| 1 | System of systems oriented flight vehicle conceptual design: Perspectives and progresses显示文摘In order to obtain optimized flight vehicle concepts which meet system of systems(So S)operation requirements,designers have to pay high attention to the impact of So S at conceptual design stage since operation environment goes increasingly complex.Based on this tendency,perspectives and progresses of So S oriented flight vehicle conceptual design,which is abbreviate as So Sed design,are reviewed in this paper.Such basic concepts of So S as definition,characteristics,differences between systems engineering and So S engineering,as well as So Sed design process are introduced,then So S engineering process model for research and development of flight vehicles and So Sed design wheel model for conceptual design are proposed.Related literature is classified and analyzed in accordance with four major elements including requirements,design concept,design analysis,and trade studies and optimization:typical So S architectures,description and quantization of indexes are introduced;Application of inverse design in designing concept is analyzed;Modeling and simulation(M&S)-based methods and their applications in So Sed effectiveness evaluation are highlighted;According to So Sed trade studies and optimization related research,the importance of such points as decision-making and using multidisciplinary design optimization for reference are emphasized.Finally,the value of So Sed design is concluded,and five directions which are worthy of attention in this field are presented. | Liu Hu Tian Yongliang Gao Yuan Bai Jinpeng Zheng Jiangan | 2015 | Chinese Journal of Aeronautics2015，28，3： | 18 |
| 2 | A fnite element parametric modeling technique of aircraft wing structures显示文摘A fnite element parametric modeling method of aircraft wing structures is proposed in this paper because of time-consuming characteristics of fnite element analysis pre-processing.The main research is positioned during the preliminary design phase of aircraft structures.A knowledgedriven system of fast fnite element modeling is built.Based on this method,employing a template parametric technique,knowledge including design methods,rules,and expert experience in the process of modeling is encapsulated and a fnite element model is established automatically,which greatly improves the speed,accuracy,and standardization degree of modeling.Skeleton model,geometric mesh model,and fnite element model including fnite element mesh and property data are established on parametric description and automatic update.The outcomes of research show that the method settles a series of problems of parameter association and model update in the process of fnite element modeling which establishes a key technical basis for fnite element parametric analysis and optimization design. | Tang Jiapeng Xi Ping Zhang Baoyuan Hu Bifu | 2013 | Chinese Journal of Aeronautics2013，26，5： | 9 |
| 3 | 面向航线网络体系的客机设计指标权衡方法显示文摘为了通过客机的市场分析与总体设计的紧密结合进行关键设计指标的更充分的权衡,提出了从航线网络体系的视角进行指标集效能评价的方法。这一方法以燃油效率作为经济性评价准则,基于运营统计数据建立综合考虑航线航程概率及航线实际乘客数概率的运输周转量概率密度分布,结合客机运行空重的估算,计算出各条航线消耗的燃油重量,进而通过多轮次的仿真分析出不同指标集对应的燃油效率概率密度。分析结果有助于权衡各个指标集的潜在设计方案适合在何种航线上运营,以及从燃油效率的角度分析潜在设计方案对航空公司的吸引力。通过在一个算例中对航程和载客量的变化进行计算和分析,说明了所提方法的应用方式,最后对目前研究的局限之处和后续的研究方向进行了探讨。 | 刘虎 田永亮 刘宇轩 孙奕捷 吴光辉 | 2016 | 航空学报2016，37，1： | 5 |
| 4 | Entropy based inverse design of aircraft mission success space in system-of-systems confrontation显示文摘This paper presents a practical and efficient design method for aircraft Mission Success Space(MSS)based on the entropy measurement(EM).First,fundamentals regarding MSS,Inverse Design(ID)and entropy are discussed.Then,two EM schemes of entropy-based ID and the whole MSS ID procedure are given to demonstrate alternative ways of entropy quantification and MSS design.After that,Genetic Algorithm(GA)is utilized as a search algorithm to find the optimal MSS design with the minimum objective,entropy,in each EM scheme.A simulation case of aircraft penetration mission is given for the method validation where the best aircraft MSS design is obtained by GA according to the minimum entropy.Results from two schemes are compared at the end. | Yuan GAO Yongliang TIAN Hu LIU Jianwen HU | 2021 | Chinese Journal of Aeronautics2021，34，12： | 2 |
| 5 | 面向体系化设计与运用的虚拟开放场景构建显示文摘场景作为飞行器设计方与使用方之间的重要桥梁,其复杂度随着飞行器的体系化发展趋势不断提高,使得双方需要更直观、更易理解、更高效的场景描述和构建方式,为设计与运用的相关应用提供“共同语境”。在典型的场景应用需求分析的基础上,提出了虚拟开放场景(VOS)的定义和主要特征,进而提出了场景要素的多维映射体(MDM)等概念及VOS构建流程。针对流程中的主要环节,提出了对MDM进行裁剪的双层评估矩阵、从MDM实例到组件的开放式封装等方法,并且探讨了一种支持VOS组合及交互的支持系统架构,以灵活构建可体现不同关注侧重的虚拟开放场景族。最后给出了一个面向多机海上搜救体系的虚拟开放场景族构建案例,实现了从全局视角和局部视角描述搜救直升机所在场景,验证了所提概念与方法的有效性。 | 刘虎 刘思良 田永亮 黄欣 赵沁平 | 2022 | 航空学报2022，43，10： | 0 |
