【摘要】 势平衡理论的初速或然误差的模拟方法,建立在火药动静态燃烧的不均一性参量π与π’成正比,即π=θπ’的物理推断的基础上.该文通过三种七孔药的动静态燃烧试验,验证了该推断的正确性,并证实了火药的初速或然误差与其动静态燃烧的不均一性参量π、π’成正比的规律.更多还原

【Abstract】 The method for estimating the statistic deviation of muzzle velocity with thetheory of potential equilibrium for interior ballistics is based on the deduction on the di-rect relationship between the dynamic and static parameters π and π’ showing burningnon-uniformity of the propellants,that is π= θπ’.According to the dynamic and staticcombustion tests on three types of 7-perforated propellants,the paper verifies the cor-rectness of the deduction and shows that the statistic deviation of muzzle velocity γ_v0 isdirectly proportional to π and π’.更多还原
