Therefore,due to the presence and the growth of these micro‐fractures along the service life of the solid rocket propellants can cause cohesive critical cracks take place during the ignition phase,these cracks increased the area of the burning surface lead to an out‐of‐design state.To study these phenomena,the aging program developed in was applied to eval‐uate the aging mechanisms involved in the accelerat‐ed aging program at 70℃for 90 d.The relation be‐tween the normal and accelerated aging program is represented in Table 4 and given in detail in the pa‐per of Bohn[14].
