[Abstract]:With the development of virtual test technology, atmospheric environment is an important part of the integrated natural environment (Synthetic Natural Environment,SNE), and its modeling and simulation technology has become an important technology in the field of virtual experiment at home and abroad. The purpose of this project is to construct the virtual atmospheric environment resources in the range of aeronautical space (altitude 0-20km) and adjacent space (20km-100km). The virtual atmospheric environment resources, which include temperature, pressure, atmospheric density, and some components of the atmosphere, are provided for the virtual test. They conform to the SEDRIS (Comprehensive Environmental data representation and Exchange Specification). It can provide virtual test 0-100km height range virtual atmospheric environment test resources for the joint test platform developed by Harbin University of Technology and Technology. It is of great significance to improve the fidelity of virtual experiment and expand the application space of virtual atmospheric environment resources. This paper aims at the demand of virtual atmosphere environment in the application of aerospace virtual experiment, and in order to improve the deficiency of using the air environment resources before, the operation is complicated and the space range is small. The overall scheme of constructing virtual atmospheric environment resources in 0-100km space range is designed, and the modeling of atmospheric environment is studied. For aeronautical space, the idea of constructing atmospheric environment based on MM5 (Mesoscale Model Version 5) model is followed, and the operating configuration software of Linux version is developed, which simplifies the operation of MM5 mesoscale atmospheric model and improves the efficiency of data generation. In addition, the atmospheric models such as NRLMSISE-00 are studied to increase the atmospheric density and some elements of atmospheric components on the basis of the original elements of atmospheric environment. For the adjacent space, the method of constructing atmospheric environment resources based on the original atmospheric environment data of SABER detector on TIMED satellite is proposed. The near space atmospheric environment resources are constructed by data preprocessing, interpolation algorithm calculation and so on. In order to express the atmospheric environmental data completely and clearly and to exchange the general lossless data, the related technology of SEDRIS is studied, and the atmospheric data is expressed as the STF data in accordance with SEDRIS. Based on the research of related technologies and methods, the overall scheme of constructing 0-100km virtual atmospheric environment resources is designed, and the overall requirement analysis of the project is given. According to the demand analysis, the MM5 mode configuration and operation control software is developed. The related software, such as aeronautical space atmospheric data generation software, near space virtual atmosphere environment resource construction software, virtual atmosphere environment resource synthesis service software, etc. The static and dynamic models of each software are designed by using the object-oriented idea. The software is designed and developed on the Qt Creator and Visual Studio platforms, and the functions of the software are tested. The combined test platform of the laboratory and the virtual test platform of a certain unit are used to verify the application, which can provide the atmospheric environment resources for the virtual test, and show that the design of the scheme is reasonable. In line with the subject of 0-100km virtual atmospheric environment resources construction needs.
