摘要
前缘缝翼系统设计是一个涉及多目标、多学科综合的问题。针对这一复杂问题,首先解决了前缘缝翼支撑与驱动机构设计的诸多难点,然后利用CATIA二次开发技术,建立了一套气动和机构一体化设计平台,将前缘缝翼气动设计和机构设计有机地结合起来。大型客机前缘缝翼气动机构一体化设计子平台的功能是向用户提供前缘缝翼以及支撑与驱动机构设计参数的输入;然后驱动CATIA自动生成前缘缝翼起飞着陆状态的气动外形;在此基础上自动生成支撑与驱动机构零件,装配并仿真;最后通过高效的气动评估方法来评估前缘缝翼在机构引导下得到的起飞着陆性能是否满足总体设计要求。
The design of slat system is a multi-target and muhidisciplinary problem. In response to this complex issue, firstly difficult points in the design of the support and driving mechanism of leading edge slats are solved. Then by using the secondary development of CATIA, a set of aero-mechanism integrated design platform is estab- lished, which organically combines the leading edge slats aerodynamic design with the mechanism design. The function of this platform is to provide users with the inputs of the leading edge slats design parameters as well as support and drive mechanism design parameters, hereafter drive CATIA automatically generate leading slats and their takeoff/landing configurations, on this basis automatically generate the support and drive mechanism parts, and then finish the assembly and simulation, Finally by using efficient aerodynamic evaluation measures to judge whether the takeoff/landing performance of leading edge slats under the guidance of the mechanism meet the re- quirements of the overall design.
