【Abstract】 Under the internal grooves, the projection angles of aimable warhead were investigated through Taylor angle approximation. The author has derived the formula of projection angles: δ=k 1(L/D) k 2 arctan [v 0 sin (θ 2-θ 1)/2D e] . The formula are quite consistent with the experimental results in fragment density.更多还原
