Abstract

Various types of pyrotechnic devices are widely used in aerospace engineering, the ignition of pyrotechnic devices will induce shock load on aerospace structure, and excite its modal response. For sufficient lock stiffness margin, satellite deployable antennas usually include several HLD (hold and release) mechanisms, different ignition orders of the pyrotechnic devices will cause different shock response, and therefore optimization should be carried on to reduce the potential damages on antenna structure. The release strategy optimization is conducted on a satellite deployable antenna contains three HLD mechanisms, and the optimization result show that, the acceleration magnitude of shock response in key area is reduced sharply, which reveals the probable destroy possibility introduced by shock environment is effectively controlled. The feasibility and effectiveness of the proposed release strategy optimization method was validated by flight experiences.
