立式风洞是研究飞机尾旋与尾旋改出的特种设施。由于尾旋试验模型的大小受限于风洞的试验段尺寸和流场的边界条件,较难在模型内部安装测量系统,早期均采用外部系统对处于螺旋运动状态的飞机模型姿态进行捕捉、辨识,进而分析飞机的尾旋特性与改出特性。随着材料科学、智能加工技术和信号传输技术的发展进步,测量系统向模块化、微型化和超微型化发展,使得测量机构能够安置于飞机模型的内部,这样不仅可以实时测量数据并记录,不需要到试验后才进行判读和辨识,而且所测量的数据更加完整。
Vertical wind tunnel is to study the tail rotation and tail rotation out of the special facilities. Because the size of the tail spin test model is limited by the size of the experimental section of the wind tunnel and the boundary conditions of the flow field, it is more difficult to install the measurement system inside the model. Early, the external system was used to capture and identify the attitude of the aircraft model in a spiral motion state. , And then analyze the tail rotation characteristics and characteristics of the aircraft. With the development of materials science, intelligent processing technology and signal transmission technology, the measurement system has been developed to be modular, miniaturized and ultra-miniaturized so that the measurement mechanism can be placed inside the aircraft model so that not only the data can be measured and recorded in real time, Interpretation and identification are not required after testing, and the data measured is more complete.
