Roughly in 1990’s, the concern about lower cost, more environmental friendly and non-toxic propellants showed that hydrogen peroxide can become as an alternative propellant to hydrazine and nitrogen tetroxide for those applications where these propellants were unacceptable. From this issues, the theory and performance calculation of hydrogen peroxide monopropellant thruster are theory concerning about the thrust produced by the thruster and designing of the thruster based on the require thrust. Design and Development of the thruster must be verify by the thruster performance from LabVIEW to the manual calculation. The performance will be compared between the model design and the experiment. Still, the theory and performance calculations falls short of being a complete theory of fundamental monopropellant thruster. Here, experiment results were shown,due to the effect during experiment,repeated experiment were done. From this issue, list of the method for preparing the thruster before firing must be followed by the proper steps and precautions were explained.
