Abstract

The embodiment of the invention provides a rocket dynamic power fragment field testing method and device, and relates to the technical field of ammunition power tests. The method comprises the following steps of: laying a galvanized iron wire net to form a grid target, wherein the grid target comprises a plurality of grids used for marking a fragment position A (x0, y0, 0) of a rocket; establishing a ground coordinate system OXYZ and a projectile coordinate system OdXdYdZd, and determining a coordinate conversion relation formula from the ground coordinate system OXYZ to the projectile coordinate system OdXdYdZd; and determining the dynamic scattering angle phi and the fragment ray center angle eta of a fragment according to the fragment position A (x0, y0, 0) of the rocket and the coordinate transformation formula. The method and the device can calculate and evaluate the dynamic scattering angle phi and fragment ray center angle eta of the fragment under dynamic conditions, wherein the killing area of the fragment of the rocket can be intuitively determined according to the fragment ray center angle eta.

Description

technical field [0001] The invention relates to the technical field of ammunition power testing, in particular to a method and device for testing the dynamic power fragmentation field of a rocket. Background technique [0002] In actual combat, the ground anti-personnel grenade and rocket warhead mainly rely on the fragments generated after the explosion to kill the target. The purpose and significance of the power test is to obtain various parameters related to the power of the tested ammunition through the test, so that we can compare the effect of the ammunition on the target. According to the power of a certain ammunition, it can be determined whether its power meets the tactical technical indicators and whether it meets the design requirements; it is also possible to compare the power of two different ammunition through the power results to determine which design is more reasonable. Determine the best solution. [0003] The power test is generally divided into two cat...
