基于HLA的载人航天器飞行任务仿真平台研究与实现

         

摘要

面向载人航天器飞行任务仿真需求,根据载人航天器的特点以及高层体系结构(HLA)技术,提出了基于高层体系结构的载人航天器飞行任务仿真平台方案,设计实现了由运行管理、飞行指令、数据记录、数据可视化等功能,以及涵盖轨道、姿态、能源、动力学等多个专业仿真模型组成的仿真平台,给出了应用实例,并就仿真平台开发中的联邦开发过程、仿真模型接口软件、飞行场景三维可视化等关键部分进行了探讨.与单一的飞行任务仿真软件相比,该分布式仿真平台覆盖的专业面更全,验证内容更丰富,可扩展性更强.随着载人航天器系统飞行任务复杂程度的提高,通过对仿真平台的扩展和重用,可适应新的任务验证需求.该仿真平台可为复杂载人航天器的飞行任务设计验证提供依据,并对基于HLA的其他航天器仿真系统的联邦设计与开发具有一定的参考价值.%According to the requirements of the manned spacecraft flight mission simulation, we propose a solution of the flight mission simulation platform for the manned spacecraft based on the characteristics of the manned spacecraft and the principles of the High Level Architecture(HLA), and realize the functions including the simulation management, the flight commands, the data recording, the data visualization, and implement the simulation platform which consists of those items for orbit, attitude, power, dynamics, etc. A typical application case is given, together with some key technologies including the platform development process, the three-dimensional visualization of the flight scene, and the software interface of the simulation model. Compared with the single flight mission simulation software, this platform covers more aspects of related fields and verification contents, and is more extendable for future updating. With the increasing complexity of the manned spacecraft flight mission, the simulation platform can meet new mission verification requirements by extending and reusing the current components. The simulation platform can be used for the verification of complex manned spacecraft flight mission designs, and it is also useful for the future simulation platform design and the development of other HLA-based spacecraft simulation systems.
