This report describes the development of a laboratory working model of a solid chemical oxygen generating system. A design study was conducted to aid in designing a system which would satisfy program specifications and provide operational flexibility and simplicity, minimal maintenance and safe operation. The system which evolved featured remote and local control of the system, automatic and manual operation modes, six sodium chlorate candles contained in individual rechargable generators and delivered oxygen compatible with MIL-STD-E-83252 USAF. Each of the sodium chlorate candles were 1.75 in. dia. by 11.75 in. long and contained 6 Fe fuel. The six generators contained in integral filter for contaminant removal. A regenerable dryer using molecular sieves Linde 13X was provided for moisture control. For each of the six generators a mass flowmeter was supplied for monitoring the oxygen generation rate. The generated oxygen was stored in a 500 cu. in. accumulator at less than 500 psig. An ignition control system using 28V DC power was developed which permitted the generator activation sequence to be programmed for automatic operation. An override was included for manual operation. Also, an automatic safety override was designed into the ignition control system which removed generator activation power and indicated when the system pressure exceeded 400 psig.
