摘要

摘要: 实验依托搭建的螺旋桨等离子体流动控制测试平台,基于等离子体附壁射流抑制边界层分离的两种机制,采用等离子体射流与来流方向相同的正向射流方式和与来流方向相反的逆向射流方式,研究了微秒脉冲等离子体射流对螺旋桨三维流动分离的控制效果,对比分析了两种射流方式增效特点.实验结果表明:在螺旋桨转速为300r/min,电压峰值为8.5kV,脉冲频率为10~160Hz范围内,正向射流有利于减小螺旋桨转矩,逆向射流对转矩的效果则相反.两种射流方式均提高了螺旋桨拉力和效率,同时其控制效果受脉冲频率的影响较大;正向和逆向两种射流分别使螺旋桨效率最大提高了11.56%,2.79%.

Abstract: Based on two kinds of mechanisms that the attached wall plasma jet restrains the boundary layer separation, the experiment was operated to study the microsecond impulse plasma jet control performance at three-dimensional flow separation of propeller supported by the experiment platform for propeller plasma flow control. According to the mechanisms, two kinds of plasma jets, synclastic jet in the same direction of airflow, and reverse jet in the opposite direction of airflow, were used in the experiment. It is found that when the propeller rotation speed is 300r/min, voltage amplitude gets 8.5kV, and pulse frequency is within the range of 10-160Hz, the twisting moment of propeller decreases with synclastic jet and increases with reverse jet. The thrust and efficiency of propeller both are improved under the control of two kinds of plasma jets, but the plasma flow control performance is obviously influenced by pulse frequency. In the experimental conditions the propeller efficiency increases 11.56% with synclastic jet, and 2.79% with reverse jet respectively.
