| Abstract: |
A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner. The external geometry of the projectile also is configured so that the projectile tumbles when launched and follows a more predictable, repeatable and accurate path in flight.

First Claim:
Show all 20 claims |
We claim:
1. A fireworks projectile for exploding into an aerial fireworks display, comprising:
- (a) an explosive charge adapted for connection to a detonating fuse, wherein the charge contains a composition adapted to explode into a fireworks display upon ignition by the fuse; and
- (b) a shell containing the explosive charge, wherein the shell has a substantially smooth, uninterrupted external surface geometry comprising a substantially cylindrical body having semi-spherical opposing end portions, the external surface of the shell comprising:
- i) a recess adapted to receive the fuse underneath the external surface of the shell; and
- ii) a cover for covering the recess and substantially maintaining the continuity of the external surface geometry of the shell.
