迫击炮弹10有一个流线型可分离头罩18,该头罩18遮护着一个半球形红外整流罩32,它与陀螺稳定的红外导引头20装配成一体.在迫弹飞行的初始上升阶段,流线型头罩18在其原来位置,而且可展开弹翼26保持在弹体内,此时迫弹10具有与常规迫击炮弹相类似的气动特性.随后头罩18被抛掉,同时弹翼26展开,以抑制迫弹10的旋转.响应来自红外导引头20的指令,喷气控制装置22作动,操纵迫弹10去攻击目标12的顶部,该目标是靠使用导引头20所选择的.
The mortar 10 has a streamlined detachable headgear 18 which shields a hemispherical infrared cowling 32 which is integral with the gyro-stabilized infrared seeker 20. During the initial ascent phase of the forced-air flight, the streamlined hood 18 is in its original position and the deployable flaps 26 remain within the projectile with the projectile 10 having aerodynamic characteristics similar to conventional mortar shells. The hood 18 is then thrown away while the flaps 26 are deployed to inhibit the rotation of the bombs 10. In response to an instruction from the infrared seeker 20, the air injection control device 22 is activated to operate the projectile 10 to attack the top of the target 12, which target is selected by using the seeker 20.
