Definitions
- the invention is concerned with a reinforced active mass container for a projectile by incorporating a rib construction in the lid of the active mass container, in particular by cold forming.
- Projectiles and in particular smoke projectiles of different caliber are constructed so that different and / or multiple active bodies are carried along in the projectile or projectile casing. These, in turn, are constructed to include a body of caulk having a bottom, a support tube and a lid.
- DE 10 2008 019 752 A1 discloses an active body for a submunition with active agents, which has an insulating layer between a heat-body container and a pyrotechnic composition.
- the WrkMech constituer can be closed by a cover with a blow-out.
- a projectile of superimposed submunition is known.
- the submunition contains a Wrasse mass that rests on a ground.
- the submunition body shell is seen in the weft direction provided with a lid. Between the lid and the Wrkmasse at least one biasing body is involved. This has the task of being able to better absorb the launching load and the high angular momentum that act on the projectile and thus on the submunitions.
- the invention has as its object to show a simple way that the shooting loads, etc., which act on the projectile and the WrkMech, also can absorb well.
- the problem is solved by the features of claim 1.
- Advantageous embodiments are listed in the subclaims.
- the invention is based on the basic idea to reinforce the active mass container by a rib construction and to incorporate the ribs or stiffeners, in particular in the lid of the active body or Wrkmassen employers whose length preferably over the entire radius of the lid.
- Another approach is to manufacture the control agent tank differently in terms of production in order to achieve solidification of the container material.
- metal cold forming has proven to be the preferred method. Cold forming is the forming of metals at a temperature well below the recrystallization temperature. The material is so heavily loaded until it melts and occupies a fiber structure. As a result, the material strength is increased by increasing dislocation density in the material. With the method, a work hardening of the container material is possible. This in turn allows the use of a material with better machinability at lower processing costs. Alternatively, casting could also be used.
- the ribs can be made in the manufacture according to the load size, eg short or long ribs to the outer diameter of the active mass container. Due to the metal cold forming or the casting technique also the rib geometries can be varied. Furthermore, a noncritical base material can be used in terms of processing and tempering. The chip removal rate on the blank is minimized and fewer parts are needed.
- the container construction is simplified by dispensing with screw connections with adhesive protection and shrink / press fits.
- a built-in safety device with centering function is integrated by extending a support tube of the body and a corresponding recess in the bottom area.
- FIG. 1 is a perspective view of a partially cut active body
- Fig. 2 is another perspective view of another active body.
- an active body or Wirkmassen investigatinger 1 is shown, which consists essentially of a container 2 with lid 3 and an incorporated in the container 2 active mass 4.
- the lid 3 has in addition to ribs 5 at least one exhaust opening 6.
- Lid 3 and ribs 5 form a structural unit, in which case the ribs 5 extend from the central tube (support tube) 7 with the firing bore 8 up to the outer edge 1.1 of the container 1.
- the ignition bore 8 may be a bore that extends around the central tube 7.
- a kind of sealing washer 9 is introduced. From below, the active body 1 is closed by a bottom plate 10.
- Fig. 2 shows an active mass container 20, which consists essentially of the same parts as the active body 1, but in the lid 23 has ribs 25 which extend only a portion 22 around the central tube 7 and less expiring, i. Losing their height, pass into the lid 23.
- the functioning of the body 1, 20 is known. After firing a bullet not shown in detail from a gun barrel also not shown at a predetermined time the Wirkmassen notioner 1, 20 from the floor driven. About the central or middle raw r 7 and the firing hole 8 while the active mass 4 is ignited and the reacted active mass 4 blown through the exhaust opening (s) 6.
- a sealing element for example, an O-ring or metal seal
- the active mass container 1, 20 with a reinforcing rib construction 5, 25 is preferably produced by cold forming.
- the central tube 7 is itself preassembled in the Wrkassen notioner 1, 20.
- the connection between the two is made by a press / shrink connection.
