摘要
在使用激光跟踪仪进行数据测量的基础上,建立新的测量系统对CESSNA172 飞机垂直尾翼倾斜角进行测量,以获得精确的测量数据.该文采用灰色预测模型预测CESSNA172 飞机的垂直尾翼倾斜角与飞行时间的对应关系.经验证,灰色预测模型可以有效地预测CESSNA172 飞机垂尾倾斜角随飞行时间的变化规律,且模型预测精度高.
Abstract
On the basis of using a laser tracker for data measurement,a new measurement system is established to measure the vertical tail tilt angle of the CESSNA172 aircraft and obtain accurate measurement data.The grey prediction model is used to predict the corresponding relationship between the vertical tail tilt angle and flight time of the CESSNA172 aircraft.After verifi-cation,the grey prediction model can effectively predict the variation of the vertical tail inclination angle of CESSNA172 air-craft with flight time,and the model has high prediction accuracy.
