许多炮弹,尤其是用发射管发射的自推进炮弹都安装尾翼,炮弹一旦离开发射管后,尾翼就展开。为了达到尽可能高的命中精度,当炮弹离开发射管后最好使这种尾翼尽快地展开。本发明从事研究一种安装尾翼的自推进炮弹,其尾翼至少有三个配置在轴上的翼面,此时炮弹后面的轴按排在与弹轴平行的和与弹轴垂直的法兰盘之间。该炮弹突出的优点是:尾 Many rounds, especially self-propelled rounds fired from launch tubes, are equipped with empennages that once deployed leave the launch tube and the tail is deployed. In order to achieve the highest possible accuracy of hitting, it is best to expand the tail as soon as it leaves the launch tube. The present invention is directed to a self-propelled projectile mounted empennage having at least three airfoils disposed on the shaft of the tail, at which time the shaft behind the projectile presses against a flange parallel to the projectile and perpendicular to the projectile between. The outstanding advantages of this shell are: tail
