- the invention also relates to a process for the said action advice .
- An action device for graduated explosive effect is normally designed with a plurality of action parts comprising one or more explosive charges, the action parts being mutually separated with barriers to prevent flashover between the action parts.
- the action parts can be activated simultaneously or in sequence with various time delays.
- the action parts can also comprise an additional material for the achievement of special effects, such as: fire, lighting or smoke effect.
- US 4 658 727 discloses an action device comprising a plurality of action parts, in which each action part comprises an explosive charge and at least one detonator.
- the action parts are mutually separated with barriers to prevent flashover.
- the detonators are coupled to an activation unit for activating one or more action parts with regard to a desired grade of effect.
- each action part comprises two detonators arranged such that the direction of action can be influenced.
- activation implies an explosive effect at right angles to the longitudinal axis of the action device.
- a time delay implies a deflection of the explosive effect in the one or other direction.
- Action devices according to US 4 658 727 having a plurality of detonators connecting to the explosive charges of the action parts, imply an increased risk of accidental initiation.
- a plurality of detonators for controlling the grade of effect imply, moreover, a relatively complex system.
- a main object of the present invention has been to provide an improved action device for graduated explosive effect, especially intended to form part of a shell for firing from a gun barrel, in which the risk of accidental initiation has been eliminated or severely reduced.
- a further object of the present invention has been a process for the said action device.
- an improved action device for graduated explosive effect has been provided, especially intended to form part of a shell for firing from a gun barrel, in which the risk of accidental initiation has been eliminated or severely reduced.
- the action device comprises at least two action parts comprising a fuel and an oxidizer, and an activation device for activating the action parts, which activation device comprises a detonator.
- Characteristic thereof is that the fuel and the oxidizer are separated up to activation and that the detonator and the action parts are designed for the initiation of one or more action parts, depending on the grade of explosive effect which is to be obtained.
- the oxidizer is arranged in oxidizer containers and the fuel is arranged in fuel containers, which oxidizer containers are tubular and are arranged between the activation device and the fuel containers, the oxidizer containers comprising radially arranged oxidizer outlets connecting to the fuel containers, and the oxidizer outlets being sealed with openable oxidizer seals,
- the oxidizer seals comprise plastics foils arranged on the inner side of the oxidizer containers,
- the activation device comprises a pressure container, which pressure container contains pressurized gas, and in the pressure container there are arranged gas outlets connecting to the oxidizer containers, which gas outlets are sealed with openable seals,

- Fig. 3 shows a part-enlargement of an oxidizer container according to the action device in Figure 1.
- Fig. 1 a first embodiment of an action device 1 designed for graduated explosive effect.
- graduated explosive effect is here meant an explosive effect which can be gradually altered, in a number of steps, from low to medium-high explosive effect and from medium-high to high explosive effect, depending on how many action parts 4, 5, 6 are activated. The number of steps depends on how many action parts are included in the action device.
- the action device 1 is contained in a shell body 2 between the front part of the shell body 2, also referred to as the nose part, and the rear part of the shell body 2.
- the action device 1 comprises three action parts 4, 5, 6, axially arranged one behind the other in the longitudinal axis A of the shell body 2, the front action part 4 of the action device being arranged closest to the nose part of the shell body, followed by the intermediate action part 5 of the action device 1 and a rear action part 6 thereof.

- the pressure container 18 is pressurized with a gas 19, preferably an inert gas, for example helium, nitrogen or argon.
- the activation unit 3 further comprises three gas outlets 20, to which the three oxidizer containers 11, 12, 13 are connected.
- the gas outlets 20 are, initially, closed off with openable seals 21 to prevent the pressurized gas 19 from streaming out into the oxidizer containers 11, 12, 13 prior to activation.
- the seals 21 are constituted, preferably, by rupture plates 21.
- opening devices 22 for opening the seals 21 in response to an activation signal from a control unit 24, referred to as a CPU (Control Process Unit) 24.

