STEP 0: Pre-Calculation Summary

Formula Used

Propellant Mass Fraction = Propellant Mass/Initial Mass
ζ = m_p/m₀
This formula uses 3 Variables

Variables Used

Propellant Mass Fraction - Propellant Mass Fraction refers to the ratio of the mass of the propellant (fuel and oxidizer) to the total initial mass of the vehicle.
Propellant Mass - (Measured in Kilogram) - Propellant Mass refers to the total mass of propellant used in a propulsion system.
Initial Mass - (Measured in Kilogram) - Initial Mass often refers to the mass of a spacecraft or rocket at the start of a mission, including all components such as payload, structure, propellant, and any other necessary equipment.
