Embodiment Construction

[0028] The present invention designs an integrated star-arrow separation structure, which is suitable for the star-arrow connection unlocking task where the separation nut is used as the pyrotechnic connection unlocking device. The mechanism design of the invention is simple and feasible, has high safety, and will not interfere with rockets and satellites. At the same time, the satellite-rocket separation structure has a simple interface with the carrier and the satellite structure, which is convenient for quick installation, and considers the spectrum of products, which is convenient for selection of various tasks.

[0029] see Figure 1 to Figure 4 As shown, the integrated design of the satellite-rocket separation structure of the present invention generally installs the satellite-rocket separation mechanism 100 at the exact center of the satellite base plate 20 for micro-satellites such as Pina satellites. One end of the satellite-rocket separation mechanism 100 is connect...

Abstract

The invention provides an integrally-designed satellite-rocket separation mechanism. The integrally-designed satellite-rocket separation mechanism comprises a satellite end separation base, a carrier end separation base, a release spring and a pyrotechnic separation nut, wherein the satellite end separation base is connected with a satellite bottom plate; the carrier end separation base is connected with a carrier; the release spring is accommodated in inner space of the carrier end separation base to provide elasticity between the satellite end separation base and the carrier end separation base; a connection screw rod of the pyrotechnic separation nut penetrates through insides of the carrier end separation base and the release spring to be connected with the satellite end separation base, and a nut body of the pyrotechnic separation nut is connected with the carrier end separation base. A satellite-rocket connection mechanism, the satellite-rocket separation mechanism and a satellite-rocket separation signal acquisition mechanism are integrated in one structure, the spring is accommodated in the separation base, the screw rod of the pyrotechnic separation nut penetrates through the carrier end separation base and the release spring, so that the design is simplified and compact, the occupied space is greatly reduced and the integrally-designed satellite-rocket separation mechanism is simpler and smaller than an existing separation mechanism.

Description

technical field [0001] The invention relates to the field of aerospace equipment, in particular to an integrated design of a satellite-rocket separation mechanism. Background technique [0002] At present, the mechanical interface between the satellite and the rocket has two connection forms: the explosive bolt connection type or the tape connection type. The separation mechanism of the explosion bolt connection type is composed of a separation spring and an explosion bolt. After the explosion bolt is unlocked, the satellite and the distributor are separated under the push of the separation spring. However, the explosion bolt and the separation spring of this separation mechanism are separately designed and installed on the satellite, which is bulky and complicated to install, and cannot meet the requirements of rapid installation. The tape connection type separation mechanism is composed of tape, non-polluting explosion bolts, V-shaped clamping blocks and other components....
