Study on the penetration characteristics of conical harpoon on rotating space debris

The purpose of this paper is to study active removal of rotating space debris in space, a conical harpoon was used to carry out penetration experiments on a single-axis rotating 2A12 aluminum alloy target plate at 6 degrees / s, 12 degrees / s and 18 degrees / s, respectively. The velocity change curve and kinetic energy change curve of the harpoon were established. The results show that the rotation velocity of the 2A12 aluminum alloy target has little effect on the velocity change of the harpoon after the harpoon penetrates the 2A12 aluminum alloy target with different rotation speeds. Under the same initial kinetic energy E = 2738.78 J, the velocity of kinetic energy attenuation of harpoons with different initial velocities in the process of penetrating the aluminum alloy target plate is different. According to the research, the velocity of the kinetic energy attenuation of the harpoon can be arranged according to the initial velocity, as follows: 30.73 m/ s > 28.38 m/s > 26.50 m/s > 24.95 m/s, which means that the greater the initial velocity, the faster the kinetic energy attenuation of the harpoon.
