Abstract: A device used for providing dynamic isolation and damping of dynamic vibrations, in a passive way, originated in the launch vehicle of a space shuttle and reaching the payload or satellite. The device comprises a plurality of identical elementary unit elements, such that the device is designed in a modular way, allowing the individual modularity of each of the elementary unit elements. Each of the elementary unit elements is tailored and designed individually, and the complete device can be designed for each particular application and payload needed as a function of each of the elementary unit elements allowing an easy design and lower costs, for a wide range of payload applications. Each elementary unit element comprises a spring component and a damping component, such that the functionalities provided for each component are separated and can be individually tailored, thus providing a device having a wider range of adaptation capabilities.

Abstract: A device for the restraint and release of a deployable body mounted on a support structure, the device being operable between a stowed condition and a released condition, and having: a pair of subassemblies, each for being attached to either the deployable body or the support structure, these subassemblies having 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 which is connected to both of the subassemblies, exerting a compressive pre-load action on the said subassemblies that keep them together; a force measurement system that allows monitoring the cited compressive pre-load action applied; a releasing device for releasing the cited pre-load, allowing the free separation of the subassemblies; further being provided with a tensioning mechanism embedded in the device such that it applies a substantially pure-tension pre-load to the releasable tension

Abstract: A process for improving the reflectivity of reflective surfaces made of a composite. The process includes laminating a layer of metalized plastic on at least one layer of composite, bonding the metalized plastic to a substrate in a preimprgenated state; cutting strips or patterns of an assembly of the layer of composite and the layer of metalized plastic; laminating strips or patterns of the assembly as a first layer on a molding jig; adding additional composite layers to the first layer; preparing a vacuum and curing bag; introducing the assembly in an autoclave; performing a curing cycle, bonding the layer of metalized plastic to the rest of the substrate by polymerization of a resin in the composite.

Abstract: A launcher and satellite connection-separation apparatus for launching and satellite vehicles has a band-clamp assembly of a band with an inner channel in which clamps are located in a sliding manner for application to rings interfacing between the vehicles, and a union-separation device on ends of the band for radially tightening the band and controlling opening of the band in first and second phases such that the ends of the band shift in contact with the rings for dissipating by friction elastic energy corresponding to the tightening of the band and separate from the rings until reaching a parking position.

Abstract: The invention relates to a process for improving the reflectivity of reflective surfaces (1) of antennas, said reflective surfaces (1) being made of a composite, comprising at least one layer of composite (2), characterized in that it comprises the following steps: a) laminating a layer of plastic (3) comprising a metallization layer (4) on the at least one layer of composite (2), bonding the metallization layer (4) to the substrate of the layer of composite (2) in its preimpregnated state by means of the resin itself of the composite; b) cutting the assembly of the layer of composite (2) and the layer of plastic (3) comprising a metallization layer (4); c) forming strips or patterns with a determined shape from the assembly formed by the layer of composite (2) and the layer of plastic (3) comprising a metallization layer (4) of step b); d) laminating the strips or patterns of step c) as a first layer on a molding jig; e) preparing the vacuum and curing bag; f) introducing in the autoclave; g) performing t
