Experimental estimation of functional capabilities and temperature error of microwave sensors of combustion processes.

Temperature regime of the sensors, controlling flame electron density Ne in chambers of thermal power engines, has been investigated in this work. By detailed analysis of electrical and thermal processes, suggestions, improving thermal regime of the sensors, reducing temperature error and increasing their life time, were made. Experiment has proved the opportunity of using microwave sensors for advanced flame diagnostics in all air get engines and other thermal power engines (TPE).
