Jbm ballistic. Things To Know About Jbm ballistic.

Kinetic energy is a function of the bullet mass and motion. This motion involves the velocity and rotations. It is represented by the following equation. KE = 1/2 M v 2 + 1/2 I w 2. NOTE: this assumes a single rotational axis and forward motion of the bullet. For multiple rotations and non-symmetric bodies, things get a little more complicated.The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet.if no adjustment is desired, input zeros 240 rem for rmatch and hmatch, and the trajectory will be run with 250 rem the input elevation angle. 260 rem the program solves the trajectory by numerical integration 270 rem using the heun method, which is an iteratively applied 280 rem second order predictor-corrector technique.There is anecdotal evidence that (1) plastic-tip or hollow-base bullets may have larger errors, and (2) the velocity correction above 3600 ft/sec may predict faster twists than needed. Improvement must await new twist-stability factor data. Don Miller 2862 Waverly Way Livermore, CA 94551 [email protected] the CD & KD discussion, the vector equations of motion are. d u /dt = -k v ( u - w ) + g. where. k = p s C D / (2 M) If we assume that g is in the z direction only and the only wind is a cross wind (| w | = w x) then the first equation can be rewritten as three equations. du x /dt = -k v ( u x - w x )
