虚拟试验中临近空间大气环境仿真技术研究
|
摘要
临近空间作为空天过渡区域,对火箭等各种飞行器的安全和准确入轨有重大影响。为了完善临近空间的虚拟试验验证平台,提出一种基于美国TIMED卫星的SABER探测数据和参考大气模式的虚拟试验环境资源构建方法。该方法使用Matlab读取和预处理SABER探测数据,利用SABER探测数据的压强和密度参数计算大气风场,通过三维离散点插值算法构造符合分辨率要求的大气环境模型,根据SE D RIS规范格式化大气环境数据,生成临近空间虚拟环境资源。测试结果表明,该方法生成的临近空间虚拟大气环境资源能够为虚拟试验验证平台提供相应的环境支撑。
As an aerospace transition area, near space has a significant impact on the safety and accuracy of various aircrafts such as rockets. In order to improve the virtual test verification platform in the environment resources, a method for constructing virtual experimental environment resources based on SABER detection data of the US TIMED satellite and reference atmospheric model is put forward. Matlab is used to read and preprocess SABER probe data, the atmospheric wind field with pressure and density parameters of SABER detection data is calculated, an atmospheric environment model that met resolution requirements is constructed through three-dimensional discrete point interpolation algorithm, and atmospheric data is formated according to the SEDRIS specification to generate near space virtual environment resources. The test results show that the virtual space environment resources generated by this method can provide corresponding environmental support for the virtual test verification platform.
