This researchhas been conducted to perform a model for ballistics and propulsion specifications or characteristics of a monopropellant Propulsion system. The specifications such as total impulse, thrust, mass flow rate, specific impulse, characteristic velocity and total weight of consumed propellant are important in propulsion performance determination. Among 31th experimental hot tests of monopropellant thruster, the 20th number of tests are accepted. These experimental test data are recorded in the four environment constrains. By using the accepted experimental data, the important ballistic and propulsion characteristic can be derived. The variation of characteristic parameters versus the catalyst bed pressure, have been studied. Also, the variation of these parameters versus the Hydrogen peroxide concentrations, have been investigated. By analyzing the behaviors of characteristic parameter variations, the performance of the monopropellant propulsion system has been achieved.
