The electric current formation in aircraft jet engine ducts and the electric current flowing into the gas dynamic wake behind a heated blade have been simulated experimentally. Two models were used in the experiments: a cylindrical metal channel through which a high-temperature gas flows and a metal blade (from a blade engine) in a high-temperature jet. The working medium was created in a gas-burning apparatus in which a propane jet was diffusively burned in a wake air flow. The dependence of the electric engine current on the air flow rate in the wake is given. The results obtained are qualitatively explained.read more

Theory of Disappearance of the Electric Signal Induced by an Aircraft Jet Engine in the Afterburner Regime
A. B. Vatazhin,K. E. Ulybyshev +1 more
TL;DR: In this article, the disappearance of the engine current and alternating electric signal induced by the engine jet in the afterburner regime, is explained, and it is shown that this phenomenon results from the detachment of electrons from negative ions when the gas temperature in the Afterburner increases, leading to an increase in the effective conductivity of the gas.

Electric Diffusion Processes on a High-Temperature Turbine Blade and Its Contribution to the Aircraft Engine Current
TL;DR: In this paper, the effect of disturbance of the electrical neutrality of flow in the channel of a jet engine is investigated, which leads to the emergence of an electric current flowing out of the engine (engine current) and, as a result, to engine electrization of the aircraft.
