BALLOTING IN A FRENET FRAME
This paper presents a concise model of projectile Jump with a set of formulae for the mathematical description. This model provides explanations for unpredictable features of Jump like Occasion to Occasion Error. The distinctive aspect of this model is the conversion of deflecting vibration of tube to a moving coordinate system using Frenet Frame of Differential Geometry. Equations of motion of the projectile were formulated with vector functions using path-length as an independent variable in this coordinate system. Validity of this model was demonstrated with a right cylinder. This model highlights the concept of Balloting-Phase Shifts which leads us to the selected factors against variability of Jump and of Variability Zone. The formulae listed here are so basic and sound that they can be applied to many types of projectile for jump calculation.
