A landing footprint calculation method is developed for reentry vehicles based on the altitude versus velocity profile with path constraints, the maximum footprint is calculated with optimized angle of attack (AOA) profiles. We first connect the range with altitude versus velocity profile, with the determined AOA profile and quasi-equilibrium glide condition (QEGC), the footprint is calculated by interpolated altitude profiles. Then we consider the impact of AOA, the maximum downrange AOA profile solving method is built with path constraints and maximum L/D AOA, and the maximum crossrange AOA profile is parameterized and optimized by SQP method though simplified crossrange dynamic equations. Finally, footprints with different AOA profiles are calculated and compared, and then the maximum footprint is generated by interpolated with the maximum downrange and the maximum crossrange AOA profiles obtained previously.
