Low temperature gas generator propellant
TLDR
In this article, a pyrotechnic composition is adapted, upon combustion, for generating a low-flame temperature, non-toxic gas for inflating a vehicle safety bag or other inflatable device.Abstract:
This pyrotechnic composition is adapted, upon combustion, for generating a low-flame temperature, non-toxic gas for inflating a vehicle safety bag or other inflatable device. The composition comprises: a fuel, such as a carbonaceous material, aluminum or magnesium; an inorganic oxidizer, such as a metal chlorate, a metal perchlorate, a metal nitrate, ammonium chlorate, ammonium perchlorate or ammonium nitrate; and a coolant or combined binder and coolant, such as magnesium carbonate, magnesium hydroxide or a mixture of magnesium hydroxide and magnesium carbonate. A typical example of this composition comprises: carbon as the fuel; potassium chlorate as the oxidizer; and magnesium carbonate or a mixture of magnesium hydroxide and magnesium carbonate as the binder-coolant. One may use as much of this later mentioned binder-coolant as is necessary to obtain the desired binding properties in the composition, without raising the flame temperature of the gas to an unacceptable level.read more

Gas-generating apparatus
TL;DR: In this paper, electrical ignition devices ignited the propellant in two pockets first to release gas for deploying or partially expanding the folded inflatable bag, and filled channels connected the two initially ignited propellant pockets to the remaining pockets for igniting the latter, releasing gas for inflating the bag to a desired pressure.
