摘要
针对一体化飞行器在控制特性研究中面临的数据不足与多因素耦合问题,借鉴X-51A、PRORA-USV1的研制过程,提出一种增量方法,以较小代价获得足够的气动数据集,并建立面向控制的气动力模型。通过静稳定性分析,获得了与X-51A官方报告一致的结论(即,飞行器静不稳定),表明建立的气动力模型具备了该类飞行器气动特性。提出一种改进伪谱法计算出优化的最大航程滑翔弹道,仿真结果表明所建立的气动力模型完备、弹道规划方法有效。
Aiming at the problem of insufficient data and multi-factor coupling in the control characteristics research of the integrated Vehicle,a build-up approach was proposed on the basis of the development experiences of X-51A and PRORA-USV1,to obtain sufficient aerodynamic data sets at a small cost and establish a control-oriented aerodynamic model.The result of static stability analysis for the model consistent with the result of X-51A in official report(that is,the vehicle is static instability),which proves that the aerodynamic model established has the aerodynamic characteristics of a class of vehicle such as X-51A.An improved pseudo-spectral method is proposed to calculate the optimal maximum range glide trajectory.The simulation results show that the aerodynamic build-up model is complete and the method of trajectory planning is effective.
