F-Atom Depletion in NF3 Combustor Laser Flows.

Abstract

Chemical lasers employing NF3 combustors operating at temperatures below 1900 K are subject to F atom depletion because of NFx (x=1,2) radical chemistry. Experiments using arc-heated arc-heating NF3-He mixtures have shown that the F atom flow stagnation temperatures of 1000 to 1600 K is significantly reduced while considerable NF chemiluminescence is observed. A method for obtaining F atom flow from low temperature combustors is described.
