Nitrogen Scale-Up.
Abstract
Experiments are described which investigated the Continuous Wave (CW) scaling of excited nitrogen production in an H/NF2 reaction system. The purpose is to assess the potential for the development of an electronic transition chemical laser using N2(A) as an energy transfer donor. The experiments use a chemical laser combustor to produce fluorine atoms which are subsequently mixed with hydrogen to produce H-atoms. Heated tetrafluorohydrazine is subsequently mixed in the stream through a HYLYTE nozzle to initiate the H/NF2 chemistry. In a second series of experiments, NF3 was burned in the combustor to produce NF2 and F-atoms which were then mixed with H2 to initiate the desired chemistry. Relatively low yields of excited nitrogen were obtained in all experiments. The highest observed densities were of the order of 10 to the 12th power N2(A) and N2(B). Parametric plots used to optimize the system are presented. Keywords:Chemically reactive flows; Nitrogen fluorides.
