Lasing Tests with Advanced Reactants.
Abstract
This report presents the results of an experimental program conducted to evaluate the lasing characteristics of liquid and gaseous combustor reactants; combustor reactants evaluated included oxidizers (F2, F2-N2 mixtures, NF3), fuels (H2, C2H4, C6H6(l), C6F6(l), CH1.95(l)), and diluents(He, N2, N20). Cavity fuel for all experiments was D2. Lasing tests were conducted using two types of nozzles: a slit-type 2-D nozzle and a tri-stream 3-D nozzle. Closed-cavity power was measured at varying operational conditions. Results showed that: (1) advanced reaction combustion was efficient and carbon free, (2) hydrocarbon liquid and gas fuel lasing performance levels were similar, and (3) fluorocarbon fuel performed better than hydrocarbon fuel at high combustor temperatures (3000 K) and poorer than hydrocarbon fuel at lower combustor temperatures (1500 to 2500 K).
