Performance Technology Program (PTP-S 2). Volume 14: Extensions to the 3DSAP approximate inviscid flow field code
Abstract
The 3DSAP approximate inviscid flow field technique has been modified to permit treatment of flared multi-conic afterbodies. The calculation of the flared afterbody section is performed using a discrete shock-fitting algorithm to accurately treat the embedded shock. Additional modifications have been incorporated into the code, allowing stretching of the body-normal coordinate grid and improving the treatment of expansion discontinuities on the multi-conic frustum.
