Payload Mass Fraction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Payload Mass Fraction = Payload Mass/(Propellant Mass+Structural Mass)
λ = m_d/(m_p+m_s)
This formula uses 4 Variables

Variables Used

Payload Mass Fraction - Payload Mass Fraction quantifies the portion of a rocket's total mass that is attributed to the payload.
Payload Mass - (Measured in Kilogram) - Payload Mass is the mass of the payload that the rocket carries, such as satellites, instruments, or other cargo.
Propellant Mass - (Measured in Kilogram) - Propellant Mass refers to the total mass of propellant used in a propulsion system.
Structural Mass - (Measured in Kilogram) - Structural Mass is the mass of the rocket's structure, including tanks, engines, guidance systems, and other hardware.

STEP 1: Convert Input(s) to Base Unit

Payload Mass: 34 Kilogram --> 34 Kilogram No Conversion Required
Propellant Mass: 13 Kilogram --> 13 Kilogram No Conversion Required
Structural Mass: 44 Kilogram --> 44 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

λ = m_d/(m_p+m_s) --> 34/(13+44)

Evaluating ... ...

λ = 0.596491228070175

STEP 3: Convert Result to Output's Unit

0.596491228070175 --> No Conversion Required

FINAL ANSWER

0.596491228070175 ≈ 0.596491 <-- Payload Mass Fraction
