Abstract
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 TCP) for a mortar shell, and 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 paper calculates the air drag index of 1D TCP and the increase in air drag relative to the standard mortar, and discusses the characteristics of increase in air drag for different structures of the damper. It is concluded that selecting a plane damper structure is more reasonable when the fuze structure allows larger increase in its area.
