Definitions

  • the invention relates to a mist launcher, in particular for launching from throwing cups with a centrally located propellant charge, consisting of a can with a mist set therein, and an ignition set and a contact head with bridge igniter, delay set and a sleeve surrounding the contact head, preferably made of polyamide, with the can ingen Kontakh ".
  • Such throwing bodies are fired from throwing cups (launchers) which are attached to a tank or to another vehicle which should be able to change positions without being seen by the opponent.
  • a fog is generated very quickly, which takes away the opponent's view in a larger area. Since these projectiles have to develop mist during the flight in order to reliably fulfill the camouflage purposes, such muffler bodies are also referred to as rapid mist launchers.
  • These smoke projectors usually consist of a contact head with contact rings for the ignition of a propellant charge, with the aid of which the projectiles are expelled from the throwing cups.
  • a smoke throwing body has become known from DE-OS 29 08 116.
  • the propellant charge is enclosed in a room that is located in a contact head made of plastic.
  • Black powder is conventionally used, as is the case with other known smoke projectors.
  • black powder does not burn without residue, so that the throwing cups must be cleaned constantly in order to avoid corrosion of the walls of the cups by these residues. Corrosion would render the cups unusable.
  • Propellant charges that burn completely without leaving residues e.g. Nitroglycerin or nitrocellulose cannot be used as a powder or in block form in such throwing bodies, since on the one hand a gas pressure of about 13.5 bar within 2 milliseconds must not be exceeded in the throwing cups and on the other hand the throwing bodies at the extremely high, about 10th -fold pressures would be destroyed. In addition, such rupture discs do not reduce the expulsion pressure; After its destruction, when the thrust is inserted, this acts in full on the throwing cup base, which is usually held with a spring ring.
  • the invention is therefore based on the object to improve smoke throwing bodies of the type mentioned in such a way that materials which burn completely without residue, such as nitrocellulose and nitroglycerin, as powder or in block form, can be used as propellants while maintaining the required maximum firing pressure.
  • the contact heads are usually made of aluminum for weight and manufacturing reasons. However, this is unable to withstand the high explosion pressures of the propellants to be used according to the invention with acceptable wall thicknesses. Only by using the insert made of high-strength material, e.g. made of steel, it is possible to use nitrocellulose or nitroglycerin powder or blocks for the propellant charge.
  • the contact head is preferably made of aluminum or steel and the insert is made of high-strength steel, the insert being firmly connected to the contact head, e.g. screwed or pressed in excess.
  • the contact head and the insert are preferably made in one piece and then made of high-strength steel. It would be advantageous to arrange the deceleration set in the contact head by means of a base plate and to connect it to the propellant charge.
  • the contact head is annular.
  • the insert passes through the contact head, the insert being screwed to a cover or threaded part, the cover or the threaded part carrying the deceleration set.
  • the insert can have a first cup-shaped part which is fastened in the contact head and a second threaded part which is fastened within the first part which carries a thread and is connected to the deceleration set.
  • the delay set is preferably connected to the propellant charge via a bore, advantageously the delay set is arranged in the second threaded part.
  • the contact head is ring-shaped and the insert is screwed through the ring, the result is a particularly simple construction, which also reduces the risk of propellant particles entering threads and the risk of the propellant igniting during screwing.
  • the delay set and the ignition set can preferably be accommodated together, forming a unit, in a bore in a housing element designed as a threaded piece, the bore having a narrowed through opening.
  • the deceleration set is located on the side of the hole facing the propellant charge. This has the advantage that an immediate and direct continuation of the ignition from the deceleration set to the ignition set with an excessively rapid ignition of the fog set is avoided.
  • the housing piece for receiving the deceleration and ignition charge is preferably the second threaded part of the insert.
  • the part which closes the bowl-shaped or cup-shaped threaded part of the insert also becomes the carrier of the deceleration and ignition charge.
  • the delay set is preferably connected directly to the space for receiving the propellant set. This leads to an improved ignition of the delay set.
  • An advantageous embodiment of the invention consists in that the nozzles from which the propellant gases flow out are cast with a synthetic resin, preferably with epoxy resin. This ensures that the pressures in the interior of the room that receives the propellant initially reach a certain value and only flow out of the room after the epoxy resin has burned through
  • An advantageous embodiment consists in that the nozzles are additionally covered with a plate, preferably made of silicone rubber. This protects the epoxy resin from mechanical destruction.
  • At least three outwardly directed nozzles are preferably provided, which have a diameter of approximately 2 mm and / or a cross section of 2 mm 2 , the gas space being able to comprise approximately 1.5 to 2 cm 3 .
  • the nozzles are arranged on a circle which is larger than the diameter of the spacer mandrel arranged on the base of the throwing cup.
  • the nozzles for generating a gas cone are preferably arranged in an inclined manner, wherein in a further embodiment the nozzle axes can also run at an angle to the axis of the smoke throwing body for generating a swirl. If a smaller number of nozzles is provided, asymmetrical movements of the smoke throwing body can occur, as a result of which its flight stability is negatively influenced.
  • the nozzle axes for generating a swirl should not run through the axis of the throwing body, since it is then possible to impart a swirl to the fog throwing body, which significantly increases flight stability.
