Hypersonic Boundary Layer Interference Control Method Based on Flow-Oriented V-Shaped Sliding Arc Array

Abstract

This invention proposes a plasma actuator based on a flow-oriented V-shaped sliding arc array. The base plate adopts an integrated stepped structure, and multiple sets of V-shaped electrode cavities are arranged sequentially along the flow direction in the upper base plate for placing copper electrodes. Tungsten needle electrodes penetrate the upper base plate and are electrically connected to high-voltage resistant silicone wires that penetrate the lower base plate. A power supply circuit for the plasma actuator based on the flow-oriented V-shaped sliding arc array is also provided, including a DC power supply, a high-voltage pulse power supply, first and second electronic switches, first and second resistors, first and second high-voltage silicon stacks, and an array formed by several V-shaped sliding arc plasma actuators connected in series. Furthermore, a method for controlling hypersonic boundary layer interference based on a flow-oriented V-shaped sliding arc array is provided. This invention can effectively control shock wave / boundary layer interference, suppress flow separation, and optimize aerodynamic performance in hypersonic flow control, and has broad application prospects.
