| 2. | Benefit research of relaxing static stability on a civil airplane 民用飞机放宽静稳定性的效益分析研究 |
| 3. | For civil airplane , the good or the bad of its maintainability will directly affects its whole life costs and affects its competition in the market 对于民用飞机,其维修性的好坏将直接影响其全寿命周期费用,也将影响其市场竞争力。 |
| 4. | Validation method of civil airplane maintainability qualitative parameters is instructive to constitute successfully a computer system of maintainability evaluation and validation of airplane 最后以主起落架机轮组的装配图为例,详细说明了计算机辅助验证方法。 |
| 5. | This paper firstly put forward maintainability qualitative parameters being the same with civil airplane based on traversing maintainability qualitative parameters of warplane 本文在详细研究军用飞机维修性定性指标体系的基础上,提出了适用于民用飞机的维修性定性指标体系。 |
| 6. | Supercritical wings have been widely used on modern civil airplanes and military transports due to their higher aerodynamic efficiency , higher cruising mach number and greater relative thickness 超临界机翼由于其具有较高的气动效率、较高的巡航马赫数及较大的机翼相对厚度而被广泛应用于新一代民用飞机及军用运输机上。 |
| 7. | Developing civil airplane market has become an important stratagem for many airplane manufacturing companies . and developing civil airplane has been a good method to improve our level of airplane development and pursue after the world advanced technology 大力发展民用飞机市场已成为国内各大飞机公司的战略方向,而民用飞机的研制也成为我国提高飞机研制水平,追赶世界领先水平的有效途径。 |
| 8. | Simulation results demonstrate that iced aircraft envelope protection is capable of successfully avoiding incidents and accidents during flight in icing conditions , provide flying safety , operate definite action on the design of next generation civil airplane 研究结果表明,结冰飞行包线保护系统将极大增强飞机容冰能力,保证飞机在各种结冰情况下的飞行安全,在下一代民机的研制中起到一定的作用。 |
| 9. | In the process of maintainability virtual analysis , sample based on computer is used instead of full - scale sample , which has the disadvantage of long manufacture cycle , high cost , and difficult correcting . it will expose the design problem of maintainability of civil airplane to the early stage of design 维修性虚拟分析以基于计算机的样机代替实物样机,克服了实物样机制造周期长、成本高、难以修改的缺点,并能将维修性设计问题暴露在设计初期。 |
| 10. | This paper investigates the condition and actual problems of civil airplane development , and then brings forward the plan that the correct management concept must be set up first , and we improve on the management process with this idea : in view of the complication and the condition of civil airplane development , general organizing structure in project management , we redesign the organizing structure - the strong matrix based the tetrahedral coordinates . analyze the management job of the civil airplane development , then research management process with the idea of project management , set up the new whole work flow . research some work flow such as risk management as a hotspot in project management 本文针对民用飞机研制的现状及存在的问题,提出了必须建立现代项目管理理念,用项目管理的思想来改进民机研制的管理流程:针对民机的复杂性,结合项目管理常用组织结构和民机研制项目现有的情况,对民机研制的组织结构进行了重组,建立了基于“四坐标”管理的强矩阵组织结构;在对民用飞机研制的管理工作充分分析的基础上,按项目的生命周期,用项目管理的方法对民机研制的管理流程进行了研究,建立了新的、符合项目管理要求的民机研制项目总体流程;研究了民机研制项目具体工作流程。 |
