飞机在飞行的不同阶段,机翼受到的气动载荷在随时发生变化,机翼上的活动面由于空间姿态变化大,载荷的变化尤其剧烈,如何在多体动力学模型中精确模拟气动载荷,一直是困扰飞机设计人员的一个很大的问题,利用多体动力学仿真软件中的编程语言,编制了活动面气动加载程序,极大的提高了气动载荷模拟精度和建模效率。
At different stages of the flight, the aerodynamic loads on the wing change from time to time. Due to the large changes in the space attitude and the dramatic changes in the loads on the airfoils, how to accurately simulate the aerodynamic loads in the multi-body dynamics model Is a big problem that plagued aircraft designers. Using the programming language in multi-body dynamics simulation software, a program of moving surface aerodynamic loading was programmed, which greatly improved the simulation accuracy and modeling efficiency of aerodynamic loads.
