An Investigation of Nose Bluntness Effects on Transition Asymmetry and Transition Aerodynamics

Abstract

The effects of wind fixed boundary layer transition on reentry vehicle aerodynamics plays an important role in determining high altitude trajectory dispersions. An investigation was undertaken to determine the effects of nose bluntness on boundary layer transition asymmetry and transitional aerodynamic perturbations at angle of attack. The results of previous experimental investigations of asymmetric transition are reviewed. An experimental program using the Calspan 96-inch shock tunnel to investigated bluntness effects on transition asymmetry and related aerodynamic perturbations is discussed. Data from the test program will be published in a future report.
