Abstract:
The steady flow field of a canard missile on different angles of attack and Mach numbers were studied. Based on analysis, a method was proposed to reduce the calculation for the rolling characteristics of the canard missile with free-spinning tails, and was tested to obtain the relations between rolling moment coefficient, Mach number, and angle of attack. All the computed rolling moment coefficients obtained from the proposed method greatly agreed with the experimental results of FD-06 wind tunnel in CAAA, which proved that the method can not only reduce the calculation cost but also keep precision in calculating the rolling characteristics of canard missiles.

一种自旋尾翼鸭式导弹滚转特性的计算方法

刘平安,刘明远

(哈尔滨工程大学 航天与建筑工程学院,哈尔滨 150001)

创新点说明:

通过对固定尾翼的鸭式导弹进行数值模拟,提出一种新的方法计算同种型号的自旋尾翼鸭式导弹的滚转特性,计算结果表明该方法保证了准确性的同时,可以达到大幅度减小计算量的目的,具有实用价值。

研究目的:

在保证计算精度的同时,减小自旋尾翼鸭式导弹的滚转特性在传统的非定常计算模式下的计算工作量与工作时间。

研究方法:

对固定尾翼鸭式布局导弹的外部流场进行定常的数值模拟研究,根据各组件的滚转力矩特性,定量计算该型号鸭式导弹在自旋尾翼下的滚转特性,并将计算结果与风洞试验数据进行对比验证。

研究结果:

用此方法算得的该鸭式导弹在自旋尾翼下的滚转力矩系数与自旋尾翼鸭式导弹的风洞实验数据结果吻合较好。

结论:

用此方法计算自旋尾翼鸭式布局导弹的滚转特性,在保证了准确性的同时,可以达到大幅度减小计算量的目的,具有实用价值。
