| 摘 要： | 一堆弹道修正引信阻力器空气阻力的简捷测量，是在弹丸零攻角、低风速下测量空气阻力的试验方法．测量系统由压力传感器、悬挂装置、试验弹、风速产生设备，等组成．当悬挂试验弹吹风产生时。压力传感器输出电压将变化。通过阻力与压力转换关系可得出试验弹的空气阻力。并计算出空气阻力系数．对改装PP87式82mm迫击炮弹的空气阻力对比测试，该方法与风洞试验、计算机仿真结果趋势相符．

| Abstract: | The air resistance of damper of 1-dimension trajectory correcting fuses (1-D TCF) is measured under pill angle of attack and low wind speed. Measure system consists of pressure sensor, hanging equipment, test shell and device engendered wind speed. When blowing wind toward Hanging test shell, output voltage of pressure sensor can change, the air resistance of test shell can be obtained by changing relation of air resistance and pressure, air resistance coefficient can be also calculated. The air resistance of PP87-82mm mortar shell refitted with 1-D TCF was compared with the air resistance of test shell, the wind tunnel experiment and the computer simulation result shows that change trend of air resistance of refitted shell and test shell is consentaneous. |
