Definitions
- the invention relates to a combustible ammunition molding, such as a propellant charge sleeve or a Propellant tank.
- High-energy propellants as required for firing performance-enhanced projectiles be, produce high temperatures and pressures in the corresponding barrel and lead thus also to an increased wear of the weapon barrel by erosion.
- the propellant powder talc, wax or a similar material admix it is known, the propellant powder talc, wax or a similar material admix.
- the erosion-reducing effect of such additives relative is low.
- US Pat. No. 3,426,684 discloses adding erosion-reducing additives to propellant powder WO 3 or MoO 3 . It is also mentioned in these references that in cartridges with a combustible propellant charge case, the erosion-reducing additives can also be introduced into the propellant charge case. On the other hand, further details on the proportion of substances to be introduced into the propellant charge tube can not be found in these publications.
- the invention is based on the object, an ammunition molding of a combustible material which contains erosion-reducing additives that provide a better erosive reduction Effect of propellant powder on the inner surface of a gun barrel caused as known comparable additives.
- the invention is based essentially on the idea that erosion-reducing additive 2 to 15% of an oxide of one of the rare earth elements, in particular La 2 O 3 , CeO 2 , Y 2 O 3 , or one of the elements of the sixth subgroup of the Periodic Table, in particular MoO 3 or WO 3 , or polyoxymethylene (POM) or a combination of these substances.
- tungsten trioxide WO 3
- the erosion on the inner surface of a corresponding barrel decreased by 47% over conventional ammunition in which no erosion-reducing additives were used in the propellant charge case.
- aqueous slurry of the starting material required for the preparation of the molding 2 to 15 wt .-% of one or introduced several erosion-reducing substances and then in a conventional manner then the molding (e.g., by applying a mandrel, etc.).
