专利要点在回转式支座上装有弹翼(弹翼在第一个位置上构成一个直径比弹径大的炮弹座,在第二个位置上构成阻力很小的控制机构)的次口径炮弹的特点是:在两个用挡块限制的位置中间的T形支座(9)[不安装弹翼(12)]可绕旋转轴(8)与翼面平行地并与弹轴(A)垂直地转动。在第一个位置上弹翼(12)构成一个角锥体,其尖端是朝后的[从炮弹(2)飞行方向看], Patents The utility model relates to a sub-caliber shell of a rotary bearing which is provided with an elastic wing (the elastic wing forms a projectile with a diameter larger than the diameter in a first position and a control mechanism with a small resistance in a second position) Characterized in that a T-shaped seat (9) [without mounting flaps (12)] in the middle of two stop positions limits can be arranged around the axis of rotation (8) parallel to the airfoil Turn. In the first position, the wing (12) forms a pyramid whose tip is rearward [seen from the direction of the shell (2) flight],
