Abstract
Systems and methods for determining bi-propellant volume and adjusting a mixture ratio are discussed herein. A controller can calculate an adjusted mixture ratio and command the rocket engine to implement the adjusted mixture ratio by opening or closing valves of the propellant tanks, which changes the volumetric flow rates of each of the propellants. The adjusted mixture ratio can be calculated by an algorithm based on sensed or calculated data associated with each propellant. The adjusted mixture ratio can be used to evenly deplete the propellants to reduce the amount of each propellant remaining after a mission and to improve propellant use, which allows for an increase in a non-propellant payload.
