Chemical generator is developed for producing O [2] ([1] ?) at high pressure. Such generators are especially important for supersonic chemical oxygen-iodine lasers. The model treats different types of generators, e.g., bubble-column, film, aerosol, and jet generators. A chemical oxygen generator is a device that releases oxygen created by a chemical reaction. The oxygen source is usually an inorganic superoxide, chlorate or perchlorate. A promising group of oxygen sources are ozonides. The generators are usually ignited mechanically, by a firing pin. The chemical reaction is usually exothermic, making the generator a potential fire hazard.
