Influence of the initial velocity of the projectile on the kinematics of the projectile

The work uses a mathematical model for determining the frontal air resistance to movement of projectile, which based on solving inverse problem dynamics. Knowing flight range at certain angles aiming given in firing tables, functional dependence force projectile its speed and other factors is determined, taking into account effect weight Coriolis force.
 It has been established that, depending angle, during can combine stages with supersonic,transonic, subsonic, decreasing or increasing speeds. Therefore, drag determined each stage separately.
 influence initial velocity deviation from nominal value OF-462ZH fired 122-mm D-30 howitzer, charge investigated. Depending speeds.
 was found that displacement values coordinates zeroing point trajectory basis proposed model, are almost same modulus when deviates by +∆V0; tabular displacements point, general, large magnitude theoretical; greatest discrepancy between them achieved an angle 45o00’; determination values, theoretical tabular, real, possible field tests.
