The Tsiolkovsky Rocket Equation Formula
The Rocket Equation, also known as the Tsiolkovsky Rocket Equation, is a fundamental principle in astronautics that calculates the change in velocity (delta-v or Δv) a rocket can achieve. It's expressed as:
Δv = ve · ln(m0 / mf)
Where:
- Δv (delta-v) = The maximum change in velocity of the vehicle (m/s)
- ve = Effective exhaust velocity of the propellant (m/s)
- ln = Natural logarithm function
- m0 = Initial total mass (wet mass, rocket + propellant + payload) (kg)
- mf = Final total mass (dry mass, rocket + payload after propellant is expended) (kg)
