In this paper, solid rocket fuel titration by non-destructive ultrasonic test, using ultrasonic laser receptor technology. This technique is one of the modern ways to receive ultrasound, this technology works by making a three-dimensional image of heterogeneous cracks. Taking into account mainly the storage temperature ranging from 50 to 70 C and the casings in which the rocket fuel is placed. Experiments were carried out on plastic and stainless steel covers. The thickness of plastic casings ranges from 16 to 17.5 mm. The thickness stainless steel ranges from 9 to 20.40 mm. The important scientific contribution of this research is testing the storage of rocket fuel at high temperatures and knowing what happens by introducing rocket fuel in the case of storage at those temperatures. To take into account the good ventilation system for solid rocket fuel.
