摘要
在分析现有高空风探测误差来源的基础上,开展了高空风探测精度提升方法研究和基于棘面气球、300 g胶面小球和不同绳长的高空风探测精度提升对比试验。分析结果表明:由于钟摆效应、侧滑效应、导航定位精度、测风数据算法等原因,常规高空风探测数据存在较大的测量误差,通过调整探空气球和探测绳长,可以提升高空风探测精度。探测试验结果显示:棘面气球配1.2 m绳长和300 g胶面小球配4 m绳长的探测组合可以显著减小高空风探测过程中引入的随机误差,提高高空风探测精度,减小探测数据分层厚度,为后续航天发射任务高精度高空风探测保障提供科学的参考和依据。
In this paper,the sources of high-altitude wind detection errors are analyzed.Highprecision detection accuracy improvement methods have been studied.The comparative experiments on high-altitude wind detection using jimsphere balloon,300 g latex balloon,and balloons with different rope lengths are conducted.Due to factors such as the pendulum effect,skidding effect,navigation and positioning accuracy,and wind measurement data algorithms,conventional methods exhibit significant measurement errors.Adjusting the balloon and sounding line length can improve high-altitude wind measurement accuracy.As a result,The detection combination of jimsphere balloon with 1.2 m rope length and 300 g latex balloon with 4-meter rope length can significantly reduce the random errors introduced during the high-altitude wind detection process,improve the accuracy of high-altitude wind detection,and reduce the thickness of stratified detection data.The findings provide scientific references and bases for ensuring high-precision high-altitude wind detection for subsequent space launch missions.
