PROBLEM TO BE SOLVED: To suppress the generation of harmful waste such as a base and the like, and prevent the contamination of earth environment by using ammonium nitrate as oxidant, and using mixture of burnable metallic powder and burnable liquid with ammonium nitrate as a propellant so as to obtain engine thrust. SOLUTION: A cylindrical space 12 filled with liquid 11 such as water, hydraulic oil, and the like inside is formed in a cylindrical main body 10, and a combustion chamber 1 is formed in the cylindrical body 10. A nozzle 2 communicating with the combustion chamber 1 is formed on an end part of the cylindrical main body 10, an ignition body 13 is filled in the nozzle 2, a cylindrical body 3 for oxidant made of ammonium nitrate is formed, and a spiral longitudinal member 18 made of burnable metal is arranged in a burnable metallic powder 19 of the inside. Pressure of a burnable fluid 20 in the longitudinal cylindrical member 18 is boosted up in association with heat decomposition of ammonium nitrate of the cylindrical body 3 for oxidant at the time of combustion of the ignition body 13. When the burnable metallic powder 19 is burnt and the burnable fluid 20 is injected, the burnable metallic powder 19 is mixed with ammonium nitrate of the cylindrical body 3 for oxidant so as to obtain thrust by combustion of the burnable fluid 20. |
