Abstract
The present invention relates to the military field. It discloses a contact fuse for multi-purpose aircraft ammunition, characterised in that it comprises an electromechanical arming system that is easy to manufacture and does not contain any explosive material inside of same. In addition, said fuse is characterised in that it comprises an alert system that reveals a possibly unsafe condition on the ground and in that it is structurally straightforward to manufacture.
Claims6
A percussion fuze for multipurpose aerial ammunition comprising:
- a. an outer main body comprising a housing cup, a front cover and a cap;
- b. an electromechanical arming system comprising an explosive train, an explosive train multiplier, a solenoid, a life pin, an ejection spring, a firing pin, a housing fitting, an aircraft's arming cable connected to said housing fitting that in a safe position blocks said solenoid, which, when blocked, prevents the firing pin's alignment with the explosive train, an electronic card that energizes said solenoid when it is unblocked by means of the release of said aircraft's arming cable and the release of said life pin, in order to align the firing pin with the explosive train;
- and
- c. an alert system comprising a LED placed in said housing cup that will send a signal in case the fuze is armed;
- wherein:
- said explosive train is assembled in an explosive train housing cup located on the outside of the percussion fuze;
- and
- said explosive train is threaded externally in the explosive train housing cup.
The percussion fuze for multipurpose aerial ammunition of any one of the preceding claims, wherein said percussion fuze is assembled at the top (nose) and/or back (tail or base) of the ammunition.
An arming method of a percussion fuze for multipurpose aerial ammunition comprising the steps of:
- a. releasing the aircraft's arming cable from its rack once the ammunition is released from the aircraft;
- b. releasing the ejection spring, which is compressed;
- c. releasing the life pin after the release of the ejection spring that results in the unblocking of the solenoid;
- d. energizing of the solenoid that leads to unlocking the cam;
- rotating of the cam through a torsion helical spring;
- and
- f. aligning the firing pin and the explosive train.
