Definitions

  • the invention relates to a sabot according to the preamble of claim 1.
  • a generic drive cage is known from US-A-2 998 780. Between the segments, circumferential slot-shaped spaces are provided for the wings of the stabilizing tail. In order to enable a rear-side seal despite the gaps, a plate-shaped traction sheave element is provided. At the front, the segments are attached in their rear areas by means of tabs and bolts. At the front, the segments extend radially outwards and thus form a front first support with a pocket-shaped inner surface for the air flowing in when exiting the weapon barrel, with the cooperation of which the sabot should be separated from the projectile. The traction sheave element forms a second support on the rear.
  • each segment has a relief bore in addition to the slots that extend to the front. This is intended to reduce the pressure which can build up during the weft development and when passing through the tube as a result of propellant gases flowing past the traction sheave on the outside.
  • the known sabot requires a high manufacturing effort; it cannot be overlooked that the sabot cautiously hinder the projectile during the detachment process and can impair its trajectory accuracy.
  • both the front first and the rear second support have bores that are inclined against the tube core axis. These are intended to enable a portion of the propellant gases formed during the weft development to pass through the pipe opening and thus help the entire arrangement to a predeterminable swirl.
  • One major disadvantage cannot be overlooked here: the amount of propellant gas used to generate the swirl is lost in order to achieve the highest possible initial velocity of a projectile.
  • the invention has for its object to provide a generic drive cage, which meets the following requirements: simple manufacture, exploitation of essentially the entire amount of propellant gas to increase performance due to the greatest possible initial speed of the projectile and trouble-free detachment of the drive cage in order to achieve the most commuting-free flight of the projectile with increased To ensure target effect.
  • a first sabot 1 with a front support 2 and a rear support 3 has three segments 4, 5 and 6, which touch each other in pairs in butt joints 7, 8 and 9.
  • the front support 2 consists of webs 10, 11 and 12, which are separated from one another by spaces 13.1, 13.2 and 13.3.
  • the webs 10, 11 and 12 are each delimited on the front by a curved surface 14 and on the rear by a curved surface 15 and inclined in the direction of an arrow S indicating the direction of the weft against a central longitudinal axis 20 and have a narrow front end surface 16 and an outside support surface 29 on.
  • a circular cylindrical central receptacle 18 for a balancing projectile extends along the longitudinal axis 20 from a rear edge 17 to a front edge 28 of the sabot 1.
  • the receptacle 18 has form-locking means 19 on the circumference for corresponding form-locking means on the balancing projectile.
  • the rear support 3 surrounds the longitudinal axis 20 with a closed circular cylindrical peripheral surface 30 and has a receptacle 32 in the peripheral region for a sealing tape (not shown).
  • the rear support 3 is formed on the front as an air pocket delimited by an edge 35 with a base area 36 and is delimited on the back by a gas pressure receiving area 31 which has a respective groove 34 in the area of the butt joints 7, 8 and 9 for receiving a sealing element (not shown).
  • the sabot 1 surrounds the balancing projectile in a form-fitting manner, the mouth of a weapon barrel in the direction of arrow S, the incoming air can pass through the spaces 13.1, 13.2 and 13.3 into the air pocket 33 and thus initiates the detaching process of the segments 4, 5 and 6 from the balancing projectile .
  • a lever arm 37 extending from the rear edge 17 (as a rolling edge opposite the balancing projectile) to the base surface 36 of the air pocket 33 is comparatively short and the detachment process of the segments 4, 5 and 6 due to the large distance from the missile tip is not affected by the pressure fluctuations in the front area. From the comparatively Small mass of the respective segment 4, 5 and 6 also results in a significantly reduced impact on the balancing projectile, which is thereby advantageously excited to oscillate considerably less.
  • the webs In a second sabot according to FIG. 3, the webs, of which only one web 40 is shown, are bounded on the front by a comparatively wider surface 42, which consequently offers greater resistance to the incoming air.
  • the webs are made of low density plastic.
  • a main part of a light metal alloy not designated in any more detail, has an outer surface 23 formed from paragraphs 23.1 to 23.5 with dovetail grooves 25.1 and 25.2.
  • the web 40 is made of plastic and is inserted into the dovetail grooves 24.1 and 24.2.
  • a region with the weakest cross section is designed as a predetermined breaking point 25.
  • the webs 40 When leaving the gun barrel, the webs 40 are flown by the air in the area of the surface 42 and break off at 25.
  • the further detaching process takes place essentially as described in connection with the first embodiment. Due to a design of the gas pressure receiving surface on the sabot not shown, the segments can be detached from the balancing projectile starting from the back or also essentially parallel to the longitudinal axis of the projectile.
