Definitions
- the invention relates to a shootable from a gun barrel projectile, which at least has a circumferentially arranged on the projectile guide band.
- a segmented sabot for a subcaliber Projectile known in which to reduce the erosion of the corresponding gun barrel in the rear-side part of each of the sabot segments at least one radially arranged Recess is provided which opens into a guide band and in the one pipe wear-reducing additive is introduced. Also in this case the pipe wear must be reduced Additive by the gas pressure of the propellant gases after appropriate Warming of the additive are pushed out of the radial recesses, what again requires a relatively complex construction of the respective sabot.
- the invention has for its object to provide a projectile of the type mentioned, in which when firing the bullet an erosion-reducing effect of Gun barrel occurs without the need for a pressure source is required.
- the invention is based essentially on the idea of a plastic existing Guide tape to use, which contains an erosion-reducing additive, not by the pressure of the propellant gases, but by the firing of the projectile At the inner surface of the weapon barrel occurring abrasion of the guide band released becomes. Due to the decomposition enthalpy required for this, the system becomes heat withdrawn and cooled the pipe inner wall. This abladierende effect then leads to Reduction of the erosion of the barrel.
- ceria CeO 2
- tungsten trioxide WO 3
- POM polyoxymethylene
- 1 denotes a part of the outer wall portion of a projectile, which is located in a dashed line indicated gun barrel 2.
- a guide band 3 made of plastic (for example, PA 12) in a groove-shaped recess 4 arranged.
- the guide band 3 contains in its outer, ie the gun barrel 2 facing surface region 5 an erosion-reducing additive 6 (for example, CeO 2 ).
- an erosion-reducing additive 6 for example, CeO 2
