A Study About Measuring System Of Cannon's Static Direction Angles

This paper introduces a static state directional accuracy of gun measuring technique, on this basement, we has used laser photo-electricity theodolite, and has designed the big gun's measuring accessory. And we have made a integrated test equipment successfully. Using this device, we can measure gun's height angle and level angle static state directional precision. And we analyzed the effect of the big gun erect axis incline trunnion axis is out of the vertical of the erect axis and the big gun axis is out of the vertical of the erect axis to measuring accuracy. This system's practicability is very strong. This testing instrument's successful development, not only did we know fairly well before shooting range ball firing, but it can instruct manufacture of artillery, make assure the quality of every artillery, save a great deal fund.
