中航飞机研发中心:抢占前沿 追求卓越 :enjoy:

“协同设计”引发飞机

总体设计的变革

中航飞机研发中心是我国目前唯一集歼击轰炸机、轰炸机、民用飞机、运输机和特种飞机设计研究于一体的国家级大中型军民用飞机设计研发基地,而总体气动设计研究则是中航飞机研发中心的“龙头”单位,是型号研制的原点、设计技术的聚点。

中航飞机研发中心总体气动设计研究所主要承担着军用、民用、通用、特种飞机的气动布局设计、人机工效综合设计、重量与平衡设计、隐身技术设计、短舱及进排气系统设计、气动计算分析、风洞试验技术、静气弹分析、载荷设计计算、操稳和性能设计分析、总体布置与外形设计、技术状态管理等工作。在几十年的型号研制历程中,他们先后完成了歼轰7系列、空警2000、运7系列、运8系列、轰6系列、“小鹰”500等重大型号的总体方案设计,以及若干重大预研课题的总体、气动研究,基本掌握了覆盖大中型飞机总体气动方案设计、计算、试验、分析全过程的关键技术,目前总体气动所包含14个主干专业、74个子专业,形成了先进、完整的设计体系。

多年来,总体气动人不懈努力、孜孜以求,先后攻克了大型飞机总体布局设计大型飞机超临界机翼设计全三维数字化设计及电子协调样机多乘员多任务系统驾驶舱综合设计背负式锯等齿型并列双发大S弯进气道一系列国内领先的关键技术,不断提升总体气动设计能力。同时,他们还与俄罗斯TsAGI,欧洲ETW、DNW、CIRA等国外研究机构开展了广泛的技术合作与交流,不断开拓技术视野,促进总体气动设计技术与国际接轨,使研发中心的总体气动设计能力始终居于行业前列。

国家重大专项研制中,他们以型号研制为契机,通过型号研制提升综合技术手段与水平。在认真思考、总结以往设计经验的基础上,他们本着提高设计协作、减少中间消耗、增加推进力度、规范工作过程的原则,积极探索更加先进、更适合现代飞机设计的手段和方法。经过近5年的艰辛求索,研发出具有独创技术理念的“飞机总体协同设计系统”

在“飞机总体协同设计系统”的研发过程中,总体气动所组织资深专家与技术人员,从设计流程、手段、人效、数据四要素出发,充分借鉴波音、空客、NASA Ames等研究设计机构的特点与做法,摒弃国内现有的生产线式研发平台的技术弊端,采用以数据中心为核心的柔性流程设计,将规范化和人效作用有机结合,使专业间从以往的串联设计走向了多学科协同设计,满足了现代飞机设计的技术特征,达到了国外最先进的第三代平台的技术水平。

要实现目标协同、过程协同和结果协同,而“飞机总体协同设计系统”就是实现这些协同的必要手段和平台。

经过型号的应用与测试,在国家重大专项研制过程中采用该系统后,设计效率提高了35%以上,设计协调性提高了20%上,数据的追溯性、有序性提高了25%以上。

这是当前飞机总体设计的一场变革。它实现了总体设计从“方案牵引型”向“协同设计型”的转变,有力提升了我国飞机总体设计的协调性和规范性,使飞机总体方案设计从技术跟踪时代进入全面研发时代,也使我国当前的飞机设计水平迈上了新的高度。

Interesting, however link You added ends somewhere after "..." and is broken.
Could You please repost that link ?

Even more could You probably please highlight the relevat / important part of this text ? ... for those who can't read Chinese.

Thanks in advance,

AVIC Aircraft R & D center: to seize the forefront of the pursuit of excellence: enjoy:

"Collaborative design" caused the plane

The overall design changes

AVIC Aircraft R & D center in China is currently the only set of fighter-bombers, bombers, civilian aircraft, transport planes and special aircraft design studies in one of the national medium-sized military and civilian aircraft design and development base, while the overall aerodynamic design study is a research and development center of AVIC Aircraft. " leading "units, is the origin of model development, design focal point.

Overall aerodynamic design Institute of AVIC Aircraft R & D center is mainly responsible for the military, civilian, general, special aircraft's aerodynamic configuration design, integrated design ergonomics, weight and balance design, stealth technology design, nacelle design and intake and exhaust systems, pneumatic calculation and analysis, wind tunnel test technology, static aeroelastic analysis, design load calculations, handling stability and performance design analysis, overall layout and exterior design, configuration management. After decades of model development process, they have completed the JH-7 series, air marshals 2000, Y-7 series, Y-8 series, H-6 series, the overall design, "Kitty Hawk" 500 and other major models, as well as several Overall, pneumatic research topics important preliminary research, basic grasp of the overall coverage of medium-sized aircraft aerodynamic design, calculations, tests, analyzes the key technology of the whole process, the current overall aerodynamic trunk contained 14 professional and 74 sub-professional, formation of an advanced , complete design system.

Over the years, the overall aerodynamic unremitting efforts, assiduous, has tackled the overall layout of large aircraft, large aircraft supercritical wing design, the full three-dimensional digital design and prototype electronic coordination, multi-crew cockpit multitasking system integrated design, carrying saws and other tooth parallel twin large S shaped inlet leading a series of key technologies, and improve the overall aerodynamic design capabilities. At the same time, they also with Russia TsAGI, Europe ETW, DNW, CIRA and other foreign research institutions to carry out a wide range of technical cooperation and exchanges, and constantly open technology vision, promote the overall aerodynamic design technology and international standards, so that the overall aerodynamic design capability R & D center is always living in the forefront of the industry.

In developed countries, major projects, they model development as an opportunity to improve the overall level of technology and models developed by. In serious consideration, sum up past experience in the design, based on their spirit of collaboration to improve design, reduce intermediate consumption, increase efforts to promote and standardize the work process, and actively explore more advanced, more suitable means and methods of modern aircraft design. After nearly five years of arduous explorations, original technology developed with the concept of "total aircraft collaborative design system."

In the "Aircraft collaborative design system," the R & D process, the overall aerodynamic organized by senior experts and technical personnel, from the design process, tools, people efficiency, data four elements, to fully draw on Boeing, Airbus, NASA Ames research design agency characteristics and practices, abandon existing technical shortcomings of the domestic production line in R & D platform, the use of a data center as the core of a flexible process design, the role of standardization and efficiency of the combination of people, so that inter-professional strike from the previous series of multi-disciplinary design collaborative design, to meet the technical characteristics of modern aircraft design, reached the technical level of the most advanced third-generation platform.

To achieve the target synergies, collaborative process and the results of synergy, and "Aircraft collaborative design system" is a necessary means to achieve these synergies and internet.

After the model application and testing, using the system at the national major projects the development process, the design efficiency is improved by 35% or more, designed to improve coordination on the 20%, retroactively, ordering data increased by more than 25%.

This is currently a revolution in aircraft design. It implements the overall design from the "Programme traction" to "co-design" of the changes, effectively enhance the coordination of aircraft design and normative, the overall design of the aircraft entered the era of comprehensive development of the technology to track the times, but also to China's current level of aircraft design to a new height.
