    • A projectile suitable for firing from a gun barrel contains an additive which is dispensed along the gun barrel by the pressure of a gas propellant so as to reduce barrel wear.
      A charge of additive (11) is stored within a cylindrical recess in the rear face (12) of the projectile. In use, the pressure of the gas propellant acts on a nylon piston (6) sJidably located within the tube (2), which piston in turn pressurizes the charge (11) forcing it forward through the four extrusion ports (9) to the exterior of the projectile.
      The charge of additive (11) is preferably a mixture of a thermal insulator and a lubricant, best characterised by silicone oil or a paste mixture of titanium dioxide and silicone grease. The invention is particularly applicable to small arms bullets for firing from a rifled gun barrel, and may be incorporated in existing hollowed bullets, for example tracer bullets.
    • 适用于从枪管射出的射弹包含添加剂,其通过气体推进剂的压力沿枪管分配,以减少枪管磨损。 添加剂(11)的装料被存储在弹丸的后表面(12)中的圆柱形凹部内。 在使用中,气体推进剂的压力作用在可滑动地位于管(2)内的尼龙活塞(6)上,该活塞反过来加压了装料(11),使其向前穿过四个挤出口(9)到外部 的射弹。 添加剂(11)的加料优选是绝热体和润滑剂的混合物,其特征在于硅油或二氧化钛和硅油的糊状混合物。 本发明特别适用于从膛枪枪射出的小武器子弹,并且可以结合在现有的中空子弹中,例如示踪子弹。

    • A projectile includes a leading end formed by a tip having an ogive configuration, a trailing end formed by a frusto-conical base, and a cylindrical mid-section interconnecting the tip and the base. A first annular shoulder is formed where the tip meets the cylindrical mid-section and a second annular shoulder is formed where the mid-section meets the base. A metallic band abuts the second annular shoulder and a third annular shoulder is formed where the metallic band meets the cylindrical mid-section. A trailing end of a thermoset polymer guide band abuts the third annular shoulder and a leading end abuts the first annular shoulder. The thermoset polymer guide band conforms to the shape and size of the cylindrical mid-section. The thermoset polymer guide band may be impregnated with barrel treatment chemicals so that the barrel is cleaned and lubricated when the projectile is fired.
    • 抛射体包括由具有凹凸构造的尖端形成的前端,由截头圆锥形基部形成的后端和将尖端和基部互连的圆柱形中间部分。 形成第一环形肩部,其中尖端与圆柱形中间部分相接触,并且形成第二环形肩部,其中中间部分与基部相接。 金属带邻接第二环形肩部,并且形成第三环形肩部,其中金属带与圆柱形中间段相交。 热固性聚合物引导带的尾端邻接第三环形肩部,并且前端邻接第一环形肩部。 热固性聚合物引导带符合圆柱形中间部分的形状和尺寸。 热固性聚合物导引带可以用桶处理化学品浸渍,使得当抛射体被发射时,筒被清洁和润滑。
