METHOD FOR CALCULATING A RIFLE ANGLE CAPABLE OF MINIMIZING THE MAXIMUM VALUE OF RIFLE FORCE GENERATING IN LAUNCHING

摘要

PURPOSE: A method for calculating a rifle angle is provided to accurately calculate boundary conditions at a starting point and an end point of a rifle angle and to calculate the optimal rifle angle in which the maximum value of rifle force is minimized.;CONSTITUTION: A method for calculating a rifle angle is as follows. A rifle angle as a factor of rifle force is developed and calculated like a predetermined equation to calculate to minimize the maximum value of the rifle force generating between a bullet and a rifle when the bullet moves in the inner wall of a gun barrel. The difference of the rifle angles between the end point of a rifle and the starting point of the rifle among the calculated rifle angles is less than 5.5 degree. The rifle is an uneven portion which is projected from the inner wall of the gun barrel to allow the bullet to rotate. The force generating between the bullet and the rifle when the bullet moves on the inner wall of the gun barrel is the rifle force.;COPYRIGHT KIPO 2012
