摘要
Abstract
Using the aerodynamics theory,the mathematical model of the exterior ballistics decaying characteristic of rotating rate is set up for the projectile with the quasi-parabola nose borderline,and some examples are numerically solved by the Matlab. The credibility is veryfied by the coefficient of polar damping moment got from the Fluent. The value of the rotating rate of the projectile with the quasi-parabola nose borderline calculated by the theoretical model is close to the calculation results of the J Les Kim correction formula and the index formula,and the maximum relative error is less than 18%. The results can be used as a reference to the design of the fuze centrifugal self-destroying performance and the armor penetration warhead spin-resistant performance.关键词
