舰载机飞行仿真可视化研究

航空母舰的研究主要分布在舰载机的起降方式及飞行甲板的布置上,仅仅通过理论分析这些过程是很难发现问题的,提出了飞行可视化研究;基于高层体系结构(HLA)仿真平台搭建整个舰载机的飞行仿真系统,并利用MultiGen Creator/ Vega和VC 的虚拟现实仿真平台实现了舰载机飞行仿真全过程的可视化,论述了多自由度(DOF)三维模型的建立、视景仿真系统的软件设计、坐标转换、数据平滑等关键技术,给出了三维仿真结果.应用结果表明,该仿真系统结构合理可靠,可逼真地演示舰载机的整个飞行过程,成为验证舰载机的调度、导引、控制等算法的正确性和有效性的有效手段.

Research on Visualization of Flight Simulation for CarrierAircraft

The research of aircraft carrier is centralized on aircrafts' taking off, approaching, landing and laying on deck. It's difficult to discover problems only through theoretic study. Visualization of flight simulation becomes necessary for researcher. Based on HLA, a flight simulation system for the CarrierAircraft was developed. The software platforms of MultiGen Creator/ Vega and VC were used to realize 3D visualization of the whole flight process of CarrierAircrafts. Some key technologies were introduced, such as creation of Multi-DOF 3D model, software design for visual simulation system, coordinate transfer, data smoothing etc. Some 3D frames were proposed to show that the simulation system is reasonable and reliable, which can realistically demonstrate the simulation process of CarrierAircrafts. This simulation system has been successfully applied to validate the correctness and practicability of scheduling, guiding and control algorithm.
