I'm wondering if there is a centering rIng size guideline for specific motors or thrust ratio to ring or centering sleeve size?
Pay particular attention to page 4, where he starts talking about attachment points. That is absolutely true. The highest likelihood of failure comes from the rings detaching from the MMT or the booster, not from the rings crumpling or shredding. Three CRs well-epoxied, with the epoxied areas pre-sanded/scuffed, is plenty sufficient. My level 3 rocket has three plywood CRs, pretty thick. But if the glue-joints broke, watch out!Duh. Apogee newsletter. Of course. Good info.
