摘要
Abstract
Compared to traditional over-shoulder-launched aircrafts,aircrafts based on the post-stall re-orientation technique have operational advantages,such as short response time,high manoeuvrability,and long range.Therefore,it is an advantageous option for the new generation of air-launched aircrafts to achieve omnidirectional attack.Focusing on the manoeuvre course of the post-stall re-orientation slender body,CFD simulations were performed to analyze the aerodynamic characteristics in this study.By improving the differential equation method,the hysteresis characteristics that exist in the post-stall re-orientation process can be successfully predicted.At the same time,the applicability of the least square support vector machine(LS-SVM)method in modeling such a problem has been verified.The present method can capture the non-linear unsteady aerodynamic characteristics in the re-orientation process,which provides a foundation in the control law design for post-stall re-orientation slender body.关键词
