摘要
本文从飞机六自由度全量方程出发,计算、模拟了JJ-5飞机失速/尾旋特性和各种改出尾旋的方法,对JJ-5飞机特技机动飞行及其相应的尾旋特性进行了计算分析;并把计算结果和试飞结果进行了比较,结果表明数值计算与试飞基本上符合,结合计算机实时成像技术,对相应的计算结果进行了动态实时显示,显示结果直观、逼真,可望运用于有关尾旋飞行训练中.
In this paper, the characteristics of stall and spin of JJ-5 are simulated by solving six-degree-of-freedom differential equations. The flying aerobatics and its spin characteristics are also studied. The result from the simulation is compared with the result from flying test. The digital simulations can be transformed to digital images which can be displaied on the screen. The images are audio-visual, true to real flying and may be practically used to spin flying trainning in future.
