After the airdrop experiments of the system of the projectile and speed-down parachute, the balance velocity obtained from the optics apparatus on the ground、the balance spinning speed obtained from the gyroscope on the projectile and the image obtained from the infrared detector on the projectile are all used to simulate the six-dimension exterior trajectory of the projectile and identify the roll damping moment derivatives, and the identification can safely come to a conclusion that the absolute value of roll damping moment derivatives from the engineering calculation are on the low side.

对卷弧尾翼弹与减速伞系统进行空投试验，由地面光测系统给出平衡落速、弹上陀螺给出平衡转速、弹上红外探测器拍摄地面图像判断弹的姿态。通过六自由度弹道模拟，对弹滚转阻尼导数进行参数辨识，得到工程估算所得滚转阻尼导数绝对值偏小的结论。 5。对空投试验中出现弹姿态摆动现象，从受力分析及红外图像分析两个方面进行探讨，给出合理解释，并根据分析对弹外形进行修改，在后来的试验中收到很好的效果。

The most difficult situation for deployment is the negative spin (no forward speed and low vertical speed), whereas, for example, a spiral dive autorotation speeds up parachute deployment.

抛备份伞最糟糕的的状况是在倒水平螺旋（没有前进速度，低的垂直下落速度）下，而高速螺旋中，由于旋转速度很高，备份伞可以很快的打开。
