Disclosed is a magnetic fluid acceleration system based on a wind tunnel and an acceleration optimization method. In the system, a nanosecond pulse generator can adjust parameters, and the parameters include pulse rising edge, pulse width, amplitude and frequency, and the vacuum chamber body is configured as a sealed structure , the heating unit is arranged inside the vacuum chamber body to adjust the temperature, the air pressure control unit communicates with the inside of the vacuum chamber body through the air hole to adjust the air pressure, and the upper electrode dynamically and sealingly penetrates through the upper surface of the vacuum chamber body, The lower electrode seals through the lower surface of the vacuum chamber body. The upper electrode and the lower electrode form a discharge gap with a predetermined distance inside the vacuum chamber body. The predetermined distance is adjusted by adjusting the upper electrode. The permanent magnet is arranged on the vacuum chamber body. An adjustable magnetic field is generated inside the vacuum chamber body, the magnetic field covers the discharge gap to accelerate the magnetic fluid, and the electrical parameter measuring device is configured to measure the voltage and current characteristics of the discharge gap.
Description
technical field [0001] The invention relates to the technical field of wind tunnels, in particular to a wind tunnel-based magnetic fluid acceleration system and an acceleration optimization method. Background technique [0002] The simulation test capability of wind tunnel is of great significance to the development of aircraft. With the development of the aerospace industry, the flight speed of the aircraft is increasing day by day, from the subsonic speed to the hypersonic speed.
