box rib
former
wing rib

Examples

  1. Computation of the transient temperature distribution of the spar - rib of the rlv during the reentry
    可重复使用飞行器翼肋的再入瞬态温度分布计算
  2. Integrally cast body ribs , running parallel and perpendicular to the pipe axis , impart additional strength for high pressure conditions , thermal and pipe loads
    整体铸造阀体翼肋,与管路轴线平行和垂直,增加了阀体强度,适用于高压环境、高温和管道负载。
  3. Stiff struts and ribs meant that wings were too rigid to flex much torsionally , so builders installed ailerons ? flaps located on the outer , trailing - edge portions of wings
    难以弯曲的支柱和翼肋,使得机翼太过刚硬,同时也限制了扭转幅度,因此工程师加上了副翼,也就是位于机翼后缘外侧的襟翼。
  4. Boeing ' s activities grew out of president nixon ' s visit in 1972 and the company now buys parts from chinese suppliers for all of its aircraft , including doors and wing panels for the 737 , wing - ribs for the 747 and the rudder [ 2 ] for the new 787
    1972年尼克松访华为波音叩响了中国的大门,现在该公司所有飞机的零部件,如737的舱门和翼片、 747的翼肋及787新机型的方向舵,都购自中国供应商。
  5. Abstract : a new method , collaborative allocation ( ca ) , is proposed to solve the large - scale optimum allocation problem in aircraft conceptual design . according to the characteristics of optimum allocation in aircraft conceptual design . the principle and mathematical model of ca are established . the optimum allocation problem is decomposed into one main optimization problem and several sub - optimization problems . a group of design requirements for subsystems are provided by the main system respectively , and the subsystems execute their own optimizations or further provide the detailed design requirements to the bottom components of aircraft , such as spars , ribs and skins , etc . the subsystems minimize the discrepancy between their own local variables and the corresponding allocated values , and then return the optimization results to main optimization . the main optimization is performed to reallocate the design requirements for improving the integration performance and progressing toward the compatibilities among subsystems . ca provides the general optimum allocation architecture and is easy to be carried out . furthermore , the concurrent computation can also be realized . two examples of optimum reliability allocation are used to describe the implementation procedure of ca for two - level allocation and three - level allocation respectively , and to validate preliminarily its correctness and effectiveness . it is shown that the developed method can be successfully used in optimum allocation of design requirements . then taking weight requirement allocation as example , the mathematical model and solution procedure for collaborative allocation of design requirements in aircraft conceptual design are briefly depicted
    文摘:探讨了一种新的设计指标最优分配方法- -协同分配法,用于处理飞机顶层设计中的大规模设计指标最优分配问题.分析了飞机顶层设计中的设计指标最优分配特征,据此给出了协同法的原理并建立了数学模型.协同法按设计指标分配关系将最优分配问题分解为主系统优化和子系统优化,主优化对子系统设计指标进行最优分配,子优化以最小化分配设计指标值与期望设计指标值之间的差异为目标,进行子系统最优设计,或对底层元件(如飞机翼梁、翼肋和翼盒等)进行设计指标最优分配,并把最优解信息反馈给主优化.主优化通过子优化最优解信息构成的一致性约束协调分配量,提高系统整体性能,并重新给出分配方案.主系统与子系统反复协调,直到得到设计指标最优分配方案.两层可靠度指标分配算例初步验证了本文方法的正确性与可行性,三层可靠度指标分配算例证明了本文方法的有效性.最后,以重量指标分配为例,简要叙述了针对飞机顶层设计中设计指标协同分配的数学模型和求解思路
