Benefits of technology

The patent describes a non-lethal payload that includes an illuminant and an igniter. The illuminant is made of fuel, oxidizer, and boron or silicon. The igniter is made of fuel and oxidizer. A method of making the non-lethal payload without using a solvent is also provided. The technical effect of this invention is to provide a safe and effective way to create a non-lethal payload that can be used in various applications such as training and defense.

Problems solved by technology

The level of light and sound output is designed to temporarily incapacitate people within the proximity of the activated device with a calculated risk of permanent injuries depending on the given stage in the escalation of force.
The flash of light (e.g., a fireball) may temporarily blind a person viewing the fireball, and the sound or pressure impulse produced by the device may incapacitate a person's auditory capabilities.
It has been determined that while these non-lethal payloads are effective, a non-lethal payload including only a powdered metal as the illuminant was not efficient because either the non-lethal payload was not totally dispersed upon initiation, or the reaction of the powdered metal was quenched before complete combustion occurred.
Processing of a granular igniter / activator is time and labor intensive due first to the labor intensive slurry mixing, wet granulation, drying, and dry granulation process described above.

example 1

Cylindrical Test Vehicle Performance

[0046]Formulations A-C were tested in a cylindrical test vehicle in which the igniter was placed in a central flash tube fabricated with sixteen outlet holds. The outer diameter of the flash tube was sealed with a wrapping of aluminum tape to block the holes in the flash tube and prevent leakage of the igniter into an annulus of the flash tube. The illuminant was loaded into the annulus between the flash tube and an outer body of the test vehicle. An electric match was inserted into the flash tube through the top of the test vehicle to activate the test vehicle. Cameras and test gauges were set up surrounding the test vehicle according to measure the flash intensity and the magnitude of the pressure impulse upon activation of the test vehicle. The cameras and test gauges used to measure the flash intensity and pressure impulse were set up according to conventional techniques.

[0047]The flash intensity and pressure impulse of Formulations A-C were d...

Shotshell Test Vehicle Performance

[0049]The pressure and light output for non-lethal payload formulations was tested in 12-gauge shotshells as the test vehicle. The formulations included Formulation B as described above. For comparison, a formulation including a granular mix (70:30) of Mg / Sr(NO3)2 (available from Alliant Techsystems Inc. as UIX 191) and B / KNO3 (available from Alliant Techsystems Inc. as UIX 156) as the igniter, and 59.3 wt % magnesium, 32.7 wt % B / KNO3 (available from Alliant Techsystems Inc. as UIX 156), and 8 wt % Mg / Sr(NO3)2 (available from Alliant Techsystems Inc. as UIX 191) was prepared and is designated below as Formulation D. An additional formulation lacking boron in the illuminant was also produced and is designated below as Formulation E. Formulation E included 13.4 wt % KNO3, 76.6 wt % magnesium, and 10 wt % Sr(NO3)2 as the illuminant, and 21 wt % KNO3, 38 wt % magnesium, 33 wt % Sr(NO3)2, and 8 wt % B as the igniter. Formulation E differed from Formulat...
