Abstract
In this paper, a wire condition inspection system was developed using a high-speed camera and a spectrometer to inspect the state of diamond wire used in the cutting operation of a rocket motor in real time. During the cutting process, there is a risk that the propellant inside the rocket motor may be ignited due to excessive frictional heat of the diamond wire and sparks caused by wire breakage. At low speed, it is possible to measure wire wear using a high-speed camera and spectrometer, and at high speed using a spectrometer. Using the results of this paper, it is expected that it will be very usefully applied to the performance evaluation of guided munitions.
