CO Chain-Reaction Chemical Laser Research.
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 CS/CS2 fuel mole ratio reaching a value lambda* approximately equal to 9.5 at CS/CS2 = 1.57. Mass flow efficiencies up to 67 kJ/lb 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.
