预报风强度对火箭最大气动载荷精度影响及建模分析
Influence of forecasting wind intensity on rocket maximum aerodynamic load accuracy and modeling analysis
摘要
Abstract
In order to solve the problems of very few research literatures on the accuracy of different forecast wind intensity and the corresponding accuracy of the maximum aerodynamic load forecast value,the accuracy characteristics of different forecast wind intensity and the corresponding maximum aerodynamic load forecast value were respectively analyzed on the basis of the actual wind in a certain area,and the multiple linear regression method was used to establish a revised model.The results show that within 1～11 days of forecasting days,the greater the forecast wind intensity,the higher the forecast wind accuracy and the corresponding maximum aerodynamic load forecast value accuracy.Using the multiple linear regression method can improve the accuracy of the maximum aerodynamic load forecast,and the smaller the forecast wind intensity,the more obvious the improvement of the forecast accuracy of the maximum aerodynamic load.These findings have reference value in the flight assurance and safety decision-making of rocket launch.关键词
