Open full text 0 citations

Abstract

The classification of the internal drags on sidewall-compression inlets was presented for the requirement of drag characters on scramjet.The walls inside of the inlet and captured flow tubes were used respectively to analyze drags.The total drag and component of different internal drag were given through numerical investigation.The influence of inlet configurations to the internal drag was discussed.
