【摘要】 针对某高速、低空恒高拖靶系统研制的需求,设计了一种有良好气动特性、结构简单、工艺性好、成本低的拖靶总体方案。为了进一步减少气动阻力,采用基于Kriging模型的优化方法对高速拖靶气动外形进行了优化设计。优化结果表明:在满足操纵力和稳定性要求前提下,优化后拖靶的气动阻力明显减小。本文研究结果为整个拖靶系统的进一步设计和论证奠定了基础。更多还原

【Abstract】 To meet the requirements of a high-speed,low-altitude tow target system,a conceptual design for the tow target is completed,including good aerodynamic efficiency,structural simplicity,good manufacturability and low cost.The optimization method based on Kriging model is used to reduce the aerodynamic drag of the tow target.Results indicate that the drag is significantly reduced after the optimization.And all the requirements for the control ability and the stability are satisfied.The research provides a foundation for the further development of the tow target system.更多还原
