AI Technical Summary
Conventional supersonic airflow generators cannot adjust the critical cross-sectional area, resulting in limited experimental conditions and requiring the replacement of the entire Laval tube to adjust parameters, which is time-consuming and costly.
A switching mechanism is adopted, including multiple chucks and rotating rods. The switching of throat channels with different diameters is realized by the rotation of the chucks and the positioning mechanism. Combined with the contraction transition channel and the diffusion transition channel, the critical cross-sectional area is adjusted to control the airflow parameters.
It enables rapid adjustment of supersonic airflow rate and Mach number to meet different experimental needs and reduces equipment maintenance costs and time.
