Definitions

the guide tapes can e.g. B. made of copper, soft iron or plastic.
the projectile is particularly sensitive to radial pressure, since large stresses on the material can occur at points dependent on the projectile geometry.
the shell can u. a. are pressed inwards and the seal against the propellant gases usually guaranteed by the guide band is no longer guaranteed.
the present invention is therefore based on the object of specifying a projectile body of the type mentioned at the outset, in which, especially when using very thin-walled casings, there is a reduction in the mean guide band pressure and a better seal against the gas pressure.
the axial extent of the relief grooves depends on the rigidity of the shell and should be> 4 mm for artillery shells with metal guide bands.
Fig. 1 denotes a projectile body, 2 the projectile casing and 3 the guide band.
the guide band 3 is dimensioned so that it fully presses into the trains when the projectile passes through the tube. It transmits the swirl to the floor via the rail guide of the trains and at the same time seals against the powder gases.
the projectile 1 has a cavity 4 inside, in which, for. B. a brake parachute, not shown, can be accommodated.
Fig. 2, 2 again designates the projectile shell on which the guide band 3 according to the invention is arranged.
the grooves denoted by 31 to 34 serve in a known manner to accommodate the guide band material which also shears off at the rear when the projectile body passes through the tube.
the radial contact between the tube and the guide band 3 exists only at the guide band rings 36 to 41.
the dashed curve 300 shows the guide band pressure distribution for a guide band without grooves according to the storey structure with cavity 4 shown in FIG. 1. It can clearly be seen that a maximum guide band pressure occurs approximately in the middle of the guide band.
the width B should be between 6 and 20 mm, depending on the type of the projectile. However, it should be taken into account that the total width of the guide band rings in such projectiles should be approximately 20 mm (typically, guide bands have a width of 38-40 mm).
the step curve 301 in FIG. 3 gives approximately the pressure distribution of the guide belt 3 according to FIG. Fig. 2 again. Due to the relief groove 35, the guide band pressure drops significantly in this area.
