This research discuss about the effect of simultaneous usage of Propellant Utilization (PU) system and Flight Apparent Velocity Regulation (AVR) system. These systems were used for sending OBC commands to engine for adapting the engine working regime with flight conditions and fame to active control systems. Each of PU and AVR systems has an effective roll in access to final parameters such as mass and velocity at the end of active phase and simultaneous usage of these systems lead to increase the range accuracy and payload mass. We study these effects on final parameters in this paper. Therefore, with dynamic simulation of liquid propellant engine in during of active phase in flight simulator, sending commands of these systems to change the engine working regime is provided. For a specific mission results show that with working of the PU, range increased and presence of AVR, is assist to reach this range in front of disturbance during the flight. Another main result of this research is, increasing of payload mass for a specific mission with simultaneous usage of PU and AVR systems.
