Definitions

  • the invention relates to a body axially attachable to an artillery shell with a functional part designed as a radar reflector.
  • a body is known, for example, from DE utility model 7934250: this document describes that the radar reflector can be attached to the floor of the projectile as an additional component and can be fastened thereon by means of screws.
  • this type of fastening is safe and simple, it requires drilling holes and cutting threads in the floor of the storeys and therefore appropriate preparation, which must be carried out in a workshop.
  • a sleeve which is rotationally symmetrical about a longitudinal axis and is intended to be plugged onto the projectile is arranged on the functional part.
  • an artillery projectile of the usual type is designated by 1.
  • a first radar reflecting body 2 has a base 3, which, as described in DE utility model 7934250, is designed as a multiple triple mirror reflector.
  • a sleeve 4 is formed, which is intended to be plugged onto the pin (rear part) of the projectile.
  • a second radar reflecting body 5 has a sleeve 6 which is intended to be plugged onto the bow tip (bow part) of the projectile, while - not visible in the drawing - the front part 7 of the body 5 as a radar reflector, for example as a Fresnel Lens or designed as a Van Atta reflector.
  • the two bodies 2 and 5 are each designed to be rotationally symmetrical about a longitudinal axis 8, 8 ', the longitudinal axis 8, 3' coinciding with the longitudinal axis of the projectile when plugged in.
  • the two bodies 2 and 5 are also shown in FIG. 1 as bodies which are rotationally symmetrical about the longitudinal axis 8, 8 '; Variants with rotationally symmetrical, but not rotationally symmetrical bodies are also described below.
  • the body 2, which is designed as a multiple triple mirror reflector, consists of metal, for example of brass, or of the aluminum alloy mentioned in DE utility model 7934250.
  • the body 5 designed as a Fresnel lens or as a Van Atta reflector is, for example, in two parts with a sleeve 6 made of brass or aluminum alloy and a plastic such as epoxy or polyurethane resin existing front part 7, which is coated in a manner known per se to form a Fresnel lens or a Van Atta reflector with a metallic layer pattern (for example made of copper or aluminum).
  • a variant of a radar reflecting body to be plugged onto a projectile is shown in section.
  • This body is made in one piece from metal, but a base part 21 and a sleeve 22 can be distinguished.
  • the bottom part 21 also forms the radar-reflecting functional part; for this purpose it is designed as a multiple triple mirror reflector of the type described in DE Utility Model 7934250, which is shown in the drawing by the cutting boundaries 23 and 24.
  • the entire body is designed to be rotationally symmetrical about an axis 25, while the sleeve 22 is designed to be rotationally symmetrical about this axis 25, specifically in such a way that it can be fitted onto the projectile pin in a precisely fitting manner.
  • an adhesive layer 27 is provided on the inner surface 26 of the sleeve 22, which is shown thicker in the drawing than it actually is.
  • This adhesive layer 27 consists, for example, of a plastic layer made of epoxy or polyurethane resin, to which an abrasive, for example powdered corundum, is added in order to increase the static friction between the surfaces of the inside of the sleeve and the outside of the projectile or the projectile pin.
  • the sleeve 22 is provided on its inner surface 26 with beads 31 or claws 32 which fasten the sleeve on the projectile stud as soon as the sleeve is pressed onto the stud.
  • Both the beads 31 and the claws 32 can also run rotationally symmetrically about the axis 25 on the entire inner surface 26, but they can also be formed merely as individual lugs arranged in a rotationally symmetrical manner on the inner surface 26, for example in the form of 6 each offset by 60 ° about the axis 25, measured on the circumference in each case about 5 0 long claws, as shown in Fig. 4 in section of the sleeve 22 at the level of the claws 32.
  • a radar reflecting body to be plugged onto the arch tip of a projectile is shown in section.
  • the entire body is rotationally symmetrical about the axis 51.
  • the sleeve 52 made of metal is glued to a radar-reflecting functional part 53 made of plastic.
  • Electrically conductive strips 55 are attached to the outer surface 54 of the functional part 53, which cooperatively form a Fresnel lens.
  • the inner part 56 of the sleeve is shaped in such a way that it fits exactly on the arch tip of the projectile.
  • the inner part 57 of the functional part 53 is provided with a corresponding recess for receiving the top detonator of the projectile.
  • a detonating cord is provided in a bead arranged essentially rotationally symmetrically about the axis 51, the ignition of which after the sleeve has been fitted onto the projectile in a manner known per se by pressing on and optionally by explosive welding or electric discharge welding, a positive connection of the Causes sleeve 52 with the arch tip of the projectile.
  • the beads 31 and claws 32 shown in FIGS. 3 and 4 can also be designed such that they can be welded to the projectile stud by means of electrical discharge welding.
  • FIG. 6 shows a half section of a radar reflecting body 63 to be plugged onto the projectile pin and an explosive device 60 arranged thereon.
  • the body 63 is attached to the projectile by the method known as "explosive welding".
  • the body 63 is made in one piece from metal, its bottom part 64 is designed as a multiple triple mirror reflector, which is represented in the drawing by the cutting boundaries 70 and 71.
  • a sleeve 65 of the radar reflecting body 63 has an annular groove 66 on its outer side 73.
  • the explosive device 60 consists of a housing 68 which is rotationally symmetrical with respect to the axis 61 and which is filled with explosive 67.
  • the explosive 67 is ignited by means of a plurality of detonating cords 69 which are embedded in a body 72 made of rigid foam. Due to the explosive action, the sleeve 65 is severed at the location of the groove 66, as a result of which the sleeve 65 is terminated in a straight line.
  • the radar-reflecting body 63 Before the radar-reflecting body 63 is explosively welded onto a projectile, its rear is cleaned and degreased with solvent and rubbed off with an emery cloth. The body 63 is then placed with the explosive device 60 on the rear of the projectile and the explosive 67 is ignited, preferably from a distance.
