Abstract
An improved gun barrel in a tank cannon assembly having a recoiling mass is described. This gun barrel has an increased target impact precision by virtue of stabilizing the bending oscillations and/or vibrations during firing, thereby making the jump angle more uniform from one firing to the next one. The L/D ratio of the gun barrel is larger than 52 (where L represents the length of the gun barrel and D represents the caliber diameter). The gun barrel jacket has a frusto-conically shaped portion extending from the muzzle towards the rear of the gun barrel which is adjoined by a cylindrically shaped portion. The gun barrel is supported on a cradle along the latter portion. The gun barrel exhibits a continuous unbuckled bending line in its static and dynamic conditions between its muzzle and the cylindrical jacket portion. The frusto-conically shaped and cylindrically shaped portions merge into each other and have identical diameters along their merging line. The cylindrically shaped jacket portion is supported with respect to the firing direction along a distance a which is <7 D. The center of gravity of the recoiling mass is disposed within the frusto-conically shaped jacket portion of the gun barrel.
