摘　　要：依托一款针对混合翼身布局(Hybrid Wing Body,HWB)民机的多学科优化设计平台,开展4组优化计算,对每组优化计算设定不同的纵向静稳定裕度约束范围。由于静稳定裕度对HWB飞机机身布局的决定性影响,在不同的静稳定裕度约束的作用下,4组优化计算的结果(以pareto前沿解集的形式存在)对应的HWB构型,呈现出不同的后机身长度。基于这4组pareto前沿解集对应的HWB飞机构型族,进行基础动力学性能估算与比较,研究后机身延长设计对HWB民机动力学性能的影响规律。Based on a physics-based multidisciplinary optimization design platform of Hybrid Wing Body(HWB)civil aircraft,four groups of optimization calculations were carried out.Different constraint ranges of longitudinal static stability margin are set for each group of optimization calculation.Due to the decisive influence of static stability margin on HWB fuselage layout,under the influence of different static stability margin constraints,the HWB configurations corresponding to the four groups of optimization results(existing in the form of Pareto frontier solution sets)show different aft-fuselage lengths.Based on the HWB configuration family corresponding to the four Pareto front solution sets,the fundamental dynamics performance of HWB civil aircraft was estimated and compared,and the influence of aft-fuselage extending design on the dynamics performance of HWB civil aircraft was studied.
