Claims30
An ignitor for a pyrotechnic projectile of the sort comprising a lift charge to be ignited by an electrically operated lift charge ignition device to launch the pyrotechnic projectile, and a break charge to be ignited by an electrically operated break charge ignition device to burst the pyrotechnic projectile, said ignitor comprising:
- electronic control means adapted to be carried by the pyrotechnic projectile and for receiving an electronic fire command from an external control device and, in response thereto, (1) activating said electrically operated lift charge ignition device so as to launch the pyrotechnic projectile and the ignitor, and (2) a pre-determined time after receiving said electronic fire command, activating said electrically operated break charge ignition device so as to burst the pyrotechnic projectile.
A pyrotechnic projectile comprising:
- a lift charge to launch the pyrotechnic projectile;
- an electrically operated lift charge ignition device for activating said lift charge;
- a break charge to burst the pyrotechnic projectile;
- an electrically operated break charge ignition device for activating said break charge;
- and
- an ignitor carried by the pyrotechnic projectile and comprising electronic control means for receiving an electronic fire command from an external control device and, in response thereto, (1) activating said electrically operated lift charge ignition device so as to launch the pyrotechnic projectile, and (2) a pre-determined time after receiving said electronic fire command, activating said electrically operated break charge ignition device so as to burst the pyrotechnic projectile.
A pyrotechnic projectile system comprising:
- a pyrotechnic projectile and an external control device;
- said pyrotechnic projectile comprising:
- a lift charge to launch the pyrotechnic projectile;
- an electrically operated lift charge ignition device for activating said lift charge;
- a break charge to burst the pyrotechnic projectile;
- an electrically operated break charge ignition device for activating said break charge;
- and
- an ignitor carried by the pyrotechnic projectile and comprising electronic control means for receiving an electronic fire command from said external control device and, in response thereto, (1) activating said electrically operated lift charge ignition device so as to launch the pyrotechnic projectile, and (2) a pre-determined time after receiving said electronic fire command, activating said electrically operated break charge ignition device so as to burst the pyrotechnic projectile.
A pyrotechnic projectile system comprising:
- a plurality of pyrotechnic projectiles and an external control device;
- each of said pyrotechnic projectiles comprising:
- a lift charge to launch the pyrotechnic projectile;
- an electrically operated lift charge ignition device;
- a break charge to burst said pyrotechnic projectile;
- and
- a fuse for activating said break charge, said fuse being carried by the pyrotechnic projectile and being activated by said electrically operated lift charge ignition device;
- said external control device comprising a port, with said plurality of pyrotechnic projectiles being connected to said port, and said external control device being adapted to detect when the number of said pyrotechnic projectiles connected to said port exceed a predetermined number.
