- poliastro2.math.threebody.cr3bp_quantities_calculations.calculate_mu(mu1, mu2)¶
Calculate mu of CR3BP.
- Parameters:
mu1 (float, km^3*s^-2) – mu of P1
mu2 (float, km^3*s^-2) – mu of P2
- Returns:
mu – mu2/(mu1+mu2), mu2<mu1
- Return type:
float, dimensionless
- poliastro2.math.threebody.cr3bp_quantities_calculations.calculate_tstar(mu1, mu2, lstar)¶
Calculate t* of CR3BP.
- Parameters:
mu1 (float, km^3*s^-2) – mu of P1
mu2 (float, km^3*s^-2) – mu of P2
lstar (float, km) – Characterisitc length of P1 - P2 system
- Returns:
tstar (float, sec) – Characterisitc time of P1-P2 system Explicitly converted to u.s as mu1 and mu2 may be of different units
.. math:: – sqrt{frac{l*^3}{M1+M2}}
