| Abstract | A generic reentry guidance trajectory planning algorithm of a Reusable Launch Vehicle is presented in this paper. The study is aimed at the development of a trajectory planning algorithm, which is accurate, efficient, robust and reconfigurable. In order to achieve the above objectives, the proposed reentry trajectory planning algorithm generates the optimum reference trajectory from any reentry interface to a specific target location meeting all the path constraints real time. The applicable optimal control problem of reentry guidance is converted into an equivalent targeting problem in Nonlinear Programming and a simplified solution methodology is devised to solve the three dimensional trajectory planning without using bank reversals. The necessary mathematical models are represented in polar coordinate system and a judicious selection of control parameters, coupled with an efficient method of computation of sensitivity matrix elements, ensures better mission planning and faster convergence. The performance results establish the mission flexibility of steering the vehicle from widely separated reentry locations, while meeting the path constraints. The guidance law and the models are general and adaptable to any RLV mission and have the potential for onboard implementation. |
