Propellant utilization involves efficiently using the propellant (fuel and oxidizer) of a rocket to achieve a specific mission objective, typically delivering a payload to a desired destination.
Where:
- Propellant utilization (PU) expresses the efficiency of propellant usage as a percentage.
- The mass of the payload (the payload carried by the rocket) constitutes
- is the mass of the propellant (the fuel and oxidizer used by the rocket)
