Abstract
A case for use with a propellant charge has a substantially cylindrical envelope. The envelope is formed from a combustible material. At least one support, that is formed from a combustible material, is coated to a substantially uniform thickness on at least one reception section with an anti-wear additive. A mechanism, formed from a combustible material, positions the support relative to the envelope such that, after assembly, at least one empty space is defined between an inner surface of the envelope and the anti-wear additive.
Claims3
A case in combination with a propellant charge, the propellant charge disposed within a substantially cylindrical envelope that is formed from a combustible material, comprising:
- at least one support that is formed from a combustible material and coated on at least one reception section with an anti-wear additive;
- and
- means for positioning the support spaced from the substantially cylindrical envelope such that, after assembly, at least one empty space is defined between an inner surface of the envelope and the anti-wear additive, the means for positioning being formed from a combustible material;
- said means for positioning comprising a radial stop defined by a plurality of sticks of propellant charge between said inner surface of said substantially cylindrical envelope and said at least one support.
