摘要:
An energy absorbing restraint device for a clamp system (100) is disclosed. The clamp system can include a releasable clamp (102) having first and second ends, a securing mechanism (108) connecting the ends and facilitating clamping and release of the clamp, and a restraint device (110) for containing the clamp after release. An energy absorbing member (112) supported about the restraint device can be configured to interface with the releasable clamp to dissipate the impact energy of the releasable clamp and decrease the magnitude of impact shock about the restraint device as created by the release of the clamp.

There is disclosed a Payload Ejection System (PES) able to store any set of payloads for launch and eject that set of payloads at a controlled speed with a low tumble rate while accommodating any offset centre of mass within a restricted volume. The need for ballasting or balancing is eliminated thus freeing up the design space for these payloads. Insensitivity to centre of mass location is enabled by the use of a deployment hinge assembly arrangement which uses two or more non-parallel folding hinge arrangements that allow for linear motion of the output link in one direction while restricting the motion all other directions. One embodiment of the current PES concept uses four (4) hinge panel assemblies, selected to provide optimal stiffness around the entire mechanism. The stiffness of the PES is integral to managing offset centre-of-mass locations by allowing the mechanism to translate the effective force vector to the center of mass location.
摘要:
The method and the device according to the invention allow two elements (1, 2) that are fixed to one another by two respective connecting plates (10, 20) belonging to the first element (1) and to the second element (2) to be separated linearly. The connecting and separating means are combined and consist of a layer (30). The connecting means consist of brazing, adhesive or resin, while the separating means consist of thermite. All of these elements can also be laid in layers. Electrically triggering this assembly (30) causes it to heat up quickly and locally and therefore allows the two elements (1, 2) to be separated. Application to the separation of two stages of an aeronautical launcher.

The method and the device according to the invention allow two elements (1, 2) that are fixed to one another by two respective connecting surfaces (10, 20) belonging to the two elements (1, 2) to be separated linearly. The connecting layer (30) is placed between the two connecting pieces (10, 20). Thermite (15) is used to make this layer of connecting means (30) melt. This thermite may be positioned on the other side of the first connecting piece (10) towards the first element (1), a heat shield plate (17) completing this setup. The thermite may also be placed in groves made on the connecting surface (22) of the second connecting plate (20) so as to be in direct contact with the layer of connecting means (30). Application to the separation of two stages of an aeronautical launcher.

Die Erfindung beschreibt eine Vorrichtung zum nicht-explosiven Aktuieren einer Komponente, insbesondere einer Raumfahrtkomponente. Diese umfasst ein Gehäuse (10) sowie einen zentral in dem Gehäuse (10) angeordneten Bolzen (20). Der Bolzen (20) ist zwischen einer ersten Position, in der ein äußerer Abschnitt (23) des Bolzens (20) in Bezug auf das Gehäuse (10) außerhalb des Gehäuses (10) angeordnet ist, und einer zweiten Position, in der der äußere Abschnitt (23) des Bolzens (20) innerhalb des Gehäuses (10) angeordnet ist, bewegbar. Die Komponente umfasst weiterhin eine Feder (30), die zwischen dem Gehäuse (10) und dem Bolzen (20) angeordnet ist. Eine, zwischen einer ersten und einer zweiten Stellung, drehbar in dem Gehäuse (10) angeordnete Aktuatorhülse (40) umfasst einen als Bahnkurve (BK) ausgebildeten Führungsabschnitt (41), entlang dem der Bolzen (20) während einer Drehung der Aktuatorhülse (40) geführt wird.
摘要:
A coupling and separating device is provided which can reduce a separation impact when separating a launch vehicle and a structure. The coupling and separating device is provided with a clamp band 6 which has blocks 3 and a strap 2, and a coupling section 4. The block 3 engages an installation member 20 of the launch vehicle and the structure 20 installed on the installation member 20. The strap 2 maintains the block 3 from outside. The coupling section 4 couples or separates the end sections 2a of the strap 2. The strap 2 is formed of shape memory alloy and is provided with a stretching section 11 which stretches through heating.

Device (1) for the restraint and release of a deployable body mounted on a support structure, the device (1) being operable between a stowed condition and a released condition, and comprising: - a pair of subassemblies (2, 3), each for being attached to either the deployable body or the support structure, these subassemblies (2, 3) comprising mating surfaces which interlock with one another in the stowed condition to substantially prevent lateral movement of the deployable body relative to the support structure; - a releasable tensioned element (5) which is connected to both of the subassemblies (2, 3), exerting a compressive pre-load action on the said subassemblies (2, 3) that keep them together; - a force measurement system (6) that allows monitoring the cited compressive pre-load action applied; - a releasing device (7) for releasing the cited pre-load, allowing the free separation of the subassemblies (2, 3); - further comprising a tensioning mechanism embedded in the device (1) such that it applies a substantially pure-tension pre-load to the releasable tensioned element (5), - and further comprising substantial mechanical spherical articulation capability, guaranteeing tilt misalignment adjustment of the stowed body relative to the support structure and the reduced hyperstaticity of body to support structure restriction, by substantially cancelling the moments exchange among them.
摘要:
The invention relates to a device (12) for linear separation of a first part (2) and a second part (4). The first part is linearly connected to the second part (4). The device comprises a heat source (12) applied to the first part (2), which applies a heat stimulus to the first part (2) such as to separate the first part (2) from the second part (4) by thermal deformation of the first part (2).
