Parallel Generate Entry Landing Footprint Using Differential Evolution

Landing footprint of an entry vehicle provides critical information for mission planning. Conventional methods calculate it through solving a family of multi-constraints optimal control problems. It is difficult to solve. To generate the boundary of it, we proposed a new scheme based on differential evolution(DE). Utilizing DE´s parallelism, each run generates one side instead of one point of the boundary. To get the full boundary, just need run the algorithm two times. The algorithm´s merits include accurate, fast, not relying on simplification of the system, all control variables are under consideration and facilitating parallel programming.
