セパレーションナットによる低衝撃無火薬分離機構の開発

抄録

A low-cost, lightweight, high-stiffness and low-shock separation mechanism using separation nuts was developed. This simple and easily manufactured mechanism, which consists of separation nuts, a polycarbonate band, nichrome burn wire, and connecting bolts, is non-explosive; thus, the separation shock is extremely small. The mechanism is intended for a non-pyro, non-explosive rocket using hybrid rocket engine, which does not use explosive fuel. In addition, by virtue of it being simple, low-cost, easily manufactured, lightweight, high stiffness and low-shock, the mechanism can also be used for micro- and nano-satellites. The design, development test, and launch test of the mechanism are reported.
