Definitions
- the invention relates to a spin-stabilized artillery projectile according to the preamble of claim 1.
- Such an artillery shell is, for example, from the DE 40 00 167 C2 known.
- the famous floor has one several guide grooves with ring grooves on the floor to the floor towards a plastic sealing ring that is also referred to as an obturator ring.
- This sealing ring serves to improve the sealing of the Bullet against the high pressure propellant gases and is usually non-positive by shrinking attached to the floor.
- the present invention is based on the object spin-stabilized artillery shell of the type mentioned Specify the type in which damage or destruction or wiping the sealing ring when inserting the projectile safely prevented in the cargo space of the corresponding weapon and its sealing function is not adversely affected.
- the invention is based on the idea that Not to arrange the sealing ring behind the guide band, but to embed it in an annular groove of the guide band. This makes it reliable against mechanical damage protected and practically impossible to strip.
- the defined seating of the sealing ring in the groove is guaranteed an improvement and a higher reliability of the sealing function and thus a reduction in pipe wear.
- the figure shows the cross section of a spin-stabilized according to the invention Artillery level 1 in the area of his example guide belt made of copper 2.
- Das Guide belt 2 is set in the direction of the longitudinal axis 3 of the Storey 1 seen - from three web-shaped guide band parts 4-6 together, between which there are two annular grooves 7, 8 are located.
- the ring groove 8 is made of polyamide 6.6 existing sealing ring 9 arranged, which is in a groove-shaped recess 10 of the projectile wall 11 extends and with this is positively and / or non-positively connected.
- the sealing ring itself is made with oversize and on one Point separated, the ends of the separation point such beveled that they are superimposed on the desired inner and outer diameter.
- the sealing ring is then in the expanded ring groove of the guide tape and the superimposed Permanently seal the ends of the sealing ring with a suitable adhesive connected.
- the invention is of course not based on the above described embodiment limited.
- Guide band and sealing ring instead of copper and Polyamide also consist of other suitable materials.
- the annular groove for the sealing ring does not have to be mandatory located in the middle part of the guide band, but can also be at another point on the guide band be introduced.
