摘　　要：后缘襟翼在飞机飞行过程中发挥着重要作用,作用于其表面的气动载荷的大小和方向伴随其收起和展开而不断变化,给襟翼结构/机构地面试验气动载荷模拟带来很大困难。随动加载技术是解决该问题的关键技术。本文将工程中现有的后缘襟翼随动加载技术归纳为合成式随动加载技术、转轴式随动加载技术和多自由度分离式随动加载技术,并通过原理和工程应用案例进行分析,为飞机襟翼结构/机构地面试验验证提供技术支持。Trailing edge flaps play an important role in the aircraft.The magnitude and direction of the air loads around flaps are changing while the trailing edge flaps are deploying and retracting,which brings difficulties to the air loads simulation during the ground test.Three kinds of loading technologies used widely are proposed in the paper.They are introduced from the principle and engineering cases and can provide reference for the ground test of flap structure/mechanism.
