Paper Abstract

The experimental method and results of impingement field of real rocket exhausted jet are presented. By using large aperture and long path moiré deflector, the moiré deflectograms of rocket free jet and rocket jet impingement field are obtained. From these moiré deflectograms, the location of Mach disk, oblique shock wave and the value of boundary are calculated quantitatively, and compared with the results of numerical simulating and wind tunnel simulating. At the same time, we have found five new shock wave structures from the experiments.
