Definitions

  • the invention relates to a method for distributing submunitions according to the preamble of claim 1.
  • a method according to the preamble of claim 1 is known from US-A-38 17 179.
  • the submunition is a mine, which is connected to the parachute pack consisting of two shells via a connecting line.
  • the mine and the parachute pack are made from a slow flying aircraft, e.g. a helicopter, thrown out manually, with the parachute pack still connected to the aircraft with a tether.
  • both the connecting line and the tether are tightened, the shell parts of the parachute pack are separated from each other by a tear thread and are to fly away.
  • the tether which is connected to the apex of the parachute, can then pull out the parachute, after which it tears off at a soil break point and thus releases the mine with a parachute.
  • This arrangement has several disadvantages. Manual ejection is only possible from a slow flying aircraft. The two halves of the pack can only be separated when both lines have been tightened. The two pack sack trays can prevent the parachute from unfolding during the slow flight and damage it. A larger area can only be covered with mines with several approaches.
  • the invention has for its object to provide a method for distributing submunitions of the type mentioned in such a way that the parachute can be deployed without danger even during fast flight, and that there is the possibility of distributing the submunitions over a larger area in a single flight .
  • a conventional pack sack can be used as a parachute pack, which can be deployed together with the submunition body from a free-flying container or attached to an aircraft in a predeterminable time sequence. It is not necessary that there is still a tether between the parachute pack and the container or aircraft. This enables fast mechanical ejection.
  • the light parachute pack cannot detract from the parachute because of the fast flight and also because of its low soft mass.
  • the fuel set with adjustable start of the burning time for driving the cutting piston allows a differentiated cutting through of the pack sack closing lines, whereby the sub munitions can be distributed at variable distances from the container despite the simultaneous ejection of several pack sacks with submunitions.
  • a suitable submunition container can hold a large number of pack sacks with submunitions and eject them one after the other or simultaneously, so that a large area can be covered with submunitions.
  • the submunition container is located on the underside of a fast-flying aircraft or missile or has been separated before the pack sacks are ejected.
  • a parachute pack sack 1 known per se From a parachute pack sack 1 known per se according to FIG. 1, eight safety lines 2 protrude, which are connected on the one hand to a submunition body 3 only shown in FIG. 2 and on the other hand to a parachute cap 4.
  • the parachute pack sack 1 made of fabric is provided with longitudinal reinforcements 5.
  • a stuff sack fastener line 6 leaves a small opening 7 through which the safety lines 2 are connected to the folded parachute cap 4.
  • the packsack closing line 6 is guided under sewn reinforcements 8.
  • a tubular cutting device 10 known per se is attached to the pack sack closing line 6 and is provided at its other end with a ring 11, through which one of the safety lines 2a is pulled and fastened.
  • the fuel set is provided in a known manner with a device for the adjustable start of the burn time.
  • the propellant gases of the fuel assembly can move a cutting piston which, when actuated, cuts through the pack sack closing line 6, whereby the pack sack can open and the parachute can unfold.
  • FIG. 2 shows a submunition container 12 which is to be fastened with a flange 13 under an aircraft, not shown.
  • a pack sack 1 with submunition body 3 has been ejected from the container 12, the safety lines 2 having already tightened and the cutting device 10 being activated by the safety line 2a.
  • the parachute 4 can open and the pack sack 1 and the cutting device 10 fly away. Due to the sudden opening, the parachute 4 experiences a large increase in resistance, which leads accordingly to a trajectory deflection downwards.
  • the flight range or spread 15 of the submunition body 3 can be set.
  • FIG. 3 shows a missile 20 with a suspended submunition container 12 in three flight phases.
  • the crosses 21 are intended to represent the impact points of the submunitions 3. Due to the different beginning of the burning time of the fuel set for driving out the cutting piston on the cutting device 10, the shown spreading widths 15 for the crosses 21 can be achieved. As can be seen, a larger area can thus be occupied by submunitions 3.
