Definitions
- the invention relates to a cross-slit powder according to the Preamble of claim 1.
- Bar powder according to the preamble are known from EP 0 304 099 B1 and EP 0 304 100 B1 known.
- the cross section of the bar powder is rosette-shaped and has spaced, continuous transverse slots with lying therein Holes or axial bores.
- DE 295 08 229 U1 describes an ignition unit for propellant charges known, arranged in the roller-shaped powder body on a flame guide tube are.
- the powder bodies have annular incisions over their entire length for predetermined breaking point formation.
- the invention solves this problem according to the characterizing features of claim 1.
- the slots dimensioned according to the invention cause a uniform Ignition of the propellant powder is also achieved in the slots and that The swaths can flow off.
- a rod powder 1 with a circular cross section has a diameter 2 by 14.5mm and a length 3 by about 400mm. Because of the seven, axial bores 5 arranged uniformly in cross section 4 a so-called seven-hole powder.
- the rod powder 1 has slots 6 lying transversely to the bores 5.
- the width 7 of the slots 6 is 0.2 mm and the length 8 8.5 mm.
- the diameter 10 of the axial bores 5 is 0.6 mm.
- the dimensions mentioned depend on the weaving thickness 13 of the bar powder and are calculated according to rule of thumb.
- the weave thickness 13 is the distance between two adjacent holes 5.
- a focal front 12 extends over the entire cross section 4 and strides in the direction of arrow 15, that is, in the axial direction.
- the combustion gases occur both on the focal front 12 as well as on the nearest slot 6 or slots 6. The gas pressure is therefore reproducible over the entire burn-off length.
- the spacing 22 of the slots 6 can be as small as desired. However, it does exist an upper limit. This is a maximum of 60 times the diameter 10 of the Holes 5, in this case 30mm. This distance 22 also helps that a controlled burn is achieved.
- any Cross-sections such as hexagonal, rosette-shaped or with ribs are possible.
- the invention relates generally to bar powder regardless of the number of holes 5, a nineteen-hole powder is mentioned as an example.
- the rod powder 1 is from the medium caliber, for example from 25mm to large caliber applicable.
