The results indicate that the pulsed extraction column provides high operating capacity and stability using a standardnozzle plate rather than other cartridge geometry nozzle plates.
The standard deviation of four-nozzle impinging flame noise was greater than that of the two-nozzle impinging flame noise, but the change of the standard deviation was the reverse.
The calibration equipment is used to calibrate the visual testing system for rocket nozzle 3D motion, and supplies the standard position and motion parameters for static and dynamic calibration.
