Abstract
An experimental study of the electromagnetic field generated by the low-temperature plasma of the fuel combustion products of a model liquid rocket engine was carried out. The components of the fuel were gaseous oxygen and ethyl alcohol. When simulating emergencies in the operation of a model rocket engine, the own electromagnetic field strength generated by the ionized fuel combustion products was recorded. A linear dependence of the magnetic field strength on the pressure in the combustion chamber is established in the range of 2.2-3.5 MPa. The possibility of using non-contact electrophysical methods for diagnosing the working process in power plants of aircraft using the value of the magnetic field strength as a “useful” signal is shown.
