To provide a one-component thruster which can be easily manufactured and is advantageous for the reliability and cost, can prevent the catalyst particles from being collapsed or abraded locally or wholly in the catalyst layer, resulting in allowing the control of trouble occurrence such as efficiency degradation of hydrazine degradation reaction or decrease of thrust, and is excellent in durability, and to provide a method of operation thereof.
A chamber 5 including an injector 3, and being filled with a catalyst layer 4 decomposing hydrazine introduced through this injector 3 to generate the decomposed gas, a nozzle 6 to obtain thrust by ejecting the decomposed gas generated in this chamber 5 are included, and a gas circulating mechanism 10 for storing one part of the decomposed gas generated in the chamber 5, and injecting this stored decomposed gas to the portion located near the injector 3 of the catalyst layer 4 in the chamber 5 is also included.
