Direct radiation from the propellants was compared with radiation from a Tungsten Strip Lamp. To date the wavelength range studied has been 6000 to 7000 Angstroms as selected by a Wratten No. 29 Glass Filter. Values for radiation emitted by the reference lamps were determined by simple photometric procedures using published absolute efficiency values for lamp operation at rated voltage and current for standard light values. Detector response to filtered light was measured by similar photometric methods. During propellant combustion, radiation was monitored by a photovoltaic cell silicon solar cell through the optical filter. The photoelectric signal level was displayed on a D. C. millivoltmeter and records were kept by photographing this meter and a second meter connected to measure smoke transmission.
