In this study, we described the Pyrovalve used in the propulsion system. It is very important to reduce Pyrovalve-debris as far as possible because Pyrovalve is a pyrotechnic device for controlling fuel and air line of propulsion system. So we focused on redesigning to reduce debris through several analyses and tests.
