Definitions

  • the invention relates to a safety device for a rotor of an igniter, in particular a rocket igniter.
  • DE-PS 26 40 782 describes a safety device on an igniter.
  • the rotor carries an ignition means. It is held securely by an axially displaceable steady bolt. This releases the rotor when the projectile is fired. A torsion spring then turns the rotor into focus.
  • the object of the invention is to propose a safety device of the type mentioned, in which the rotor is unlocked by the effect of the dynamic pressure.
  • the above object is achieved with a safety device in that an air storage space is provided in which a piston is mounted, and in that a slide engages the piston, which locks the rotor in the rest position of the piston and releases it in the shifted position of the piston.
  • a safety device in that an air storage space is provided in which a piston is mounted, and in that a slide engages the piston, which locks the rotor in the rest position of the piston and releases it in the shifted position of the piston.
  • the slide is coupled to a pivoting member which, when the slide moves, tensions a tension spring so that it pivots the rotor into the armed position.
  • An air storage space 1 is formed on a detonator. This is connected via a line 2 to an opening, not shown, at the head of the rocket.
  • the dynamic pressure acting on the head when the rocket is launched acts via line 2 in the air storage space 1.
  • the direction of launch is represented by the arrow P.
  • a piston 3 is mounted in the air storage space 1. This can be moved transversely to the firing direction P.
  • the piston 3 has a guide cone 4 which ends in a cylindrical section 5.
  • the cylindrical section 5 engages in a circular opening 6 of a slide 7.
  • the slide 7 is held on the piston 3 by means of a screw head 8. In the position shown in FIG. 1, the screw head 8 lies in a recess 9 in the slide 7. As a result, the slide 7 is secured against displacement in the event of impacts occurring during environmental tests.
  • the piston 3 has a groove 10 into which a pin 12 loaded with a spring 11 engages.
  • the bolt 12 secures the piston 3 against displacement when 3 impacts are exerted during environmental tests in the displacement direction of the piston.
  • the slider 7 engages with an extension 13 in a recess 14 of a rotor 15. This is thereby secured against rotation about its axis A.
  • An inclined surface 16 is formed on the extension 13 (cf. FIG. 2). This is assigned a lever 17.
  • the lever 17 is rotatably supported at its end 18 (see FIG. 3). With a pin 19 provided at its other end, the lever 17 engages in a slot 20 of a segment-shaped pivot member 21. Between the end 18 and the pin 19, the lever 17 rests on the extension 13 with a nose 22.
  • a drive member 24 rotatable on the rotor axis A engages in a toothing 23 of the swivel member 21.
  • the bolt 12 is released from the groove 10 during the launch acceleration.
  • the dynamic pressure occurring at the tip of the missile displaces the piston 3 in the direction of the arrow K (see Figure 1).
  • the screw head 8 moves out of the recess 9 and the guide cone 4 moves the slide 7, so that its extension 13 moves out of the recess 14.
  • the rotor 15 is thus free, but does not turn into the focus.
