Projectile rotating band
WebNov 26, 2024 · 1. Introduction. During the launching process of the artillery, the engraving process of the projectile rotating band is a highly nonlinear, transient dynamic process involving instantaneous impact, material failure and damage, and large geometric deformation, and has a great influence on many interior ballistic parameters, such as the … WebFeb 12, 2016 · Meanwhile, new processes for joining the rotating band on the projectile body have also to be developed because of different material physical properties. In this paper, swaging, welding, and newly developed spraying technologies for fabricating rotating band are analyzed, respectively.

The rotating band has three essential functions: Center the rear end of the projectile in the gun barrel.Seal the bore to prevent burning powder gas from moving through the rifling grooves past the projectile.Engage with the rifling of the barrel to spin the projectile and stabilize its flight. See more A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling … See more Driving bands pre-cut for the rifling have been used for muzzle loaded weapons, e.g. some mortars. Freely rotating bands can be used to reduce the spin imparted to the round as is … See more • Big Bullets for Beginners See more The shell is stabilized for yaw in the barrel by a smaller bourrelet band near the front of the projectile. This band keeps the projectile travelling straight in the bore supported by the … See more • Obturation • Sabot (firearms) • Rotating gas-check See more WebFeb 15, 1985 · Rotating or driving bands are bands of relatively soft materials surrounding a projectile. They have a number of functions the chief of which is probably that they produce stabilizing rotation of the projectile when they are “engraved” or keyed into the rifling.

WebIn this case, the rotating band model and mesh are both built in ABAQUS in order to meet the requirements of CEL simulation. The simulation results include the deformation process of the rotating band, the motions of the projectile, the dynamic engraving resistance and the calculating efficiency were obtained, compared and analyzed. WebMar 1, 2024 · Chen and Leach modelled barrel–projectile interaction in a rotating band by using ABAQUS program. Siewert measured small caliber engraving force by push test. It was found that small caliber engraving is a more complex relationship. Siewert and Cytron assessed the influence of small caliber rifling designs on bullet engraving forces by ...
