英文摘要: Motivated by the demand of designing Hypersonic Near Space Vehicles (HYNSV) on the national strategic level and aiming at designing the structure of HYNSVs, the present project focus on investigating the establishment of the overall architecture of Multidisciplinary Design and Optimization (MDO), optimization methods considering the thermal-mechanical coupling and multiple objective/constraint functions based on ultra-refined structural modeling, and the computable MDO formulations as well as its efficient solution approaches. Based on the achieved research results, a general MDO theoretical framework including the design, analysis and optimization of HYNSVs can be set up. It is believed that the present project can provide the fundamental theories and technical supports for the development of novel HYNSVs.
