High-speed motion analysis system could record images up to 12,000fps and analyzed with the image processing system.
The system stored data and images directly in electronic memory convenient for managing and analyzing. The high-speed
motion analysis system and the X-ray radiography system were established the high-speed real-time X-ray
radiography system, which could diagnose and measure the dynamic and high-speed process in opaque. The image
processing software was developed for improve quality of the original image for acquiring more precise information.
The typical applications of high-speed motion analysis system on solid rocket motor (SRM) were introduced in the
paper. The research of anomalous combustion of solid propellant grain with defects, real-time measurement experiment
of insulator eroding, explosion incision process of motor, structure and wave character of plume during the process of
ignition and flameout, measurement of end burning of solid propellant, measurement of flame front and compatibility
between airplane and missile during the missile launching were carried out using high-speed motion analysis system.
The significative results were achieved through the research. Aim at application of high-speed motion analysis system on
solid rocket motor, the key problem, such as motor vibrancy, electrical source instability, geometry aberrance, and yawp
disturbance, which damaged the image quality, was solved. The image processing software was developed which
improved the capability of measuring the characteristic of image. The experimental results showed that the system was a
powerful facility to study instantaneous and high-speed process in solid rocket motor. With the development of the
image processing technique, the capability of high-speed motion analysis system was enhanced.
