摘要
以往的地面风洞实验研究表明等离子体流动控制具有极大的实用价值。为探索等离子体流动控制应用的关键技术,开展了低速无人机等离子体流动控制飞行验证研究。首先,设计了无人机试飞实验系统和试飞方案,据此进行激励特性测试和地面风洞实验,测试了毫秒脉冲等离子体激励的放电特性,在风洞中验证了毫秒脉冲等离子体流动控制对Viper Jet无人机失速分离的控制效果。然后,进行了Viper Jet无人机等离子体流动控制飞行验证,结果表明AC-DBD激励能有效减小飞机起飞与降落滑跑距离。
It is of interest to study the plasma flow control on the ground wind tunnels.In order to explore the key technology of plasma flow control in application,the flight verification research on low speed UAV plasma flow control is carried out.Firstly,both these UAV test flight test system and the flight test plan are designed.On these grounds,the excitation characteristics test and the ground wind tunnel experimental study are carried out.The discharge characteristics of the plasma excitation are tested,and the harmonic pulse flow control to the Viper Jet UAV stall separation is verified in the wind tunnel.Then,the Viper Jet UAV plasma flow control flight verification is carried out.The results show that the AC-DBD actuation can effectively reduce the take-off distance and the landing distance for Viper Jet UAV.
