PURPOSE:To raise the launching speed of a missile by providing a supply device for supplying an actuation fluid not including an oxidizing agent, a nozzle communicating between opposite surface sides of a piston, and a mechanism for closing the nozzle only at a stop position of the piston. CONSTITUTION:An actuation fluid chamber 20 is filled with an actuation fluid not involving an oxidizing agent by an actuation fluid supply device 22. Then, once electric power is supplied to a plasma generation device 29, plasma is generated in a reaction chamber 15 a piston 18 is actuated, and a nozzle 26 is opened to supply the actuation fluid to the reaction chamber 16. The piston 16 is further pushed toward the fluid chamber 20 side by pressure of gas which is evaporated, decomposed, and produced by the plasma hitting the actuation fluid. Hereby, the actuation fluid can be supplied stably to the reaction chamber 16, so that au actuation fluid not involving an oxidizing agent is made useable. This assures light production gas. Therefore, a missile can be increased in its launching speed. |
