摘　　要：依据设计的一维弹道修正引信平面阻力器改装的某型迫弹(简称"一维修正迫弹")空气阻力的简捷测量试验数据,分析了一维弹道修正引信平面阻力器与"一维修正迫弹"的空气阻力、空气阻力系数的关系及影响,推导出其扩增空气阻力系数与一维弹道修正引信平面阻力器展开时的面积之间关系的数学模型,从而建立了一种定量计算"一维修正迫弹"的空气阻力系数和空气阻力的理论方法。According the data of the protable measuring to air drag of refitting some mortar munition(the refitting mortar)by design dragdevice of onedimensional trajectory correcting fuses(1D TCF),This paper analyses the relation and the influence of the plane dragdevice with its air drag and air dragindex,and establishes the mathematical model of its enlarging air dragindex relation to the spreading acreage,consequently set up a academic means to calculate the air dragindex and the air drag of the munition.
