Problems solved by technology

[0004] When measuring with the existing three-point measurement method, the caliper may not be level, causing measurement errors
In addition, because only three points are taken on a section of the arc, the value is less, the processing error of the projectile itself, the roughness of the surface and the inherent slope of the projectile arc itself may affect the accuracy of the measured value
Therefore, the accuracy of the radius of curvature of the projectile obtained by the existing three-point measurement method needs to be verified.

Description

technical field [0001] The invention relates to the field of projectile parameter measurement, in particular to a device and method for measuring the radius of curvature of the arc portion of a projectile. Background technique [0002] Ammunition static measurement is an important part of ammunition preparation, and the measured data are some basic parameters of the ammunition itself. In the conventional weapons shooting range test, especially when the product performance is found not to meet the requirements in the test, the calculation data in the static measurement of ammunition is an important basis for analyzing the cause of the problem, and some calculation data are also an important basis for product performance evaluation. [0003] At present, the measurement of the radius of curvature of the projectile arc usually uses a single height gauge combined with a single caliper, and only three position data on the arc of the projectile are measured, and then the radius of ...
