the insert to decouple from the vessel to relieve pressure when subjected to excessive temperatures and/or a predetermined temperature or temperature range.

A cam-lock fastening system is designed to accommodate a tolerance stackup to fasten a pair of rigid structures. A spring allows some longitudinal motion of the pin that would not be accommodated by the rigid structures or metal cam-lock and pin. The spring-loaded pin is also suitably designed to produce a preloaded structural joint that is between specified minimum and maximum loads for any tolerance stackup that is within specification. The fastening of the structures requires no manual adjustment of the pin, and facilitates blind connection of a high-fidelity electrical connector. Further, the described cam-lock fastening system is designed for high performance applications requiring preload forces in the thousands of pounds per square inch.

A module separation mechanism, in particular for rockets, includes a cylindrical first body, a cylindrical second body, and a ring connecting the two bodies, The ring comprises at least one tension lock together with a cover. The first body comprises at least one radially mounted actuator that is adapted to eject the tension lock together with the cover from the ring in a manner to disengage the ring. The first body further comprises at least one ejecting member adapted to eject the second body from the first body. The outer surface of the ring together with the cover is faced with the outer surface of the first body and the second body.

A separation device includes: an outer case; a pillar-shaped separation member including an engaging portion; a support member including a swinging portion and an engageable portion, the swinging portion being swingably supported by the outer case, the engageable portion supporting the separation member; an inner case including a fitting hole restricting swinging of the support member; and an operation-enabling element, which supports the inner case and which is fusion-cut when an electric current is applied thereto. When the operation-enabling element is fusion-cut, the inner case is displaced, such that: the engageable portion of the support member detaches from the fitting hole; the swinging portion swings; and the engageable portion moves away from the engaging portion to release the separation member.

A separation system for separable elements of spacecraft and launchers includes an upper ring, a lower ring and a band with an inner channel which houses slidable clamps, which are applied against the upper ring and the lower ring that form the connection interface between the two separable elements. A device joins/separates the ends of the band, both the upper ring and the lower ring including an outer protruding element with a wedged section to be lodged in the clamps. The upper ring also has an inner protruding element with a wedged section that matches a channel shaped section in the lower ring, the lower ring also has an outer portion including the outer protruding element with a wedged section and the channel shaped section, the outer portion protruding from a main part of the lower ring and being spaced from it creating a groove.
