Abstract:

A chain-reaction CO chemical laser fueled by carbon monosulfide CS and molecular oxygen O2 has been demonstrated. Initiation by the chain carriers either O-atoms or S-atoms is necessary the chain length lambda increases rapidly with CSCS2 fuel mole ratio reaching a value lambda approximately equal to 9.5 at CSCS2 1.57. Mass flow efficiencies up to 67 kJlb sub m have been measured with a small-scale subsonic device, and laser operation has been observed up to 64 Torr cavity pressure. Gain measurements, mixing effects, and computer modeling of this system have been investigated. This work was made possible by the development of a thermoelectric CS gas generator, which is also described.
