Definitions
- the invention relates to an ammunition article according to the preamble of the claim 1.
- Such an ammunition article is disclosed in US 4,371,875 A. on the local Fig. 4 as a circular slot antenna modified dipole antenna described in the detonator tip of a projectile, which is obvious as an antenna, so as a sensor, for a radar distance fuze is designed.
- the inner conductor passes through a concentric through the frusto-conical fuze tip extending coaxial line whose flattened End face, on the free Stimende in turn a hollow frustoconical metallic hood to carry as a microwave resonator.
- Their larger base holds a slight clear axial distance to An igniter tip, which latter with another hollow frustoconical Hood to the tuned to the antenna frequency decoupling the igniter body is provided.
- An ammunition article of another kind is known from WO 99/02936 A2 as a drop bomb with im Center of her stern arranged, sandwich or patchy satellite antenna known.
- a drop bomb with im Center of her stern arranged, sandwich or patchy satellite antenna known.
- Final phase control namely by matching between the coordinate predetermined target point and the geodetic actual position of Ammunition articles to increase the accuracy of accuracy.
- Such an antenna configuration is for ammunition in the form of about Artillery bullets, however, impractical. Because of the tail antenna ago approximately symmetrical to the projectile longitudinal axis to backward oriented antenna directional characteristic would be for the most part of the stretched ballistic Flight to the horizon, at the beginning even below it, and after the apogee only slightly above it. This is the probability of multiple Navigation satellites at the same time for a quick and precise determination of the path point to be able to receive the path correction sufficiently trouble-free, rather low.
- the present invention is therefore the based technical problem, one after the type of artillery projectile along a substantially horizontally stretched trajectory spent ammunition equipped with an antenna that has a favorable directional characteristics for receiving satellite navigation information.
- annular bead or torus-like electromagnetic radial optionally something still front receiving characteristic in front of the circumferential slot and thus to promote in the vicinity of the hollow truncated cone, are at a radial distance to the inner slot opening, oriented transversely to the slot and thus coaxial to the longitudinal axis, a cylindrical metallic reflector wall and between them and the inner slot opening in both axial directions, ie by means Deckund Base plate arranged metallically closed cavity.
- This antenna to a receiving circuit are at equidistant from each other staggered positions along the circumferential slot feeders two-pole, preferably coaxial cable with their outer and mecanicleitem, on the two mutually axially opposite edges of the opening into the cavity inner slot opening connected.
- For the supply cable is at this respective coupling-out approximately axially parallel through the bottom plate of the cavity along the inner circumferential surface of the outer wall of the hollow truncated cone introduced to him.
- the cavity is divided transversely to the longitudinal axis to form a ring of an electrical as poor as possible conductive material increased dielectric constant, the independent of frequency and temperature as possible also by low dielectric Losses and high creep resistance distinguishes, such as the fluorine-containing Polymer to be able to insert PTFE (polytetrafluoroethylene) under trade names we are Teflon, Fluon or Hostaflon on the market.
- PTFE polytetrafluoroethylene
- a hollow truncated cone-shaped height section of the detonator tip 13 is a round-slot antenna 18 for receiving satellite navigation information for the Course control of the projectile 12 designed. Their lateral surface 19 closes bug and The rear side practically infinitely to the conical surface of the remaining igniter tip 13 on.
- the slot 20 of this antenna 18 is in the wall 21 of a Hollow body of electrically conductive material, preferably light metal such Aluminum, formed and lies concentrically in a cross-sectional plane to Longitudinal axis 16.
- the outer opening 22.1 of the slot 20 is located in the lateral surface 19 of the wall 21.
- the opposite inner opening 22.2 of the Slit 20 is located opposite to a longitudinal axis 16 coaxial, cylindrical Reflector wall 23.
- the wall 21 of the hollow truncated cone and the reflector wall 23 are at an axial distance from the inner slot opening 22.2 by metallic coaxial annular bow and stern cover plates 24.1, 24.2 in the respective cross-sectional plane to the longitudinal axis 15 connected to each other, the thus at the same time the small or the large base of the frustoconical Represent circular slot satellite antenna 18. So is between the mutual radial cover plates 24.1, 24.2 on the one hand and the walls 21, 23 on the other delimited hollow cylindrical hollow space 25 delimited, the reflector wall 23 at the same time the outer wall of the central channel 17 and the is opened by the slot 20 to the outside.
- the cavity 25 is approximately in the center plane of the slot 20 divided to a thick-walled hollow cylindrical ring 26 of electrically non-conductive material with a dielectric constant that is significantly higher than that of air, to insert, such as PTFE such as Teflon.
- the round slot antenna 18 via at least one feed cable 28, which is shown here as a coaxial cable.
- a feed cable 28 which is shown here as a coaxial cable.
- a coaxial cable Preferably are several, at least three or four, such Auskoppelstellen 29 for connection of feeder cables 28 equidistant distributed over the circumference of the slot 23 intended.
- At each one is at least two-core cable 28 through a hole 30 in the rear cover plate 24.2 of the annular cavity 25 therethrough inserted parallel to the longitudinal axis 16 along the outer wall 21 in this.
- the one conductor 28.1 possibly the coaxial outer conductor, is in the inner opening 22.2 of the slot 20 at the rear edge 31.2 of the antenna 17 connected.
- access channels 33 are inclined relative to the longitudinal axis 16 and the slot plane 20 of the lateral surface 19 ago in the wall 21 of the hollow truncated cone Round slot antenna 17 introduced.
- 31 tools can be introduced through these channels be a clamping tool, a soldering iron or directly radiation or Line heat very targeted to be soldered coupling points 29 and there to the Front ends of the conductors 28.1, 28.2 be introduced.
- the invention may also be provided for at the coupling points 29, e.g. clamps prepare to take effect when the conductors are fed.
- Such access channels 33 which after assembly with pasty electrically conductive Material can be closed, run under as large as possible Angle relative to the transverse plane of the circumferential slot 20 to at the outer opening 22.1 in the lateral surface 19 as much undisturbed metallic Leave material for the electric slot effect, ie in Interest in a possibly undisturbed concentric, slightly radially oriented ahead Ringwulstförmigen response characteristic of the circular slot antenna 17th
- an ammunition article 11 is equipped with an antenna 18, due to the all around more uniform, radially even something from the oriented annular bead-shaped Torus characteristic a trouble-free reception of satellite navigation information even if he is in the manner of an artillery projectile 12 spent under twist along a stretched ballistic trajectory out, out of which is a tail antenna with spherical characteristics no good reception conditions as high as possible above the horizon standing navigation satellites.
- the igniter tip is now 13 of the projectile 12 with a designed as a round-slot satellite antenna 18 Hohlkegelstumpf made of electrically conductive material such as light metal, in which a coaxial annular cavity 25 through a radial to the projectile longitudinal axis 16 circumferential annular disc-shaped slot 23 to the igniter shell surface 19 is open.
- Feeder cables 28 are uniform over the circumference distributed with its signal and ground conductors 28.2, 28.1 at the inner mouth 22.2 of the slot 20 connected to the cavity 25 back to the slot walls 31.
