Definitions
- the present invention relates to a connection / separation device for satellites that have to be separated during the flight, for example, from a shuttle or from a satellite dispenser.
- EP 0768241 Al Another system for joining and separating satellites is described in EP 0768241 Al It comprises a fixing piece that is screwed to the upper ring of the launch rocket adapter, a tensioning band consisting of a two-piece metal strap, curved metal fixing parts of the satellite that have a thin-walled cylindrical body with a metal pivot shaft in its lower part formed by several lugs and that rest with its upper part on the lower hoop of the satellite surrounding and tightening it, and some clamping cams that each two axes of rotation, one coinciding with that of said metal parts and the other shared with said piece.
- the objective of this system is to simplify the subjection of the satellite to the rocket launcher and its release when entering orbit.
- EP 0905022 A1 describes a system for fixing and separating satellites comprising an open ring or metal band that has a channel formed in its internal perimeter in which jaws that can slide in said channel are discontinuously integrated, two end pieces attached to the ends of said ring, a bolt tensioner that joins both end pieces and three retention brackets of! ring attached to the structure of a satellite launcher.
- EP 1944237 A1 refers to an apparatus for connecting / separating a shuttle vehicle and a satellite, comprising a band with an inner channel in e! that a plurality of jaws are slidably located, which is applied on rings that constitute the interface between the two vehicles.
- the apparatus also comprises means for radially tensioning the assembly comprising the band and jaws, and a device for joining / separating its ends, which, together with locking and unlocking means, includes a mechanism that allows controlled opening of the band in two phases: a first phase in which the ends move while keeping in contact with the rings, thus dissipating by friction the elastic energy corresponding to the tensioning of the band; and a second phase in which the band separates from the rings until it reaches a parking position.
- connection / separation systems with tensioning band are indicated when the load per unit of length to be transmitted is high.
- the relatively high weight of the connection / separation system It can cause problems (for example, the available mass for the satellite itself may be reduced).
- the object of the invention is to provide a connection / separation device for elements of a spacecraft or of a shuttle that is light, allowing in turn to obtain a homogeneous tension over the entire perimeter of the connection interface between the two separable elements.
- the invention provides a connection-separation device for separating satellites from shuttles or satellite dispensers comprising:
- connection-separation device of the invention makes it possible to tension evenly around the perimeter of the connection interface between the two separable elements, and in the absence of additional elements (such as an external band) a lighter system is achieved.
- the proposed solution is very suitable when the weight is a conditioning factor (for example, for missions with microsatellites and mini-satellites).
- Another advantage of the invention is that, when the load is distributed throughout the perimeter of the interface, point loads are avoided and, therefore, local reinforcements in the structure, optimizing its weight.
- Another advantage is the reduction of the shock because the release mechanism forces a slow opening of the band compared to a traditional system.
- Figure 1 shows a view of a band-jaw assembly of the prior art with a joint-separating mechanism of the ends of the band.
- Figure 2 is a perspective view of the connection / separation device of the invention.
- Figure 3 is a perspective view of the connection / separation device of the invention mounted on the rings that form the connection interface between the two separable elements.
- Figure 4 is a detailed view of! connection / separation device of the invention on the rings that form the connection interface between the two separable elements.
- Figure 5 is a detail view of one end of a jaw of! connection-separation device of the invention.
- Figure 6 is a perspective view of a release mechanism of the connection-separation device of the invention.
- Figure 7 is a perspective view of the release mechanism of Figure 8 mounted on the two corresponding jaws of the connection-separation device of the invention. Detailed description of the invention
- Figure 1 shows a band-jaw assembly of the prior art with a joint-separating mechanism of the ends of the band.
- this device has an outer band with an inner channel in which a plurality of jaws are placed.
- Said device corresponds to e! Low impact / heavy load separation system of the applicant, known as LPSS (Low-shock / Large Pay! oad Separation System), from! EP 1944237 A1, suitable for heavy loads.
