摘要
为降低航天飞行器研制成本,提高研制效率,通过分析航天飞行器各阶段研制特点与验证需求,设计实现了一套可重用、可扩展的半实物总体性能仿真验证系统。该系统集成了飞行器导航/制导/控制、供配电、测控通信、结构机构、控制反推动力等系统模型,利用半物理试验技术、虚拟视景仿真技术和实物运动演示技术,在闭环状态下分析和验证总体大系统的综合性能和技术指标。仿真验证系统已在多个在研型号研制中应用,结果表明本系统运行稳定、可靠,实现方案合理,可以作为飞行器总体性能仿真验证的技术平台。
In order to reduce the development cost and improve the development efficiency, a set of reusable and extensible simulation system for semi - physical performance simulation is designed and analyzed by analyzing the characteristics and verification requirements of each stage of the space vehicle. The system integrates the system models of aircraft navigation / guidance / control, power supply and distribution, measurement and control communication, structural mechanism and control of reverse thrust. By using semi-physical test technology, virtual scene simulation technology and physical motion demonstration technology.Analysis and verification of the overall performance of large-scale integrated system and technical indicators. Simulation results show that the system is stable, reliable and feasible, and it can be used as a technical platform for the simulation and verification of the overall performance of the aircraft. The simulation verification system has been applied in many research models.
