Abstract | A trajectory planning approach is proposed for the reentry vehicle with relatively high lift-to-drag ratio. Multiple constraints including waypoints and no-fly zones are taken into consideration. The three-dimensional trajectory planning problem is decomposed into a longitudinal trajectory planning subproblem and a lateral trajectory planning subproblem. The former is to determine a drag-energy profile (D-E profile) that is consistent with the required trajectory length and satisfies the given path constraints except waypoints and no-fly zones. The latter is to specify the sign of bank angle for satisfying the waypoint and no-fly zone constraints and minimizing the final crossrange error. The trajectory length and lateral maneuverability may not meet requirements, so an adjustment of D-E profile is required after solving the previous subproblems. Thus, the longitudinal trajectory planning and lateral trajectory planning subproblems are iteratively solved to converge to a feasible three-dimensional trajectory which meets all the path and terminal constraints. The trajectory planning approach is tested using the Common Aero Vehicle model. Simulations demonstrate that the approach consistently achieves the desired target conditions within allowable tolerances and satisfies waypoint and no-fly zone constraints. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
