摘要： A cooling fin for a mortar tube comprises a plurality of discrete nibs disposed on an external surface of the mortar tube wherein the nibs are arranged in longitudinal rows spaced circumferentially around the mortar tube. Preferably, the number of longitudinal rows of nibs is thirty-six. The nibs have a substantially square cross-section.

摘要： A finless mortar tube made of a superalloy includes, seriatim, a breech end, a beginning taper point, an ending taper point, a lower clamp region, an upper clamp region, and a muzzle end. The nominal wall thickness of the tube is constant from forward of the breech end to the beginning taper point and the nominal wall thickness of the tube decreases from the beginning taper point to the ending taper point. The mortar tube is capable of a substantial increase in the rate of fire compared to conventional mortar tubes.
摘要翻译： 由超级合金制成的无油砂浆管包括串联，后膛端，起始锥形点，终止锥形点，下夹持区域，上夹持区域和枪口端部。 管的标称壁厚从后膛端的前端到起始锥形点是恒定的，并且管的标称壁厚从起始锥点到终止锥度点减小。 与常规的砂浆管相比，砂浆管能够显着提高火焰发生率。
