- mubody.core.kepler.rocket_eq_mi(Isp, DV, mf)#
Tsiolkovsky rocket equation inverse to obtain initial mass.
Computes the propellant mass required to obtain a given delta-v in a rocket with a fixed dry mass.
- Parameters:
Isp (float) – Engine specific impulse [s]
DV (float) – Delta-v performed [km/s]
mf (float) – Final mass after burn (m0) [kg]
- Returns:
mi – Initial mass (m0 + mp) [kg]
- Return type:
float
