Abstract
The paper describes the development of attitude control system of a low L/D atmospheric entry capsule with multiple equilibrium points. The critical phase of flight occurs during the atmospheric aborts where the capsule gets separated from the abort vehicle at an unfavorable angle of attack and traverses multiple equilibrium points to reach the desired trim angle of attack. The nonlinear nature of aerodynamics and control law makes the problem challenging. The objective of this paper is to describe the challenges encountered and solution proposed in the development of control law for the crew capsule during re-entry. Phase plane analysis is extensively used as a tool to develop the control strategy. Performance of the proposed RCS control law is established using 6- DoF simulations for different flight conditions.
