초록 ▼

A priming device for a projectile incorporating a safety and arming device as well as an electrically initiated detonator that is activated by an electronic firing module, wherein the priming device incorporates a second detonator integral with a rotor or flap of the safety and arming device, the second detonator being activated by a mobile firing pin, such firing pin being arranged opposite a first detonator so as to be projected by the gases resulting from the ignition of the latter.

대표청구항 ▼

1. A priming device for a projectile comprising: a body;a safety and arming device; anda first electrically initiated detonator that is activated by an electronic firing module, whereinthe priming device incorporates a second detonator integral with a rotor or flap of the safety and arming device,the second detonator is activated by a firing pin,the firing pin is arranged in a fixed position relative to the body and arranged opposite the first detonator of the priming device,the firing pin is integral with a spacer plate fixed with respect to the body of the projectile, the spacer plate incorporating an embrittlement groove surrounding the firing pin, andthe firing pin is configured to be detached from the fixed position by shearing of the spacer plate through a thickness of the spacer plate within the embrittlement groove upon ignition of the first detonator and to be projected by the gases resulting from the ignition of the first detonator. 2. The priming device according to claim 1, wherein the embrittlement groove delimits a cup integral with the firing pin, the cup delimiting a cavity in which the first detonator is positioned. 3. The priming device according to claim 2, wherein the first detonator and the firing pin are arranged along a lengthwise axis of the projectile. 4. The priming device according to claim 1, wherein the embrittlement groove delimits a small median plate incorporating a face lying opposite the first detonator. 5. The priming device according to claim 4, wherein the priming device incorporates a washer integral with the body of the projectile, the washer against which the plate is pressed and which incorporates a median part against which the face of the median plate is pressed. 6. The priming device according to claim 5, wherein the washer incorporates drill holes to enable a plastic coating material for the electronic firing module to be cast. 7. The priming device according to claim 6, wherein the drill holes are made in a circular groove in the washer, the groove intended to receive part of the plastic coating material. 8. The priming device according to claim 7, wherein the first detonator and the firing pin are arranged along a lengthwise axis of the projectile. 9. The priming device according to claim 1, wherein the first detonator and the firing pin are arranged along a lengthwise axis of the projectile. 10. The priming device according to claim 9, wherein the first detonator is connected to an electronic card of the firing module. 11. The priming device according to claim 10, wherein the electronic card carries a cap at least partially surrounding the first detonator, the cap ensuring an electrical contact between the card and the first detonator. 12. The priming device according to claim 1, wherein the firing pin maintains the fixed position before and after firing of the projectile. 13. The priming device according to claim 1, wherein the firing pin maintains the fixed position before and after arming of the projectile.
