mubody.core.kepler.reqins(Isp, DV, mf)#

Tsiolkovsky rocket equation inverse applied to a sequence of delta-v.

Computes the propellant mass required to obtain each delta-v in a rocket with a fixed dry mass.

Parameters:

  • Isp (float) – Engine specific impulse [s]

  • DV (float, list) – Delta-v performed [km/s]

  • mf (float) – Final mass after burn (m0) [kg]

Returns:

mi – Initial mass (m0 + mp) [kg]

Return type:

float, list
