LUNAR LANDING AND TAKE-OFF

Abstract

An assumption of the uniform gravity field of the Moon was justified, by computing errors due to this assumption and by establishing the limits within which the simplified computations should be performed. Vertical take-off and ascent from the Lunar surface was analyzed for different values of a constant propellant flow. The analysis of the vertical descent and landing was extended to the cases of a constant propellant flow and thrust, to the modulated and intermittent thrust. AL NUMERICAL EXAMPLES WERE COMPUTED WITHOUT EMBARKING ON A GENERALIZED OPTIMIZATION PROBLEM, BUT BY INDICATING THE WAYS OF MINIMIZING THE PROPELLANT CONSUMPTION.
