摘要: 机动动作库是飞机空战仿真的重要基础,可靠的、具有针对性的机动动作库能够提高空战仿真的真实性和应用价值。为了建立具有针对性的机动动作库,提出了一种通过三维逆向建模进行气动特性计算再建立飞机机动动作库的技术途径,对气动参数未知飞机的空战仿真问题提供了技术支撑。首先,对飞机的几何外形进行了三维重建,计算分析了其纵向气动特性;然后,将气动数据加入飞行仿真的限制环节,设计了针对该型飞机典型战术动作的机动动作库;最后,基于MATLAB函数进行了机动动作的可视化研究。研究结果表明:机动动作库体现了对于飞机类型的针对性和可靠性,可视化实现了飞行轨迹和飞机姿态的三维显示及参数游标,为空战决策、空战仿真模拟训练和提高作战效能奠定了基础。

Abstract: Maneuver movements library is an important basis for aircraft air combat simulation. Reliable and targeted maneuver movements library can improve the authenticity and application value of air combat simulation. In order to establish a targeted maneuver movements library, a technical approach of calculating aerodynamic characteristics through 3D reverse modeling and then establishing the maneuver movements library of the aircraft is proposed, which provides technical support for the air combat simulation of aircraft with unknown aerodynamic parameters. Firstly, the aircraft's geometry was reconstructed in three dimensions, and its longitudinal aerodynamic characteristics were calculated and analyzed. Secondly, the aerodynamic data was added into the restricted link of flight simulation, and a maneuver movements library for the typical tactical movements of the aircraft was designed. Finally, based on MATLAB function, the visualization of maneuver movements was studied. The results show that the maneuver movements library reflects the pertinence and reliability of aircraft types, and visualizes the 3D display of flight trajectory and aircraft attitude and the parameter cursor, which lays a foundation for air combat decision-making, air combat simulation training and combat effectiveness improvement.

Key words: 3D reconstruction, aerodynamic characteristics, flight simulation, maneuver movements library, visualization
