Abstract: |
Submerged inlet is often considered as a slightly S curved divergent duct with no more elaboration than careful shaping of the duct entrance fo facilltate inlet flow.Performance of such an inlet is handicapped by its position inside the missle.The innovative design concept presented herein makes it possible to achieve the performance that is superior to all test results hitherto known to the author |
Key words: Submerged inlet + Inlet test Total pressure recovery coefficient of inlet |
