Abstract
Real time X-ray radiography system was used to observe the slag accumulation and flow of back wall region of submerged nozzle in solid rocket motor. Data and image were obtained. The main conclusions are as follow: (1) There exist slag particles in all back wall region, the particle concentration is lower in the center of back wall region. (2) When the submerged depth varies from 23mm to 33mm, the slag weights increase. (3) As the aera of nozzle throat reduces, the slag accumulation also increases.
