大型飞机增升装置气动机构一体化设计平台的创建

根据大型飞机整体技术要求和起飞着陆增升装置设计总要求,确定增升装置总体设计流程,建立气动机构一体化设计思想。在CATIA环境下进行二次开发,将气动、机构连接起来,形成一体化设计与仿真平台。平台的功能可以实现通过用户输入缝道参数和选择增升装置机构来驱动CATIA生成相应的增升装置的执行机构和传动机构,最后通过调用CFD工具来评估大型飞机的起飞着陆性能是否满足总体设计要求。

Aero-mechanism Integrated Design Platform for High Lift Devices on Large Aircraft

According to the whole technological demands and takeoff and landing demands for high lift devices on large aircrafts, this article summarizes a process of how to design high lift devices and presents an integrated design idea connecting aerodynamics and mechanism design. By use of the secondary development of CATIA, a set of aero-mechanism integrated design platform is established, which provides users takeoff/landing configurations of high lift devices with the inputs of design parameters as well as supporting systems. Finally using efficient aerodynamic evaluation measures judges whether the takeoff/landing performance of high lift devices under the guidance of the mechanisms meet the requirements of the overall design.
