Abstract: A de-coupling mechanism includes a link slidably received in a link aperture of a bracket. A pin is slidably received in a pin bore of the link and a receiving bore of the bracket. A first block is connected to the bracket and includes an initiator receiving passage in communication with the pin bore. An initiator is positioned in the initiator receiving passage and retained against a connecting passage edge and oppositely contacts an end face of a cap connected to the first block. A second block connected to the bracket includes a longitudinal channel having a channel diameter larger than a pin diameter so the pin is freely displaceable into the longitudinal channel. An end face of a retaining cap is connected to a second block end wall. The retaining cap includes a stepped portion having a step diameter smaller than the channel diameter and the pin diameter.

Abstract: A deployable raceway harness assembly for use with a multi-stage rocket includes a first cable bundle configured to extend across a second stage of a multi-stage rocket from a guidance unit to a first stage of the rocket. The deployable raceway harness assembly includes a deployable raceway cover configured for detachable coupling with the multi-stage rocket. The deployable raceway cover extends over at least the first cable bundle and a second cable bundle. The first cable bundle is fastened to the deployable raceway cover. The second cable bundle is configured to extend from the guidance unit to the second stage and is shorter than the first cable bundle. An in-flight deployment mechanism is configured to detach the deployable raceway cover and the first cable bundle extending across the second stage from the multi-stage rocket in-flight leaving the second cable bundle extending to the second stage in place.

Abstract: The present invention relates to the field of store ejection from aircraft. More specifically it relates to cartridges used in ejector release units for stores. The invention aims to provide a cartridge that can be used in existing ejector release units that overcomes some of the problems (such as; only a one-time use, the need for cleaning of ejector units, the erosion of ejector units and the need for a holder to be used) of pyrotechnic or hot gas cartridges but without compromising performance. The present invention provides a cartridge for use in an ejector release unit, the cartridge comprising a gas chamber for containing gas under pressure, an outlet of the gas chamber for releasing the compressed gas to drive a release mechanism in the ejector release unit, and a release valve associated with the outlet and arranged to be operable to open the outlet upon activation of a firing pin of an ejector release unit. An ejector release unit containing such a cartridge or pair of cartridges is also provided.

Abstract: In accordance with one embodiment of the present disclosure, a method includes driving a piston by mechanically harnessing an explosion of energetic material contained in a cartridge. The method further includes releasing cleanser contained in the cartridge in response to the explosion of the energetic material.

Abstract: According to one embodiment, an ejection system for deploying a store includes a first cartridge actuated device coupled to a first release mechanism, a second cartridge actuated device coupled to a second release mechanism, and a controller circuit coupled to the first and second cartridge actuated devices. The first and second release mechanisms are configured to eject the store away from a vehicle. The controller circuit is operable to detonate the second cartridge actuated device at a specified period of time after the first cartridge actuated device is detonated.

Abstract: A pyrotechnically-ruptureable composite structural component, intended to transmit forces between first and second structural elements, has an elongate pyrotechnic detonation separation component incorporated in the structural component for breaking the structural component and separating the first and second elements. The structural component has a first part in which the pyrotechnic separation component is incorporated and which is able to be connected to the first element, and a second part that connects to the second element. The first and second parts are rigidly assembled via their free ends, which are the opposite ends to the first and second elements respectively. The rigid assembly has a damper arranged between the free ends of the first and second elements so as to damp a detonation shock propagating to the free end of the first part when the pyrotechnic separation component is detonated.

Abstract: A cable restraint/deployment mechanism is disclosed for deploying an object in space from a spacecraft. To deploy the object, the cable restraint/deployment mechanism cuts a cable attached to the spacecraft and the object. For example, a spacecraft may include a solar panel array that is restrained by the spacecraft in a stowed form through the use of a wire rope cable. The cable may be affixed at one end to a deployable object. The other end of the cable is affixed to the spacecraft through a cutting mechanism, such as a pyrotechnically actuated cutting device. The cutting mechanism cuts the cable at a swaged sleeve of the cable. The swaged sleeve of the cable substantially prevents splaying of the cable and cutting debris.

Abstract: Apparatus for separating aerodynamic objects from an aerodynamic vehicle includes a first element, aerodynamically configured to create nose-down pitching moment, mounted to the object surface, a second element mounted to the first element and projecting into an oncoming airstream such that when enabled, the passing air tears the apparatus from the surface which otherwise supports it. The first element is a body designed to be conformal with the object surface to which it is mounted, and includes a forward end projecting into the oncoming airstream and a rearward end, and is secured to said object surface at the rearward end thereof. A flexible gasket is interposed between the first element and the object surface. The second element comprises a forward end directed toward the oncoming airstream and a rearward end, with the second element being mounted to the first element at the rearward end of the second element.

Abstract: A release fitting for releasably holding at least one line to at least one item, the release fitting having a first body part, a second body part, and a third body part, the first and second body parts pivotably secured to the third body part, a bolt with a first bolt portion connected to a first portion of the first body part and a second bolt portion connected to a first portion of the second body part, at least one pin suitable for attaching thereto the at least one line, the first body part having a recess for releasably receiving an end of the pin, the bolt initially holding apart the first portion of the first body part and the first portion of the second body part to thereby maintain a second pin end in the recess, the third body part connected to the at least one item, bolt cutter apparatus for selectively cutting the bolt to release the at least one line from the pin.
