In this article the Propellant Utilization system (PU) has been simulated. The objective of this system is to adjust the consumption ratio of the propellants in order to ensure the minimum propellant residuals at engine’s shutdown phase. Using the PU system, the orbital or range and also the payload capabilities of missiles or launch vehicles will be enhanced. In this article, after studying and simulation of the PU system, the necessity of using such system is compared with a missile without the PU system. At the end of this paper it is proven that using PU system on a desired missile has enhanced its range up to 7 percent and has also reduced the propellant residuals up to 25 percent.
