摘要： A compact ignition system for chemical oxygen generators for possible use in an aircraft. The chemical oxygen generator is configured such that a majority of the ignition system can be accommodated within an interior of the generator body. In some embodiments, the ignition system is positioned within a recess of an upper surface of the core of the generator. Housing a majority of the ignition system within the generator allows the overall oxygen-generating capacity of the generator to be increased without requiring a corresponding increase in the overall length of the generator.

摘要： An improved chemical oxygen generator (10) includes an oxygen generating candle (12) having an oxygen source, which upon decomposition will yield oxygen, and a nontoxic additive to smooth decomposition and suppress formation of toxic free chlorine gas. The nontoxic additive may be taken from the group consisting of: (1) the oxides, hydroxides and carbonates of calcium and the rare earth elements; (2) the hydroxides and carbonates of magnesium; and (3) mixtures of the foregoing. A complete chemical oxygen generator utilizes the candle (12) of the invention. The oxygen generator preferably includes a canister (14), oxygen-generating candle (12), and an ignition device (16). Triggering of the ignition device ignites an ignition pellet (52) which initiates decomposition of the candle body (50). Once initiated, the candle will sustain decomposition to release breathable oxygen until the candle is completely reacted.
