How to Calculate Structural Mass Fraction?
Structural Mass Fraction calculator uses Structural Mass Fraction = Structural Mass/(Propellant Mass+Structural Mass) to calculate the Structural Mass Fraction, Structural Mass Fraction is a parameter used in rocket engineering to quantify the proportion of a rocket's total mass attributed to its structure relative to the total mass of the structure plus the propellant, it is defined as the ratio of the structural mass to the sum of the structural mass and the propellant mass. Structural Mass Fraction is denoted by σ symbol.
How to calculate Structural Mass Fraction using this online calculator? To use this online calculator for Structural Mass Fraction, enter Structural Mass (m_{s}) & Propellant Mass (m_{p}) and hit the calculate button. Here is how the Structural Mass Fraction calculation can be explained with given input values -> 0.77193 = 44/(13+44).
