Abstract
A pyrotechnic projectile, an electronic controller for a pyrotechnic projectile, and a method of controlling a pyrotechnic projectile are provided. The pyrotechnic projectile comprises: a burst charge, configured to provide an a visual and/or audible effect upon activation thereof; an electronic match configured to activate the burst charge; and an electronic controller, coupled to the electronic match. The electronic controller is configured to determine an altitude of the pyrotechnic projectile and cause the electronic match to activate the burst charge at least in part according to the altitude of the pyrotechnic projectile.
Claims16
A pyrotechnic projectile comprising:
- a lift charge configured to propel the pyrotechnic projectile;
- a burst charge, configured to provide a visual and/or audible effect upon activation thereof;
- a first electronic match configured to activate the lift charge:
- a second electronic match configured to activate the burst charge;
- and
- an electronic controller, coupled to the first electronic match and the second electronic match, including an altitude sensor configured to measure an altitude of the pyrotechnic projectile, wherein the controller is configured to cause the first electronic match to activate the lift charge, and wherein the controller is configured to poll the altitude sensor to determine when the altitude of the pyrotechnic projectile is above a predefined threshold altitude and cause the second electronic match to activate the burst charge at least in part according to the altitude of the pyrotechnic projectile.
A method of controlling a pyrotechnic projectile, the method comprising:
- using an electronic controller to cause a first electronic match of the pyrotechnic projectile to activate a lift charge of the pyrotechnic projectile to propel the pyrotechnic projectile;
- measuring an altitude of the pyrotechnic projectile with an altitude sensor;
- polling the altitude sensor to determine whether the altitude of the pyrotechnic projectile is above a threshold altitude;
- using the electronic controller to cause a second electronic match of the pyrotechnic projectile to activate a burst charge of the pyrotechnic projectile at least in part according to the measured altitude of the pyrotechnic projectile, causing the burst charge to provide a visual and/or audible effect upon activation thereof.
A pyrotechnic projectile comprising:
- a lift charge configured to propel the pyrotechnic projectile;
- a burst charge, configured to provide a visual and/or audible effect upon activation thereof;
- a first electronic match configured to activate the lift charge:
- a second electronic match configured to activate the burst charge;
- and
- an electronic controller, coupled to the first electronic match and the second electronic match, including an altitude sensor configured to measure an altitude of the pyrotechnic projectile wherein the controller is configured to cause the first electronic match to activate the lift charge, and wherein the controller is configured to poll the altitude sensor to determine whether the altitude of the pyrotechnic projectile is above a predefined threshold altitude and cause the second electronic match to activate the burst charge at least in part according to the altitude of the pyrotechnic projectile, and wherein the altitude sensor is a barometric pressure sensor mounted on the projectile configured to send the altitude measurements to the controller.
