Rocket Equation Nasıl Hesaplanır?
learn.whatIsHeading
The rocket equation (Tsiolkovsky) relates rocket velocity change to exhaust velocity and mass ratio. It's fundamental to space mission planning and launch vehicle design.
Formül
The calculator applies ΔV = v_e × ln(m_initial / m_final)
Adım Adım Kılavuz
- 1Enter initial mass, final mass, and exhaust velocity
- 2The calculator applies ΔV = v_e × ln(m_initial / m_final)
- 3Results show achievable velocity change
Çözümlü Örnekler
Giriş
v_e = 4000 m/s, m_initial = 100 tonnes, m_final = 10 tonnes
Sonuç
ΔV ≈ 9,210 m/s
Sufficient for Earth orbit
Kaçınılması Gereken Yaygın Hatalar
- ✕Using natural logarithm (ln) instead of log₁₀
- ✕Confusing initial mass with fuel mass
Sık sorulan sorular
Why does mass ratio matter so much?
The logarithmic relationship means doubling the mass ratio roughly doubles the velocity change, making efficiency critical.
What determines exhaust velocity?
Exhaust velocity depends on propellant energy density and engine efficiency; chemical rockets are typically 3000-4500 m/s.
