    • The present invention relates to an apparatus for measuring a muzzle velocity of a fired bullet so that the bullet may explode at an accurate location. The muzzle velocity measuring apparatus includes a detector configured to comprise a pair of cores encircled by probe wound coils and installed in two separate positions in an adapter, and to output a muzzle velocity signal based on eddy current signals which are generated by the probe wound coils when a bullet fired from a bullet chamber passes through the adapter, a muzzle velocity calculator configured to calculate a flight speed of the fired bullet based on the muzzle velocity signal; and a transmitter configured to transmit the calculated flight speed to the bullet.
      The transmitted data may be used by a controller integrated in the bullet to correct the preset time of explosion.
      The cores of the coils may have a U-shape.
    • 本发明涉及一种用于测量发射子弹的枪口速度的装置,使得子弹可能在准确的位置爆炸。 枪口速度测量装置包括检测器,其被配置为包括由探针缠绕线圈包围的一对芯体,并且安装在适配器中的两个分开的位置中,并且基于由探针缠绕线圈产生的涡流信号输出枪口速度信号 当从子弹室射出的子弹通过适配器时,枪口速度计算器被配置为基于枪口速度信号计算被击发的子弹的飞行速度; 以及发射机,被配置为将所计算的飞行速度传输到子弹。 所发送的数据可以被集成在子弹中的控制器使用以校正预设的爆炸时间。 线圈的芯可以具有U形。
