An Analysis Method of Terminal Entry Angle Capability Based on Rapid High-Speed Maneuvering Trajectory Planning

For highly maneuverable high-speed vehicles, an analysis method of terminal entry angle capability based on rapid high-speed maneuvering trajectory planning is proposed in this paper. Firstly, in order to describe the coupling relationship between the transverse and longitudinal trajectory of high-speed vehicle and analyze its lateral maneuverability, the concept of maneuvering coefficient was proposed. Based on the maneuvering coefficient and the large circle distance, the remaining range is obtained and the longitudinal trajectory planning is be completed. Subsequently, to achieve the desired maneuvering coefficient and complete three-dimensional trajectory planning, a bank angle reversal logic based on an adjustable directional deviation corridor is adopted. Finally, using the vehicle and its performance parameters from chapter 3 of reference [1], different remaining range scenarios are simulated to obtain the range of maneuvering coefficients and heading angles corresponding to flight trajectory under multiple constraints.
