摘    要:建立了基于试验设计理论和响应面近似的超燃冲压发动机推进的高超声速巡航飞行器多学科设计优化方法。首先建立外形尺寸、质量估算、气动力性能、气动热性能和推进性能学科的分析模型。模型考虑了学科间的耦合效应,结合弹道方程,形成了飞行器的总体性能模型。然后分别采用D—Optimal设计、Taguchi设计和均匀设计选择设计点,通过多机并行计算完成高超声速巡航飞行器性能分析。根据分析结果,构造响应面近似模型。通过响应面近似模型的优化,完成了高超声速巡航飞行器的多学科设计优化。计算表明,基于试验设计的多学科设计优化方法可以用于高超声速巡航飞行器的优化设计。

关 键 词:高超声速巡航飞行器  多学科设计优化  响应面近似  试验设计  并行计算

Abstract:An effort to multidisciplinary design optimization (MDO) of a hypersonic cruise vehicle propelled by scramjet engine based on design of experiment (DOE) and response surface approximation methods is presented. By developing disciplinary analysis models including mass properties estimation, aerodynamic forces, aeroheating, scramjet, control and trajectory performance models, taking into account the interactions between different disciplinary, a hypersonic cruise vehicle overall performance analysis model is set up. After employing D-Optimal design, Taguchi design and uniform design methods to select design points respectively, the vehicle performance is analyzed via parallel computation, corresponding response surface approximation models are constructed based on performance analysis results. The response surface approximation models are used to replace the original complex vehicle performance model, the optimization is conducted using a sequential quadratic programming algorithm. Numerical results show that MDO methods based on design of experiments theory is promising in conceptual design for hypersonic cruise vehicle.
Keywords:Hypersonic cruise vehicle  Multidisciplinary design optimization  Response surface  Design of experiment  Parallel computation
