Hump speed and efficiency are directly affected by Space interval control of rolling cut.

According to the system concept and plan of hypervelocity kineti cenergy missile,on the condition of satisfying tactic-technical specifications,the different precise computing model of the general parameter has been established in allusion to each thrust-velocity plan,and the program is finished by using Numerical Integral & Dichotomy.

Based in the companion paper, Fuzzy Analysis method of the quality of bending tubes has been modified according to actual production experience, which makes testing of the guality of bending tubes more conform to reality, and fuzzy optimal design method of heating temperatme and pushing velocity was proposed, which makes optimal design of the prorccess parameters more strightward.
