Abstract

The invention relates to a breakaway projectile displacement speed testing sensor, belonging to a testing sensor used for testing the displacement speed of a projectile in the whole ejection process.The testing sensor mainly solves the technical problem that the existing knotmeter can not test the displacement speed of the high speed projectile in the ejection process. The technical scheme for solving the technical problem comprises: the breakaway projectile displacement speed testing sensor consists of a breakaway steel wire tester, a coupler and a photoelectric encoder, wherein the breakaway steel wire tester is connected with the photoelectric encoder by the coupler. The testing sensor has the advantages of simple structure, convenient installation, being capable of accurately testingthe displacement and the speed of the tested projectile in the whole ejection process, etc.

Description

Technical field [0001] The invention relates to a pull-off type projectile displacement speed test sensor, which belongs to a test sensor for testing the displacement speed of the projectile during the entire ejection process. Background technique [0002] In order to understand the changing law of the displacement speed of the projectile during the movement, it is necessary to test the displacement speed of the high-speed projectile during the ejection process. However, the existing various speedometers cannot measure the displacement speed of the high-speed projectile during the ejection process. test. Therefore, in order to obtain the changing law of the displacement velocity of the high-speed projectile during the movement, it is urgent to design a sensor for testing the displacement velocity of the projectile. Summary of the invention [0003] The purpose of the present invention is to solve the technical difficulty that the existing velocimeter cannot test the displacement ...
