This spatial configuration is caused mainly by air drag, but the exact form of the curve is complicated to calculate.

In studying the characteristics of increasing drag for different damper structures, the paper gives several structures and ten schemes for the damper of one-dimensional trajectory correcting fuze (1D TCF) for a mortar shell, measures the air drag on the mortar munition installed with one-dimensional trajectory correcting fuze under 0 degree nutation angle and low wind speed.

The earth rotation and the air drag force are both influencing to the kinematics of a projectile.

The kinematics of an east horizontal projectile in the northern hemisphere are both influenced by the air drag force and the earth′s rotation.

In order to comprehensively discuss the kinematical equation and the expression for drift of a projectile in the northern hemisphere, the influence of the earth ratation and the air drag force are both considered.
