Abstract (en)
[origin: EP0150431A1] 1. A propellant charge for tubular weapons, characterized in that it consists of a mixture of at least one mono- or polybasic homogeneous propellant charge powder, of which the particles are of homogeneous material, with at least one heterogeneous propellant charge powder of which the particles consist of a mono- or polybasic base powder with mono- or polybasic powder granulates embedded therein and which, by virtue of its heterogeneous composition, has a pressure characteristic with a negative firing temperature coefficient ; in that the propellant charge powders are adjusted to the same or comparable characteristic values in regard to heat of explosion, force and dimensions ; and in that the mixing ratio between the propellant charge powders is selected so that, in a desired, predetermined nominal firing temperature range, the positive firing temperature coefficient of the homogeneous propellant charge powder is compensated by the negative firing temperature coefficient of the heterogeneous propellant charge powder to give substantially constant burning behavior of the propellant charge.
