固定壁面激波控制技术在进气道特性调节、飞行器气动力控制等方面有着重要的应用前景,对该领域的研究进展进行了综合分析。从工作原理来看,目前的固定壁面激波控制原理主要包括局部能量添加、局部质量添加、直接力控制三大类,而具体实现方法则有多种,其中近壁等离子放电控制、分布式二次流注入控制、磁流体控制均完成了控制原理验证试验,并获得了较好的控制效果,具有较高的研究价值。并且,基于近壁等离子放电、分布式二次流注入的激波控制技术均已经完成了对应固定壁面可调进气道的风洞试验。然而,各种固定壁面斜激波控制技术离实用还有一定距离,特别是存在高浓度等离子体的低功耗产生方法、次流/主流混合边界层发展特性等基础性问题需要重点研究解决。
Fixed-wall shockwave control technology has important application prospects in the adjustment of inlet characteristics, aerodynamic control of aircraft and so on, and makes a comprehensive analysis of the research progress in this area. From the working principle point of view, the current fixed wall shock wave control principle mainly includes local energy addition, local mass addition, direct force control three categories, and there are a variety of specific methods, including near-wall plasma discharge control, distributed two The secondary flow injection control and the magnetic fluid control have all completed the control principle verification test, and obtained the better control effect, which has a higher research value. In addition, both the shock wave control technology based on the near-wall plasma discharge and the distributed second-flow injection has completed the wind tunnel test corresponding to the adjustable inlet of the fixed wall. However, all kinds of fixed wall slant shock control techniques are far from practical. In particular, low-power generation methods for high-concentration plasmas and basic problems such as secondary / mainstream mixed boundary layer development characteristics need to be studied and solved.
