真实飞机各部件的运动状态总是和理论状态存在差异,所以在飞机型号研制和试验试飞过程中,掌握飞机的实际运动状态是开展后续工作的基础,而由各种仪器测量结果来分析真实运动状态存在着许多困难。以某型号飞机的襟翼转角分析为例,从激光跟踪仪所测得的结果,分别通过圆模拟法和二面角法来分析襟翼在各卡位下的转角。并对两种方法进行详细的介绍和分析,以寻求合理的方法来消除测量误差、制造误差及结构变形对测量结果的影响,供后续工作的开展实施。
The actual state of the aircraft’s movement is always different from that of the theoretical state. Therefore, in the course of developing and testing aircraft types, it is the basis for follow-up work to grasp the actual movement state of the aircraft. The measurement results of various instruments analyze the real movement Status there are many difficulties. Taking the analysis of the flap angle of a certain type of aircraft as an example, the turning angle of the flaps under each card position is analyzed respectively by the circular simulation method and the dihedral angle method from the results measured by the laser tracker. The two methods are introduced and analyzed in detail in order to find a reasonable method to eliminate the influence of measurement error, manufacturing error and structural deformation on the measurement results for the follow-up work to be carried out.
