Trajectory generation with complex no-fly zone constraints for hypersonic morphing vehicle

Abstract

This paper investigates the flight capability and trajectory generation of hypersonic morphing vehicles under complex no-fly zone constraints. A target flight path containing only position information is constructed and discretized based on the characteristics of the complex no-fly zone. An optimization model for the control variables is formulated, and an iterative stepping strategy along with a no- ly zone avoidance strategy is designed to develop a tracking algorithm for the target flight path. The trajectory generation algorithm for complex no-fly zone constraints is then completed. The reachable domain under no-fly zone constraints and the applicability of the proposed algorithms are analyzed using both a hypersonic morphing vehicle model and a hypersonic fixed-wing vehicle model. Simulation results demonstrate that the hypersonic morphing vehicle can utilize the proposed trajectory generation algorithm to design a feasible trajectory that complies with the complex no-fly zone constraints. Compared with the hypersonic fixed-wing vehicle, the hypersonic morphing vehicle exhibits a larger reachable domain under no-fly zone constraints and demonstrates a stronger capability for avoiding complex no-fly zone constraints.
