Abstract : The investigation of the use of light absorption signals in motor exhausts for determining motor burning rates was terminated. It is concluded that erratic absorption and diffraction from solid particles and the shock structure in the exhaust prevent this method from yielding useful results. Work concerning the effects of trace species on the electron concentration in combustion gases was initiated. The systems of interest always contain low ionization potential impurities, whose concentration is affected by the formation of compounds, stable at flame temperatures. The effect of sodium chloride formation on the concentration of trace amounts of sodium was measured. It has not yet been possible to provide a conclusive interpretation of this data based on either equilibrium or kinetic considerations. (Author)
