先进战斗机大迎角运动特性分析和试验

High Angles of Attack Character Analysis and Test for an Advanced Fighter

描述了先进战斗机大迎角气动数据库的结构,介绍了使用全局稳定性理论对大迎角特性的预测分析结果和控制律的设计逻辑,之后进行了六自由度仿真计算,并根据飞行品质模拟器评价试验和自由飞试验结果对大迎角运动特性和控制律设计逻辑进行了验证。

This paper introduces the structure of aerodynamic data base in HAOA, and uses the bifurcation analysis and catastrophe theory method to predict and analysis the global stability for a advanced fighter. Then six degree freedom simulation has been done for a lot of check case, special for stall, spin, etc. The third, through flying quality simulation with pilot in loop and free drop model tests, the above design result is certificated.
