Abstract
Discrete-event drag-modulation trajectory control is assessed for planetary entry using the analytical Allen-Eggers approximate solution to the equations of motion. A control authority metric for drag-modulation trajectory control systems is derived. Closed-form relationships are developed to assess range divert capability, identify jettison condition constraints for limiting peak acceleration and peak heat rate. Discrete-event drag-modulation systems with single stages and an arbitrary number of stages are assessed.
