    摘要:

    活动翼面偏转过程中所承受的动态气动载荷大小随运动状态不断变化,方向始终垂直于翼面弦平面,因此,为了真实模拟活动翼面运动过程中真实受载状态,活动翼面功能试验加载过程需与翼面收放过程/状态连续和同步,具有随动跟踪翼面运动的能力,且确保载荷动态垂直于翼面。为满足试验加载要求,提出了一种摆臂式随动加载技术,并设计了随动加载装置,然后通过模拟试验验证了新方法的可行性,有效性和实用性,最后将该技术应用到某型号襟缝翼耐久性试验中,顺利完成了试验,经过数据分析,表明了该加载方法满足试验要求。

    Abstract:

    The dynamic aerodynamic load received during the deflection of the movable airfoil continuously changes with the state of motion, and the direction is always perpendicular to the chord plane of the airfoil. Therefore, in order to truly simulate the real load state during the motion of the movable airfoil, the movable airfoil function test load The process needs to be continuous and synchronized with the wing surface retracting process/state, with the ability to follow the wing surface movement, and to ensure that the load is dynamic perpendicular to the wing surface. In order to meet the test loading requirements, a swing arm type follow-up loading technology was proposed, and a follow-up loading device was designed. Then the feasibility, effectiveness and practicability of the new method were verified through simulation tests. Finally, the technology was applied to In the durability test of a certain model of flaps and slats, the test was successfully completed, and the data analysis showed that the loading method met the test requirements.