  • the pressure in the throwing cup is reduced to the desired values and, on the other hand, the propellant pressure is reduced with a delay, so that the smoke throwing body is driven out - as if with a rocket motor - which can lead to more stable behavior and longer ranges. It is also possible to influence the rate at which the deceleration charge burns up by adjusting the amount of propellant charge. Under the extremely high pressure of the propellant charge which burns without residue, the burn-up of the (predetermined) retardation charge is also accelerated, so that the ignition of the smoke set is now on can be brought forward immediately after leaving the throwing cup or to an adjustable distance behind it, only the charge quantity of the propellant charge having to be adjusted.
  • the delay includes a backup system that prevents the delay set from being blown out. Without this safeguard, the deceleration is blown out by the high pressure that arises in the high-pressure section and the blowing process ignites the fog set directly (without delay) and already mists in the throwing cup. This fog process, which begins in the throw cup, contaminates the throw cup.
  • the delay set and the ignition set for the mist set are accommodated in one housing part, the two being separated from one another only by an intermediate wall with a bore.
  • the propellant charge preferably consists of nitrocellulose or nitroglycerin powder as basic components with a binder with degressive burn-off, it being extruded or pressed.
  • a particularly preferred embodiment of the invention is that the insert is followed by a nozzle ring, which is spaced apart from it by an edge-side seal and through which the delay set penetrates, and that the can ends at the seal in such a way that it protrudes at a short distance such that when the mist set burns down the hot mist flows out through the nozzle openings of the nozzle ring, destroying the seal between the contact head and the socket, optionally through an annular space arranged in the contact head.
  • smoke projectors produce fog in two ways: First, the can can be dismantled, after which the fog either spreads in the air in a spherical manner, or dome-shaped when lying on the ground, or else in that the Mist is ejected from the ends of the throwing bodies, which creates an approximately cylindrical mist pattern.
  • the roller shape has the disadvantage of having relatively small diameters in flight. Furthermore, the flight distance is limited by the amount of the propellant.
  • the enlargement of the diameter of the fog formation and the improvement of the throwing distances are achieved as follows: After the deceleration charge is ignited and burned off by a propellant charge, the ignition charge is activated and ultimately the smoke charge is ignited. The hot gases formed pass through the nozzle ring and hit the material of the seal. This burns and allows the fog to emerge peripherally. The high internal pressure in the can accelerates it radially, which means that significantly larger smoke wall diameters can be achieved in flight than was previously possible. Due to the fact that the edge of the socket projects slightly beyond the contact head, a deflection of the mist against the direction of flight can be achieved, as a result of which the gas pressure is given a radial and an axial vector.
  • the axial vector is so large that the mist launcher is thereby accelerated further and the mist set itself acts as a rocket motor.
  • the seal can be caused, for example, by intentionally set inhomogeneities, not to immediately burn uniformly over the entire circumference, the mist can initially only emerge from the interior at one or more places under great pressure. This leads to a deliberate wobbling movement that enlarges the wall of fog. If the smoke throwing body still has a twist, this creates a helical ejection characteristic that leads to homogeneous smoke walls of large diameter. After the impact of such a smoke missile on the ground, in contrast to conventional throwing bodies, it does not remain there, but the mist that continues to flow allows the smoke chute to roll further in the direction of the throw, which also causes the smoke wall to expand.
  • a variant of this embodiment consists in that the nozzle openings are arranged conically and coaxially in the edge region of the nozzle ring and are closed by the seal, the seal being conical with the aid of a projection of the upper edge of the socket and a touching of the lower edge of the contact head lying between them Section forms in the extension of which the nozzle openings are.
  • the axis of the nozzle openings and that of the conical sections of the seals preferably form an angle of 45 ° to the axis of the can.
  • the nozzle ring can be arranged in a collar directed into the can, with the aid of which both parts can be firmly connected to one another.
  • the collar with the nozzle ring and the socket can thus be securely attached to the contact head by simply screwing them together.
  • Another preferred embodiment is that the central axes of the nozzle openings form an angle of approximately 45 ° with the throwing body axis and, if appropriate, preferably run coaxially skewed at an angle ( ⁇ ) to the central axis of the smoke throwing body for swirl formation.
  • the nozzle openings of the nozzle ring against the fog set are closed with the aid of a foil, preferably a lead-tin foil. This material is destroyed by the burning temperatures, which releases the nozzles.
  • the propelling force of the emerging mist can advantageously be increased in that the mist set is designed as a driving mist set, with at least the first of the driving mist sets in the case of a plurality of mist sets is.
  • a particularly preferred embodiment consists in that at least the mist set that burns first has a convex or conical projecting contact surface with the correspondingly recessed second mist set.
  • the fog sets usually consist of compacts. Due to the manufacture, the height of these disc-shaped bodies is limited. However, one has to rely on stacking several compacts, which has the following disadvantage: Normally, the burning rate is not uniform over the cross-section of the compacts, because the deceleration rate prefers to ignite the mists in the middle, from where the Spreads the ignition spot. However, this leads to the fact that the subsequent compact is ignited in a punctiform manner, which happens exactly at the moment when the first compact diminishes in effect. This results in the "holes" in the fog wall which can be observed particularly clearly in flight.
  • the invention provides a quick-release smoke missile with long ranges and at the same time a significantly improved fog effect.
  • the contact head 11 which is made of aluminum, is surrounded by an insulating sheath 21 which is made of polyamide and is arranged all around on the contact rings 22 and 23.
