Near Magnetic Field of a Small Turbojet Engine

Different parameters like temperatures, pressures, speed, and vibrations are used in evaluation of technical state of turbojet engines. The article presents a pioneering idea to expand this set of parameters with measurements of distortions in magnetic field in a close vicinity of the engine to obtain more information about its state, which can be further used in its diagnostic and control systems. We believe that deviations in near magnetic field can hold valuable information, which can be used to predict malfunctions and evaluate the condition of the engine. The presented article shows pilot experimental results and gives answer to the basic hypothesis, if such measurements can be realized using a small turbojet engine, as well if there are significant changes in near magnetic field, which would warrant further research in the area.
