    摘要:

    为满足现代大型飞机先进增升装置多目标综合最优的设计目标,本文结合气动、机构并行设计思想,基于VB、Qt和Catia二次开发环境搭建了增升装置气动、机构综合设计软件。其中包括翼身组合体、巡航构型、起降构型和机构设计四个设计模块,用户可从不同翼身截面数据点,通过拉伸组合成用户所设计的干净构型;利用NURBS曲线使干净构型快速切割出带增升装置的曲面外形;根据缝道参数经验值和机构约束将所切增升装置偏转并设计出合适的起飞、着陆卡位模型,并配以对应卡位设计机构。本文通过对多架、多类别大型客机进行设计并按照预期设计完成切割,完成不同固定翼机型以及翼身组合体机型的切割。经过大量的设计实例验证,软件具有广泛的通用性,能够实现对任意飞机的增升装置进行快速设计。

    Abstract:

    In order to meet the multi-objective comprehensive optimal design goal of advanced high lift device for modern large aircraft, this paper combines the concurrent design idea of aerodynamics and mechanism, and builds the comprehensive design software of aerodynamics and mechanism of high lift device based on VB, QT and CATIA secondary development environment. It includes four design modules: wing body assembly, cruise configuration, take-off and landing configuration, mechanism design. Users can draw and combine the data points of different wing body sections to form the clean configuration designed by users. The NURBS curve is used to make the clean configuration quickly cut the curved surface shape with high lift device. According to the empirical values of gap parameters and mechanism constraints, the cutting high lift device is deflected and the appropriate take-off and landing positioning models are designed, and the corresponding positioning design mechanism is matched. This paper designs multi category large commercial aircraft, and according to the expected design, complete the cutting of different fixed wing models and wing body combination models. Verified by a large number of design examples, the software has a wide range of versatility, and can realize the rapid design of any aircraft lift device.