- LPSS Low impact / heavy load separation system of the applicant
- FIG. 2 represents a perspective view of! connection / separation device 1 of the invention. It is noted that the device comprises a plurality of circumferentially aligned jaws 2, 2 ', the number of which will depend on the diameter of the interface. As best seen in figures 2, 3 and 4, these jaws 2, 2 'are coupling on their face internal on rings 6, 7 of the separable elements that constitute the connection interface between the two separable elements.
- the connection / separation device 1 of the invention also comprises a release mechanism 3 that connects two of the jaws 2 'by one of the ends of said jaws 2'.
- the two jaws 2 'connected by the release mechanism 3 comprise a projection 4 protruding from its outer face at its opposite end to the connecting end with the release mechanism 3.
- the remaining jaws 2 have, at each of their adjacent ends to the jaws 2, 2 'adjacent, a projection 4 protruding from its outer face.
- a projection 4 protruding from its outer face.
- the projections 4 of the ends of the jaws 2 (also located at one of the ends of the jaws 2 ') have a through hole 8.
- the joining means 5 implemented in said embodiment are screw and nut systems arranged tangenically, which pass through the through holes 8 of the protrusions 4 to connect the corresponding adjacent jaws 2, 2 '. These joining means 5 allow the connection / separation device 1 of the invention to be tensioned conveniently.
- Figure 3 shows a device 9 for receiving the jaws 2, 2 'when the connection / separation device 1 of the invention is released.
- Said device 9 is only connected to the ring 7 of the separable elements, and comprises a housing or re-reception that receives the jaws 2, 2 'when it falls.
- Several of these devices 9 are angularly separated from each other to receive the jaws 2, 2 '.
- connection / separation device 1 of the invention In order to make the connection / separation device 1 of the invention more rigid, it is possible to insert additional elements, as fillers (see Figure 3) between the projections 4 of the ends of the jaws 2, 2 'adjacent, thus providing continuity and a general shape closer to a hoop.
- Said filling elements may be of a viscoelastic material.
- the jaws 2, 2 'can have an internally hollow cross-section, which allows lightening e! set weight For elio they can be manufactured using additive layered manufacturing technologies (ALM, Additive Layer Manufacturing).
- the jaws 2, 2 'can comprise an area with holes as a grid (see Figures 2, 3 and 5), which also allows lightening the weight of the assembly.
- Figure 7 shows the release mechanism 3, located between the jaws 2 '. You can make use of a material with shape memory (SMA, or Shape Memory Alloy) in the release mechanism 3, so that when you apply an intensity it warms and changes its crystalline state, which allows to open the mechanism of release 3,
- SMA shape memory
- Release mechanism 3 allows controlled release to reduce! shock generated during the deployment of the connection / separation device 1 of the invention itself.
- the shock is less than in the existing low shock bands.
- the release mechanism 3 (see Figures 2, 6 and 7) is composed of a release element in itself 1 1 which can be pyrotechnic or non-explosive (SMA, fushing, etc.), which holds a bolt 13 that it maintains a bridge 12 in position when the load of the bolt 13 in the lower ring 7 reacts through a runner 14.
- the bridge 12 carries two male conical contacts that are housed in the corresponding conical holes of the jaws 2 '( Figure 7) .
- the tension of the connection / separation device 1 slowly relaxes through the sliding between the male cones of the bridge 12 and female of the jaws 2, thereby obtaining a passive shock reduction system.
- connection / separation device 1 of the invention has a significant reduction in mass with respect to previous devices.
- a band of diameter 1668 mm made with the system known as LPSS mentioned above weighs about 23.2 kg, while weighing 2.7 kg with the system of the invention.
- the device of the invention would weigh approximately 750 g. Elio makes it a very convenient system when a high load capacity is not necessary, as, for example, for microsatellites and mini-satellites. It is especially applicable to these types of missions:
