Hydrazine perchlorate flame temperature

The experiments performed in this program are grouped into (a) experiments in which vaporization rates of pure hydrazine perchlorate were measured (b) deflagration rate measurements (c) temperature profile measurements (d) flame temperature measurements. 

Flame Temperature Measurements. Thermodynamic calculations of the nature of the products of hydrazine perchlorate self-deflagration at a series of processes were performed by an IBM-7090 computer program. The results are shown in Table V. The calculations were made assuming... 

Since it has been found that the self-deflagration of ammonium perchlorate does not lead to the products calculated on the basis of thermodynamic equilibrium, we felt it desirable to measure the flame temperature for hydrazine perchlorate. A flame temperature appreciably different from that calculated would indicate a nonequilibrium distribution of products which would require investigation. 

Preliminary experiments were performed in which lengths of 1-mil platinum wire were stretched through the center of tamped strands of hydrazine perchlorate. Examination of the wire after deflagration showed that the passage of the flame had melted it. The melting point of platinum is 2042° K. and the heat loss by radiation was estimated at about 40° K. This placed the flame temperature as somewhere above 2082° K. 

Flame temperature measurements by the sodium line reversal method were made with hydrazine perchlorate strands containing 2% thiourea and 2% sodium chloride. This amount of sodium chloride was necessary to achieve a sufficient intensity of emission of the sodium D-line for these experiments. It may be pointed out that in oxygen-rich, chlorine-containing flames such as this, the concentration of sodium atoms is decreased...
