Abstract

The present invention relates to a method for producing propellant powder charges intended for heavy barrel weapons, such as canons and howitzers, and with a high degree of filling and a high energy content, and also to propellant powder charges produced in accordance with this method. The charges according to the invention are distinguished by the fact that 70 to 95% of their weight consists of a more coarsely grained powder and 30 to 5% consists of a granular powder with a smaller grain size. These two powders have the same of different chemical composition, and one or more of them can be surface-inhibited.

Claims (7)

1. Method for producing progressive propellant powder charges intended for barrel weapons and with a high degree of filling or loading density and thus also a high energy content at which the charge is produced by mixing at least two types of granular powder of different grain size, of which at least the powder type with the largest grain size and thus the most internal priming channels has a progressive burn characteristic, characterized in that as subsidiary components of the actual charge, granular powders are chosen whose size, geometric shape and quantities are adapted to give the smallest possible empty spaces between the powder grains.
2. Method according to Claim 1, characterized in that the starting material chosen for the charge comprises at least two types of powder whose mutual progressivity has been optimized for the particular purpose.
3. Method according to Claim 1 or 2, characterized in that the starting material chosen for the charge is granular powder of the same or different chemical composition but with different grain size and thus with a different number of internal priming channels.
4. Method according to any one of Claims 1-3, characterized in that, when choosing the starting material, powder types are chosen of which one or more are surface-inhibited.
5. Method according to Claims 1-4, characterized in that, of the powder types intended to be included 1. Method for producing progressive propellant powder charges intended for barrel weapons and with a high degree of filling or loading density and thus also a high energy content at which the charge is produced by mixing at least two types of granular powder of different grain size, of which at least the powder type with the largest grain size and thus the most internal priming channels has a progressive burn characteristic, characterized in that as subsidiary components of the actual charge, granular powders are chosen whose size, geometric shape and quantities are adapted to give the smallest possible empty spaces between the powder grains.

2. Method according to Claim 1, characterized in that the starting material chosen for the charge comprises at least two types of powder whose mutual progressivity has been optimized for the particular purpose.

3. Method according to Claim 1 or 2, characterized in that the starting material chosen for the charge is granular powder of the same or different chemical composition but with different grain size and thus with a different number of internal priming channels.

4. Method according to any one of Claims 1-3, characterized in that, when choosing the starting material, powder types are chosen of which one or more are surface-inhibited.

5. Method according to Claims 1-4, characterized in that, of the powder types intended to be included progressive and one or more can be surface-inhibited.

1. Method for producing progressive propellant powder charges intended for barrel weapons and with a high degree of filling or loading density and thus also a high energy content at which the charge is produced by mixing at least two types of granular powder of different grain size, of which at least the powder type with the largest grain size and thus the most internal priming channels has a progressive burn characteristic, characterized in that as subsidiary components of the actual charge, granular powders are chosen whose size, geometric shape and quantities are adapted to give the smallest possible empty spaces between the powder grains.

2. Method according to Claim 1, characterized in that the starting material chosen for the charge comprises at least two types of powder whose mutual progressivity has been optimized for the particular purpose.

3. Method according to Claim 1 or 2, characterized in that the starting material chosen for the charge is granular powder of the same or different chemical composition but with different grain size and thus with a different number of internal priming channels.

4. Method according to any one of Claims 1-3, characterized in that, when choosing the starting material, powder types are chosen of which one or more are surface-inhibited.

5. Method according to Claims 1-4, characterized in that, of the powder types intended to be included in the finished charge, all the types are introduced contemporaneously with each other, and at the same time the casing, cartridge or the like to which the powder is added and in which the charge is to be stored prior to use is subjected to vibrations which improve the degree of packing of the charge.
6. Propellant powder charge intended for barrel weapons, with a high degree of filling or loading density and with a high energy content and produced in accordance with the method according to any one of Claims 1-5, characterized in that it contains at least two different types of granular powder of which at least one type has progressive burn characteristics and in which one or more of these powders can be surface-inhibited, and in which the burn characteristics of these different powders are adapted to one another while their mutual grain sizes and the quantities of each powder included in the charge are adapted to one another such that the empty space which necessarily remains between the powder grains is as limited as possible.
7. Propellant powder charge according to Patent Claim 6, with a high degree of filling and with a high energy content, and intended for heavy barrel weapons, characterized in that 70-95% of its weight, preferably 75 to 85% of its weight, consists of more coarsely grained powder, such as a 19-hole or 37-hole powder cut into short sections, and 30-5% of its weight, preferably 25-15% of its weight, consists of a more finely grained powder, such as a 1-hole or 7-hole powder, and these two powders have the same or different chemical composition and at least one of them is progressive and one or more can be surface-inhibited.
