The invention discloses a multi-stage telescopic wing follow-up loading device capable of simulating uniformly distributed aerodynamic loads, relates to the technical field of aviation experiment testing, and solves the problems of high cost, long preparation period and danger of a traditional aircraft variable swept wing performance test. The device comprises a bearing table, a test airfoil and a plurality of force load applying devices, the bearing table comprises an upper bearing table and a lower bearing table, the test airfoil is arranged on the upper bearing table, and the force load applying devices are arranged on the lower bearing table; the force load applying device is in contact with the lower surface of the test airfoil; the force load applying device comprises a servo electric cylinder, the servo electric cylinder is connected with the lower bearing table, and the upper half part of the force load applying device is pushed by the servo electric cylinder to move upwards to apply a load to the test airfoil. According to the deformed wing follow-up loading device, the force load applying time and the load size are flexibly controlled through the force load applying device, so that the load acting on the tested wing surface approximately simulates the effect of an aerodynamic load, and the deformed wing follow-up loading device can be deformed along with the wing surface.

    本发明公开了一种可模拟均布气动载荷的多级伸缩翼随动加载装置,涉及航空实验测试技术领域,解决了传统飞行器变后掠翼性能试验成本高、准备周期长且存在危险的问题。本发明包括承载台、测试翼面和若干力载荷施加装置,承载台包括上承载台和下承载台,测试翼面设置在上承载台上,力载荷施加装置设置在下承载台;力载荷施加装置和测试翼面下表面接触;力载荷施加装置包括伺服电缸,伺服电缸和下承载台连接,通过伺服电缸推动力载荷施加装置上半部分向上移动对测试翼面施加载荷。本发明通过力载荷施加装置灵活控制力载荷施加时间及载荷大小,使作用在测试翼面上的载荷近似模拟气动载荷作用时的效果且能够实现跟随翼面变形的一种变形翼随动加载装置。
