Effectiveness of wheel-typed grain design for hybrid rocket motor performance

Although hybrid rockets are featured with distinct advantages over solid and liquid rockets, the issues specifically related to combustion instability and lowered regression rate are the most pronounced drawbacks which hinder it from being commercially viable. In the present work, we investigate t...
