Abstract

A micro-vortex generating device with airflow auxiliary control, which mainly includes a high-pressure air supply circuit, an airflow auxiliary control device, a microvortex generator (14), and a supersonic controlled surface (13). The aerodynamic configuration similar to that of the micro-vortex generator is formed on the supersonic controlled surface. By controlling the solenoid valve, this aerodynamic configuration can be changed, and the control effect of the micro-vortex generator can be improved through airflow assistance. At the same time, it is extremely It greatly broadens the applicable working conditions of the micro vortex generator.

Description

technical field [0001] The invention relates to a micro-vortex generating device for airflow auxiliary control, which belongs to the field of supersonic aircraft control. Background technique [0002] Complicated flow separation generally exists in the internal and external flow fields of supersonic vehicles. This phenomenon leads to a sharp increase in wall turbulence and viscous dissipation, leading to adverse consequences such as increased drag, reduced lift, and premature stall. The nearby flow field is distorted, the total pressure recovery drops, the engine does not start, etc. Therefore, searching for an efficient and stable flow separation technology has become one of the important topics in the current high-speed aircraft technology research. [0003] Because of its simple structure and good control effect, the micro-vortex generator has become the most common technology in supersonic flow control. The micro-vortex generator will form a series of vortex ring struc...
