摘　　要：为了研究不同阻力器结构的增阻特性,设计了多种结构10个方案的某型迫弹一维弹道修正引信阻力器,测量了配用这些一维弹道修正引信阻力器的某型迫弹在零攻角、低风速下的空气阻力,计算了一维弹道修正迫弹的空气阻力系数及其相对于制式迫弹的增阻倍数,探讨了不同阻力器结构的增阻特性.当引信结构允许设计较大的增阻面积时,选用简单的平面阻力器结构较为合理.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 paper calculates the air drag index of 1D TCF and the increase in air drag relative to the standard mortar, it 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.
