Abstract:

The point return of a vehicle with a lift-to-drag ratio of 12, returning from a lunar mission, was investigated. The range of a vehicle that is restricted to an altitude below 400,000 feet after entry is compared to the range of a vehicle that is allowed to skip to an altitude of 400 miles. Required entry conditions for point return are examined for sample cases of skip and no-skip trajectories.
