Abstract: The coating technology of liner on a rocket motor is a model-covering process and the processing properties are closely related with the rheological behavior of liner slurry.By means of analyzing the coating course of motor liner, it is suggested that the swabbing technology which should deal with swabability,sagging-restricting and flow level can be described by swabbing force,yield value and flow level time,respectively.The experimental results showed that the relation between the practical swabbing behavior and the rheological properties of a liner slurry are in good agreement with the theoretical analysis.As a result, the way to it is pointed predict,evaluate and control the coating characteristics of rocket motor liner by the aid of the testing rheological parameters of liner slurry was suggested.
