摘要

在航空发动机上运用等离子体助燃技术能够有效减少燃烧化学反应所需的活化能

提高燃烧效率。为了将该项技术真正应用到航空发动机燃烧室

搭建了三维旋转滑动弧放电等离子体助燃激励器放电特性的实验平台

采用实验与理论分析相结合的方法

探索环境压力对三维旋转滑动弧放电等离子体助燃激励器特性的影响。结果表明

在三维旋转滑动弧放电过程中

电弧在击穿伴随滑动模式（B-GI）和稳定电弧滑动模式（A-G）之间还存在一种过渡模式（B-GII）

同时具有以上两种模式特征。环境压力对电弧滑动模式影响显著

当压力小于1 bar（1 bar=0.1 MPa）时

电弧滑动模式随气压升高逐渐从B-GI模式发展为A-G模式。与此同时

随着环境压力的增大

电弧击穿电压和峰—峰值电压也随之增大

但由于放电过程中的电弧滑动模式转换

击穿电压在0.5～0.7 bar范围附近会有小幅度的减小。

Abstract

The application of plasma assisted combustion technology in aero engines can effectively reduce the acti-vation energy required for chemical reactions during combustion and improve combustion efficiency. In order to trulyapply this technology to the combustion chamber of aero-engine

an experimental system for the discharge character-istics of the three-dimensional rotary gliding arc discharge plasma assisted combustion exciter is established in thispaper. The combination of experimental and theoretical analysis is used to explore the influence of ambient pressureon the characteristics of three-dimensional rotary sliding arc discharge plasma assisted combustion exciter. The re-sults show that there is a transition mode（B-GII）between the Breakdown Gliding mode（B-GI）and the steady arcgliding mode（A-G）

which has two characteristics. The environmental pressure has a significant influence on thearc sliding mode. When the pressure is less than 1 ba（r1 bar=0.1 MPa）

the arc sliding mode continuously developsfrom the B-GI mode to the A-G mode as the air pressure rises. At the same time

with the increase of environmentalpressure

the arc breakdown voltage and the peak-to-peak voltage also increase. However

due to the arc slidingmode conversion in the discharge process

the breakdown voltage will decrease slightly in the range of 0.5～0.7 bar.
