Ultrasonic technique, is one of the best nondestructive techniques for solid propellants motors evaluation. In this article ultrasonic technique use, has been reported for measuring solid propellant burning rate at different pressure with just one experiment and at the moment, for especial motors. The use of swept frequency method in a proper confine frequency and interrupted frequency method has been investigated for seperate specification liner-propellant and liner- case respectively. Ultrasonic device characteristic and way of working with that has been reported in order to investigate the micro cracks and micro cavities which cause to lowering mechanical properties and increasing burning surface and pressure and at last cause to motor explosion. In addition, the studies showed that in cold disposal of aged solid propellant motors, the case temperature is cooled till lower glass transition temperature (Tg) limits of binder and then by ultrasonic waves with 2 MHZ, is disposed. Also, in order to unity distribution of nano particle in mixture of slurry the ultrasonic mixer is used.
