在飞机机身的上下位置分别安装一个激光器,提出了一种实时测量在飞行过程中机翼弹性变形量的方法。以激光器与安装反射镜的机翼顶端之间的测量距离数据为依据,得到机翼或机身上任意点的实时变形量。机翼或机身上任意点的实时变形量是从机翼变形数据库中提取的数据量计算得到。根据弹性薄板理论,利用理想二维梁为例说明了该方法的实现过程,并且进行仿真说明。该方法对实时测量机翼弹性变形量具有普遍意义和实际应用价值。
In the upper and lower positions of the aircraft fuselage were installed a laser, put forward a real-time measurement of the wing during the flight elastic deformation. Based on the measured distance data between the laser and the top of the wing on which the reflector is mounted, the amount of real-time deformation at any point on the wing or fuselage is obtained. The amount of real-time deformation at any point on the wing or fuselage is calculated from the amount of data extracted from the wing deformation database. According to the theory of elastic thin plate, using the ideal two-dimensional beam as an example to illustrate the realization of the method, and the simulation shows. The method has universal significance and practical application value for measuring the elastic deformation of wing in real time.
