Definitions
- the invention relates to a safety device for detonators of warheads according to the preamble of claim 1.
- Such safety devices are intended to unlock the detonators depending perform certain criteria automatically or in the case of a Malfunction will cause the fuse to jam in the fuse.
- each detonator comprise at least two securing elements must, independently of each other, the accidental fuse of the detonator and thus prevent the main charge from igniting.
- Each must these securing elements from at least one not through to the other Element acting environmental force can be operated.
- the invention has for its object a safety device for detonators to create warheads that only exist in the correct two Sequence occurring and independent of each other physical Unlocked criteria and guaranteed complete reliability of the igniter.
- the detonator on the ignition rotor by eliminating the detonator on the ignition rotor and by the two detonators assigned to the control rotor ensure the functional reliability given the ignition device.
- a possible incorrect setting of the Ignition rotor is not a safety-critical case. This also contributes to the transfer charge of the ignition rotor consists of a secondary explosive.
- the security requirements are met by the measures according to the invention according to MIL-STD-1316 and according to STANAG 4187.
- One occurs at the detonator direct locking of the control rotor via a mechanical connection between a magnet and the control rotor by an additional one Locking pin. Because of these measures, the control rotor secured by the recoil mass, its unlocking by the launch acceleration done, and secured by the locking pin to the magnet, its unlocking is done by the electrical signal of the missile launch.
- the securing device for an igniter of a warhead for missiles, Missiles or the like starts from two rotors, one of which is the first rotor a control rotor 1 and the second rotor is an ignition rotor 2, both by an external toothing are in gear connection with each other.
- the drive of the control rotor 1 takes place in principle by the launch acceleration of the Missile.
- the rotational movement and the direction of rotation of the control rotor 1 determined by a radially outward center of gravity.
- the ignition rotor 2 has a radially outward center of gravity, which makes it easy to carry is facilitated by the control rotor 1 via the toothing 3.
- a two-armed lever 5 acts on an electromagnetic locking device 4, which is pivotable about the axis 6. At the free end of the lever 5 is in the middle Area connected a locking pin 7 for a recoil mass. On additional locking pin 8 is with the outer end of the second lever arm connected and engages in the control rotor 1.
- This Design means a direct locking of the control rotor 1 by the additionally attached to the lever 5 locking pin with the electromagnetic Locking device 4. In this way, the control rotor 1 is once through Backfire mass secured. The control rotor 1 is unlocked by Accelerated launch of the warhead with the missile.
- the second fuse forms the additional locking pin 8 in connection with the electromagnetic Locking device 4, the unlocking by the electrical signal of the rocket launch.
- control rotor 1 and the ignition rotor 2 are in section in one Warhead 9 shown.
- the two rotors 1 and 2 are by external teeth 3 back in gearbox connection.
- Located in the two rotors 1 and 2 transfer charges 10 and 11.
- There are two around the control rotor 1 180 ° opposing detonators 12 and 13 are provided, which are in corresponding Channels or recesses 14 and 15 of the warhead 9 are located.
- the channels 14 and 15 and with them the detonators 12 and 13 are thereby coaxial aligned with the axis of rotation of the control rotor 1.
- FIG. 3 is made up of the three superimposed representations of the Rotors together.
- the top illustration in FIG. 3 shows the securing position, the middle representation reveals the transition position and the lower representation shows the unlocked ignition position.
- both rotors are equipped with centers of gravity from the center are offset radially outwards from or from the axis of rotation. For example, this will reached through the recesses 16 and 17 in the rotors.
- the detonators 12 and 13 can be seen, each in this example are assigned to one of the rotors. Detonators 12 and 13 are in Holes of a security base plate. Furthermore, in the control rotor 1 and Ignition rotor 2, the ignition transformer 11 and 10 shown.
- a first locking pin 7 engages in the control rotor 1, while the second locking pin 8 in the Movement path of the ignition rotor 2 is used.
- the locking pins 7 and 8 are firmly attached to a common device, for example lever 5. How 3 can be seen, the locking pin 7 with an escapement gear 18 in operative connection. Are in this securing position the transfer charges 10 and 11 of the two rotors 1 and 2 outside the positions of the detonators 12 and 13. Only by a rotary movement, caused by the acceleration of the warhead at the launch of the missile the transfer charges move according to the direction of rotation of the two rotors 1 and 2 to the positions of the detonators 12 and 13. The synchronous process is guaranteed by the double-sided toothing 3.
- the locking pin 8 remains in position via the lever 5.
- This desired mechanical locking of the ignition rotor 2 according to FIG. 3 is made possible by the fact that the recoil mass has been increased and a additional locking pin 8 has been used, which is directly mechanically in the Ignition rotor 2 engages. By this measure, the ignition rotor 2 is double mechanical locked by the recoil mass and by the interlocking with the Control rotor.
