Title:
DESIGN AND PERFORMANCE OF A VARIABLE GEOMETRY DIFFUSER FOR AN AXISYMMETRIC WIND TUNNEl

Abstract:
To prevent the larger second throat area required for starting a supersonic wind tunnel penalizing the performance during the entire run, a diffuser was constructed with a movable centerbody. After the normal shock had been swallowed during starting, the centerbody was moved forward, thus constricting the flow area at the second throat. This allowed the normal shock, or shock system, to occur at a lower Mach Number, and therefore, reduced the losses.
