Abstract
An experimental study of the self electromagnetic field generated by the low-temperature plasma of the fuel combustion products of a model liquid-propellant rocket engine is carried out. The fuel components were gaseous oxygen and ethyl alcohol. When modeling emergency situations in the operation of the model rocket engine, the intensity of its self electromagnetic field generated by the ionized products of fuel combustion was recorded. A linear dependence of the self magnetic field strength on the pressure in the combustion chamber in the range 2.2–3.5 MPa was established. The feasibility of noncontact electrophysical methods for diagnosing the working process in aircraft power plants using as a useful signal the value of the magnetic field strength is shown.
