Description
Technical Field
The invention relates to a satellite and rocket adapter, in particular to a satellite and rocket adapter capable of being synchronously released by multi-point compression.
Background
In the aerospace field, the connection and release of payloads to vehicles is widespread, such as multi-rocket stages and stages, satellite and launch vehicles, satellite and spacecraft, solar wing and spacecraft, deployment antennas and spacecraft, and the like. The mode that adopts at present has, the device based on initiating explosive device connects and releases, and the initiating explosive device that uses connects and release has based on explosion bolt compresses tightly the seat, based on explosion bolt or the band of initiating explosive device cutter, based on the compression seat of initiating explosive device separation nut, based on the compression seat of initiating explosive device cutter etc. these compression release's common characteristics are bearing the connecting force, in order to guarantee the connection rigidity, the connecting force often reaches thousands or even tens of thousands N, need utilize the huge explosion impact force of gunpowder to destroy initiating explosive device itself and realize the unblock, the explosion impact when unblock easily causes the damage to the spacecraft, disposable, the cost is higher. The device also comprises a compression release device adopting a non-initiating explosive device mode, such as CN200910122846.1, and a space linkage compression release mechanism, wherein the compression release device comprises a compression cap, a compression rod, a shell, a spring cover, a spring support, a locking connecting rod, a U-shaped connecting rod, a straight connecting rod, a connecting shaft pin, a fixed pin shaft, a rope connector and a linkage rope. When the compression release mechanism is in an unlocking state, the U-shaped connecting rod and the straight connecting rod leave the horizontal position, namely the dead point position under the action of the elastic force of the spring, so that the spring is in an extending state. Because space linkage compresses tightly release mechanism has a dead point, needs big unblock power in the unblock in-process, and when the locking lever compresses tightly the clamp bar in addition, because the area of compressing tightly between locking lever and the clamp bar is little, so be difficult to bear the unblock of heavy load operating mode.
When the effective load is separated, the effective load is required to be stably pushed away from the carrier, the currently adopted mode is that an ejection device for directly pushing the load is based on a single spring or a spring array, in order to ensure the stable posture of the load in the ejection process, the parameters of the spring or the position of a load interface are required to be balanced according to the position of the mass center of the load, so that the resultant moment generated by the ejection force on the satellite is zero, if the mass center of the load is not in the geometric center of the spring array, the position of the mass center is generally required to be adjusted by installing a balancing weight, and the load quality is increased. The device is also provided with an ejection device which restrains the freedom degree of the effective load through a guide rail, such as 201510777309.6, and a modularized low-impact linkage type microsatellite separation device, when the separation device is in a separation state, 4 pressure springs are used for pushing the guide rods, and the 4 guide rods are used for respectively pushing the buckling surfaces on the satellites to push the satellites to be separated from the base. The proposal ensures the gesture though the guide rail, if the ejection force is larger to the resultant moment generated by the satellite, the risk of satellite blocking on the guide rail or unsmooth unlocking or insufficient initial ejection speed still exists, thus the accurate measurement of the load mass center is required as well, and the elastic accuracy of each spring is strictly required. For the ejection device without the guide rail, in order to stabilize the load gesture in the ejection process, the thrust overload centroid is required, so that strict requirements are imposed on the thrust-deformation curve of each spring.
