Definitions

  • Rockets for projectiles comprising a body in which is disposed a primer-carrier rotor with two primers, of different characteristics, capable of cooperating with a detonator, a striker carried by a cap covering said body, this striker being moved axially upon impact of the projectile to strike a primer.
  • a rocket of this kind is described in particular in French patent N ° 1 20- + -1-50.
  • the primers are arranged in a median plane of the rocket, but are angularly offset on the rotor. The latter must therefore perform a different rotation to bring one or the other of the primers in the active position, which leads to a relatively complicated and expensive construction.
  • the invention aims to obtain the same operating advantages with a simpler construction and therefore more reliable and less expensive.
  • the rocket which is the subject of the invention is characterized in that the two primers are mounted side by side on the rotor, means being provided to allow the striker to cooperate at will with one or the other. 'Another of said primers, the rotor always performing the same angular displacement to bring the primers in the active position.
  • Figure 1 is an axial section of this rocket.
  • Figure 2 is a section along line II-II of Figure 1.
  • Figure 3 is a partial section along line III-III of Figure 1.
  • Figure - * is a section along line IV-IV of Figure 1.
  • the rocket comprises a body 1 on which a cap 2 is mounted which can be moved angularly relative to the body 1.
  • the position given to the cap 2 is preserved thanks to the friction exerted on the body 1 by a ring 3 forming a cam, integral with the cap and provided with two annular seals and 5.
  • the front part of the cap 2 carries a striker 6 pushed against a cap 7 by a spring 8.
  • This striker is provided with a point 9 which is eccentric relative to the longitudinal axis of the rocket.
  • This striker is intended to cooperate with one or the other of two primers 10 and 1 1 which are carried by a rotor 12, the latter being shown in Figure 1 in the safety position, position in which the two primers are arranged outside the trajectory of the tip 9 of the striker 8.
  • This rotor 12 is integral with a shaft 13 pivoting in bearings I -. carried by the body 1. The ends of this shaft 13 each have a flat 15 located opposite a projection 16 of the ring 3 when the latter is in the safety position given by the angular position of the cap 2.
  • This device comprises an inertia lever 17 pivotally mounted on one of the bearings 1 *.
  • This inertia lever has its center of gravity eccentric relative to the axis of the shaft 13 and it is retained in the position of safety, illustrated in FIGS. 3 and -, by a lock 18 engaged in a notch 19 of this lever, as well as in another notch 20 of the rotor 12, this lock being biased by a spring 21 towards the outside of the projectile, maize is retained in position by one of the projections 16 of the ring 3, when the latter is in the safety position.
  • the lever 17 is subjected to the action of a pusher 22, subjected to the action of a spring 23, applying it against a bearing part 2 of the lever 17.
  • a torsion spring 25, wound on the shaft 13 of the rotor 12, is fixed by one of its ends to the lever 17 and by its other end to the shaft 13.
  • This spring 25 is intended to supply the engine torque to rotate the rotor 12 after the start of the blow and bring it into the active position allowing the tip 9 of the striker to strike one or the other of the primers 10 and 11.
  • the rotation of the rotor 12 is tempo ⁇ sée by means of a mechanism exhaust 26 which is of conventional construction.
  • this mechanism comprises a multiplier gear train 27 co ⁇ operating with a balance 28.
  • the mechanism is attacked by a toothed sector 29 integral with the rotor 12 and meshing with a toothed pinion 30 dudi t mechanism.
  • the two primers 10 and 1 1 are intended for firing a reinforcing relay 31, which, in the armed position of the rocket, is arranged opposite a pyrotechnic transmission relay 32 ( Figure 1) intended for the ignition of a detonator or booster 33.
  • the two primers 10 and 1 1 have different characteristics, the primer 10 being intended for instantaneous firing, while the primer 1 1 is performed to provide a delay in firing, which delay is generally only a fraction of a second after impact.
  • the operation of the rocket is as follows:
  • the cap 2 Before loading the weapon with the projectile, the cap 2 must be maneuvered to remove the transport safety by releasing the projections 16 from the flats 15, this cap being turned in one of the two positions, in order to place the point 9 of the striker 8 opposite that of primers 10 and 1 1 which corresponds to the desired operating mode.
  • this lever 17 When this lever 17 has made a rotation of about a quarter of a turn, it completely releases the lock 18 thanks to a recess 35 provided in this lever and in which the lock 18 engages to lock the lever 17 in its armed position.
  • the rotor 12 is then unlocked and turns under the effect of the engine torque exerted by the spring 25, this movement being timed by the mechanism 26.
  • the rotor has made an angular movement of approximately a quarter of a turn, the duration of this movement being provided to ensure the desired muzzle safety, one of the primers 10 or 11 is located opposite the tip 9 of the striker, while the reinforcing relay 31 is placed opposite the relay 32 and the detonator 33 .
  • the striker could have a point centered on the axis of the projectile, means being provided for bringing one or the other of the two primers opposite this point.
  • the two primers could be offset angularly on the rotor 12, a retractable stop allowing the rotor to be locked in one or the other of two operating positions.
  • the ring 3 could also rotate relative to the cap 2 and have an accessible part from the outside of the projectile to place it in the desired position.