- the opening devices 22 can comprise pyrotechnic charges 22 fitted on the seals 21.
- opening devices 22 can possibly be used, for example electromagnetic devices in which plungers or needles (not shown) are activated to puncture the seals 21.
- the opening devices 22 are electrically activated via the CPU unit 24 in the nose part of the shell body 2, either by a preset activation program or by a signal from an active target-seeking sensor 25.
- the oxidizer containers 11, 12, 13 are axially arranged in the shell body 2 between the activation unit 3 and the fuel containers 7, 8, 9.
- the front oxidizer container 11 runs from the activation unit 3 through the front fuel container 7 up to the front barrier 15.
- the intermediate oxidizer container 12 runs from the activation unit 3 parallel with the front oxidizer container 11, through the front fuel container 7 and onward through the intermediate fuel container 8, up to the intermediate oxidizer barrier 12.
- the rear oxidizer tank 13 runs from the activation unit 3 parallel with the front 11 and the intermediate oxidizer container 12 up to the rear oxidizer barrier 16. That part of the oxidizer containers 11, 12, 13 which is located in the respective fuel container 7, 8, 9 comprises radially arranged oxidizer outlets 26.
- the oxidizer outlets 26 are, initially, sealed with gas-tight openable oxidizer seals 27.
- the openable oxidizer seals 27 are constituted, preferably, by plastics or metal foil arranged on the inner side of the oxidizer containers 11, 12, 13.
- the oxidizer seals 27 are constituted by rupture plates 27 arranged either on the outer side or on the inner side of the oxidizer outlets 26.
- the oxidizer seals 27 are openable in response to a specific pressure increase in the oxidizer containers
- the oxidizer containers 11, 12, 13 consist, preferably, of stainless steel in order to cope with the storage of corrosive gas, but can also consist of corrosion- resistant plastic.
- the oxidizer 14 is gaseous or liquid and comprises oxygen gas, nitrous oxide, nitric acid or hydrogen peroxide, or mixtures thereof.
- the oxidizer 14 can be constituted by dinitramide salt dissolved in a suitable solvent, for example dimethyl formamide or tetrahydrofuran, or mixtures thereof.
- the fuel 10 is preferably constituted by a cohesive porous fuel structure 10, consisting of silicon, carbon, vanadium, beryllium, magnesium, iron, or mixtures thereof.
- the highly porous fuel 10 is configured for the quickest possible absorption of a gaseous or liquid oxidizer 14 by the fuel 10 being arranged in the form of thin porous discs at a certain distance apart in the fuel containers 7, 8, 9.
- the porous fuel 10 has a porosity, preferably, within the range 60 to 95% by volume.
- the fuel 10 can comprise a fine-grained, compacted powder 10 comprising silicon, carbon or vanadium, beryllium, magnesium, iron, or mixtures thereof.
- the powder mixture 10 has a porosity and structure which, upon contact with a gaseous or liquid oxidizer 14, in the course of initiation, can be made to detonate.
- the cohesive porous fuel structure 10 is coated with an additive to facilitate the initiation of the fuel/oxidizer mixture.
- the additive can advantageously consist of a fine-grained zirconium powder, evenly distributed in the pore structure of the fuel 10.
- the additive can also be mixed with a primer, for example picric acid.
- the pore structure of the fuel 10 is coated with a pyrophorous substance, which, upon contact with the oxidizer 14, leads to spontaneous ignition, which spontaneous ignition initiates the fuel-oxidizer mixture. The advantage is that no further initiation via a detonator is required.
- the oxidizer 14 is stored together with the pressurized gas 19 in the pressure containers 18.
- the oxidizer containers 11, 12, 13 for the storage of oxidizer 14 thus become superfluous.
- the function of the oxidizer containers 11, 12, 13 is instead to act as transport ducts for transporting the oxidizer 14 up to the fuel containers 7, 8, 9.
- the oxidizer containers 11, 12, 13 can hence be simplified by being made thinner and narrower.
- the front action part 4 is initiated.
- the front action part 4 in turn initiates the intermediate action part 5, and the intermediate action part 5 initiates the rear action part 6, subject to these having been activated. Initiation of the action part 5 takes place after a specific time delay from activation having been realized.
- the time delay can be pre-programmed via a time relay or via a pyrotechnic delay unit. Alternatively, the time delay can be determined by a target-seeking sensor during the flight of the shell towards a target.
- the target-seeking sensor can be of the radar or laser type. Alternatively, the time delay can be determined from a ground control via radar or IR link.
- the speed with which the oxidizer 14 is distributed in the pore structure of the fuel 10 is determined primarily by the gas pressure in the pressure container 18 and by the physical properties, e.g. porosity, of the fuel 10, but also by the rotational velocity of the shell body 2. High rotational velocity signifies higher mixing speed, whereas low rotation velocity signifies a lower mixing speed.
- the action device 1 is especially intended to form part of shells for firing from a gun barrel, the grade of explosive effect from the action device 1 being pre-programmed or being determined during travel of the shell towards a target.
- the action device 1 can be incorporated in robots, missiles or various types of mines.
- the action device 1 can also be incorporated in explosive devices for civil use, for example in mining or in road works.
