Acoustic emission testing is one of the most common and effective non-perishable test methods that allow testers to collect data and provide accurate propellant results. Acoustic discharge occurs when an object is under pressure or due to holding a heavy load or from extreme temperature changes, heat stress, cold cracks, melting, bond failure, and fiber are sources of acoustic discharge. The sensors used to record acoustic emissions use piezoelectric material. The effects of various parameters on the combustion rate of solid propellants are discussed and reviewed. The preferred method of overheating heat reduction techniques is acoustic extraction as it is very simple, fast, expensive, and can be performed with 98% accuracy. However, with a more accurate burn rate using BEM. BEM, however, requires a large amount of propellant. So, in everyday practice, the acoustic extraction method is well used by geothermal scientists worldwide. The craw ford bomb is the oldest method of temperature measurement, the only one that is most suitable for double base propellants with an accuracy of 97 to 98%. Advanced technologies such as closed bombs, ultra-noise measurement, microwave, x-ray, and plasma power, etc. While the chimney-type laser method is very complex but naturally boring further with various diagnostic methods such as x-ray, method of -flash, and pressure. The capture method, the servo method measurement method, and the high-speed motion detection method to determine erosion are also important.
Literature ReviewGarima Gupta et.al studied the combustion rate of solid propellants, whether stable or solid, under a variety of conditions operating conditions are very important for the use and application of important reasons. The average burnout rate is web
