SOLID PROPELLANT COOL GAS GENERATOR
Abstract
One of the major problems encountered in inflatable devices has been the degradative effect of high-temperature propellant gas on materials, resulting in rupture and/or burning of fabric structures. This problem has been eliminated through the use of a packed-bed chemical heat exchanger, thereby reducing effluent gas temperature to an acceptable level. A method is described for producing rapid and efficient cooling by this technique, such that the temperature of the cooled gases is essentially independent of both flame temperature and ambient temperature. The method involves passing the high- temperature gas through bulk arrangements of chemicals which decompose endothermically and produce further gases that mix with the propellant gases. The resultant mixture has increased mass and a greatly reduced temperature. Advances in chemical coolant-heat exchanger technology as related to propellant gas-generating systems are described. In particular, design data for specific propellant-coolant systems are discussed, with emphasis on their use for inflatable devices.
