After more research, discussion, and testing, the linear erosive model (see this post for more info) doesn’t seem to hold 100% true. Sometimes. This post is more of me thinking out loud about the subject in general, and attempts to tie up most of the theories into a neat, easily accessible post. So, here goes. (more…)

There has been a lot of discussion as of late regarding erosive burning and its relation to mass flux. Many have suggested that propellants with certain additives (notably, Oxamide) have a better response to high mass flux conditions, and have proven with ample results that it in fact does. While the effect these additives have is noticeable, it does not seem to scale linearly with pressure, as I might have expected thanks to the basic interpretation of Vielle’s law. After doing some thinking and some research, I happened upon some useful information on how to characterize the effect mass flux has on erosivity. (more…)
