This paper analyzed the relationship between the vacuum degree and the throat area, shrinking degree of mixer, and the relationship between the maximum power and the vacuum degree and the throat area based on the engine mapping data. 作者在发动机台架试验数据的基础上,分析了混合器喉口面积、收缩(入口)角度与真空度(进气管进气压力)之间的关系;真空度、混合器喉口面积与发动机最大功率的关系。
The relationship between the maximum amplitude of HF impulse current superimposed in the emission current after compensating capacitive current of pre-breakdown current and vacuum degree under testing is directly and uniquely corresponding. 进行容性电流补偿以后,对发射电流中高频脉冲电流进行峰值检测,该峰值与灭弧室内真空度呈现单一对应关系。
