Abstract
A system for initiating shock tube which has a low cost of manufacture, is relatively impervious to moisture, and initiates the shock tube reliably is described. The initiating system comprises a thermal input initiator device, a thermal enhancing output device, and a length of shock tube. The thermal input initiator device converts the thermal flame energy to percussive energy that travels as a signal wave along the shock tube at a speed of 6500 ft/sec. The signal wave hits the thermal enhancing output device and is converted back into thermal energy that is capable of reliably initiating display fireworks.
Claims22
An apparatus comprising:
- a input initiator device wherein an amount of a chemical composition is enclosed therein, said chemical composition having the characteristics of a BCTK composition which provides a deflagrating, percussive shock explosion upon ignition;
- an output device, wherein an amount of said chemical composition is enclosed therein;
- and
- a length of high velocity shock tube wherein the input initiator device is operably coupled to a first end of the length of shock tube and the output device is operably coupled to a second end of the length of shock tube.
An apparatus comprising:
- a length of high velocity shock tube;
- and
- a output device operably coupled to the length of high velocity shock tube, wherein an amount of a chemical composition is enclosed within said output device, said chemical composition having the characteristics of a BCTK composition which provides a deflagrating percussive shock explosion upon ignition.
