Embodiment

[0056] This embodiment provides a test device for ground release and recovery of tethered satellites, a schematic diagram of an axonometric view of the overall structure (see figure 1 ), including cable mechanism 2 (see figure 2 ), tether winding mechanism 9 (see image 3 ), tension detection mechanism and rope length detection mechanism 4 (see Figure 4 ), output tether angle detection and control mechanism 5 (see Figure 5 ), outer casing 3 (see Figure 6 ), bottom substrate 6, side cover 1. The outer shell is semi-cylindrical with varying diameters, the bottom of the outer shell and the bottom base plate are fixed together, and the sides of the bottom base plate and the outer shell are sealed by a side cover; The inner surface of the outer casing is provided with a ribbed plate, which can ensure the strength of the outer casing, and the inside of the outer casing is closely attached to the above-mentioned mechanism, so that the volume of the device is minimized.

Abstract

The invention relates to a test device for tethered satellite ground release and recovery. The test device for tethered satellite ground release and recovery comprises a tether winding mechanism, a wire arranging mechanism, a tension detection mechanism, a tether length detection mechanism, an output tether angle detection and control mechanism and a shell. The test device for tethered satellite ground release and recovery can be used for a research test on release and recovery dynamic characteristics of a ground tethered satellite, not only can measure and control the tension of a tether and complete tether length measurement of child satellite release and recovery, but also can measure and control the attitude entrance angle of the tether, carry out corresponding feedback control on the output angle of the tether, and control the attitude entrance angle, and can adjust the attitude entrance angle, so that release and recovery of the satellite are more controllable. The test device for tethered satellite ground release and recovery has the advantages that the structure is simple and clear, the tether path is clear and smooth, and the problems that the tether slips in the releasing and recovery process and catastrophic winding occurs in the tether due to loosening of the tether are solved.

Description

technical field [0001] The invention relates to the technical field of space tethered satellite system research, in particular to a test device for ground release and recovery of tethered satellites. Background technique [0002] As humans go deeper and deeper into outer space, there are more and more orbital junk. Many experiments and work in space need to use the tethered satellite system, and in it, the release of the tether and its recovery Many problems that may be encountered during the process have always been the object of research. Although the research on the space tether satellite system by various countries and international organizations has been carried out several years ago, the release of the tether is still a topic worth studying. question. After investigation, it is found that the existing devices for releasing and recovering tethered satellites still have some deficiencies, such as only measuring the angle of entry of the attitude but not adding an attitu...
