摘要
通过建立导弹气动数据库,改进检索策略,利用插值算法和模糊查询的方法,对导弹气动特性数据库进行检索,并将检索结果应用于某再入弹头气动力、热、烧蚀及弹道实时耦合仿真过程的可视化,实现了快速、准确的查询目标,解决了长期以来气动力数据,弹道表面热环境数据,烧蚀外形数据的零散、管理困难、使用不便等问题,为导弹设计、模拟飞行提供更快捷,方便的气动资料。
By establishing missile aerodynamic database,improving retrieval strategy,using interpolation algorithm and fuzzy query method,the database of missile aerodynamic characteristics is retrieved.And the retrieved results are applied to visualization of aerodynamic,thermal,ablation and ballistic real-time coupling simulation process of a reentry warhead.The fast and accurate query target is realized,and the long-term aerodynamic data and ballistic data are solved.Surface thermal environment data,scattered ablation profile data,difficult management,inconvenient use and other issues provide more rapid and convenient aerodynamic data for missile design and flight simulation.
