大型客机后缘铰链襟翼气动机构一体化设计研究

我国正在开展大型客机的研制工作,增升装置设计是其中的关键技术之一。借鉴A350和波音787的后缘增升装置及其机构特点,研究了后缘铰链襟翼气动和机构一体化的设计。后缘铰链襟翼,是利用简单铰链机构驱动的后缘单缝襟翼增升装置,该机构由于构造简单、维护方便、制造成本低等优点备受青睐。详细介绍了基于CATIA二次开发创建的后缘铰链襟翼气动机构一体化设计模块,并嵌入到原大型飞机增升装置气动机构一体化设计平台上,获得较好的效果,为我国未来大型客机增升装置设计奠定了技术储备。

Aero-mechanism Intergrated Design of Trailing Edge Hinge Flap Devices for Large Aircraft

High-Lift device design is one of the key technologies during the development of large aircraft in China. Refered to the trailing edge high lift and its characteristic of airplane A350 and B787, aero-mechanism intergrated design of trailing edge hinge flap is researched. Trailing edge hinge flap is one of new advance high lift devices which uses simple hinge device to drive trailing edge high lift system. The advantage and disadvantage of the hinge flap with good prospects for development has been discussed. Aero-mechanism intergrated design modules are introduced in detail, which intergrated design of trailing edge hinge flap has been established based on the secondary development of CATIA. And the aero-mechanism intergrated design modules are set in an intergrated design platform. The platform improves efficiency for designing high lift device of large aircraft. The good results show that the design points out the development direction of high lift device on large aircraft and provides advices for further study.
