Abstract

The invention belongs to the technical field of scramjet engine fuel injection and flame stabilization and combustion organization, and discloses a slippage arc discharging enhanced supersonic air-mist mixing burner. The slippage arc discharging enhanced supersonic air-mist mixing burner comprises an installation base plate. A supporting plate body is arranged on the installation base plate, array-type sliding arc discharging modules are arranged on the tail portion of the supporting plate body, the array-type sliding arc discharging modules are electrically connected with a high-frequency high-voltage power source, a fuel injection rod is arranged in the tail portion of the supporting plate body in an inserted mode, a cavity is formed in the fuel injection rod, and liquid fuel injection holes communicating with the cavity are formed in the fuel injection rod. According to the slippage arc discharging enhanced supersonic air-mist mixing burner, the structure is simple and compact, andthe functions of liquid fuel injection, atomization, mixing enhancement, ignition and combustion enhancement are integrated.

Description

technical field [0001] The invention belongs to the field of scramjet fuel injection and flame stabilization technology and combustion organization technology, and in particular relates to a slip arc discharge enhanced supersonic gas mist mixing burner. Background technique [0002] The scramjet engine has no self-starting capability, and the typical flight work process is to ignite and start under the condition of Ma4, and continuously accelerate to reach the cruising condition of Ma6. Under these two working conditions, the gas flow state of the combustor presents different characteristics. Under low Mach start-up conditions, the total temperature of the incoming flow is low, and the fuel cannot achieve self-ignition, and an external energy excitation is required for forced ignition. As the flight Ma number increases, the total temperature increases continuously, and the ignition location is determined by the ignition delay time. At the same time, supersonic combustion h...
