Abstract

The invention discloses an electrode for an aeroengine and an aeroengine composed thereof. The electrode includes a temperature-resistant and conductive electrode inner core and a temperature-resistant and anti-corrosion electrode outer wall, and the electrode outer wall is wrapped around the exposed surface of the electrode inner core. A plurality of electrodes are installed in the combustion chamber of the engine, and the plurality of electrodes are capable of generating an electric field in the combustion chamber. The electrodes of the present disclosure can be installed in the combustion chamber, and the electrodes can be controlled to output different voltages through an external electric field control device, so that electric fields can be generated between different electrodes. The electrodes are arranged at different positions in the engine combustion chamber to generate axial , Radial or oblique electric field, the output voltage of the external electric field control device and the control voltage change can realize the controllable electric field between the electrodes.

Description

Electrode for aero-engine and aero-engine composed thereof technical field The present disclosure belongs to aero-engine technical field, be specifically related to a kind of electrode for aero-engine and composition thereof aircraft engine. Background technique In terms of aero-engine control technology, the state control capability and continuous adjustment capability of the engine under different operating conditions [0002] It has an important impact on engine performance, life and reliability. With the development of engine control technology, the control components are reliable With the improvement of performance and the reduction of weight and volume, various advanced control technologies will be more and more widely used in different parts of the engine. pieces. However, in the control of the main combustion chamber, at present, only by adjusting the fuel pump, fuel valve, etc., the flow of fuel supply, The pressure is adjusted by the throttle, and the com...
