An Experimental Study of Electrophysical Characteristics of Gas Flow when Bench Testing Elements of Flow Ducts in Ramjets

This paper presents the results of an experimental study of the natural electromagnetic field of a supersonic jet of products of combustion in a ramjet engine operating on hydrocarbon fuel. An increase in the amplitude of the magnetometer signal of the gas flow when such fuels are burned is registered. The relative strength of the induced magnetic field of high-temperature products of combustion, registered by a magnetic sensor in the critical section of the ramjet combustion chamber is assessed. An increase in the amplitude of the magnetometer signal is experimentally determined on fuel combustion modes, which can be used as a diagnostic indication for monitoring the technical condition of the engine in the process of bench firing tests.
