Abstract : A component model computer program for the solution of poweron base pressure at supersonic speeds has been modified to (1) include the effects of the upstream boundary layers upon the free shear layers and to (2) incorporate the angular recompression criterion developed by ONERA for the wake closure condition. After the program modifications were completed, an extensive set of calculations were made for comparison with experimental data. These comparisons showed that, in general, the calculated base pressures are greater than the experimental base pressures. This lack of agreement raises questions about the applicability of a single stream recompression criterion to the solution of the two stream problem. (Author)
