Maximum Atmospheric Entry Angle for Specified Retrofire Impulse

T. N. Srivastava, O. P. Nagpal

Abstract


Maximum atmospheric entry angles for vehicles initially moving in elliptic orbits are investigated and it is shown that tangential retrofire impulse at the apogee results in the maximum entry angle. Equivalence of maximizing the entry angle and minimizing the retrofire impulse is also established.

Keywords
