摘要
高效的增升装置是现代大型飞机研制中的关键技术之一。详细介绍了增升装置的原理和现代大型飞机常用的增升装置类型及其支撑与驱动机构。增升装置设计是一个多学科多目标的问题,从气动性能要求、噪声要求和结构重量要求几个方面介绍了增升装置的设计目标。研究了增升装置的发展历程和气动计算与实验方法,最后提出了增升装置的发展趋势和新技术。
Efifcient high-lift device is one of the most important technologies in modern large aircraft research. High-lift theory was introduced in detail, including several types of common high-lift devices as well as their supporting and driving mechanisms. Since high-lift system design involves multidisciplinary and multi-objective issues, this paper introduced several design objectives of high-lift system in terms of aerodynamic performance, noise requirement and structural weight. Also, the development history of high-lift devices was studied, as well as the CFD technology and experiment approach. At last, this paper presented the development tendency of high-lift device and some promising technologies.
