Abstract

© 2015 by Tafara Makuni, Holger Babinsky, Michal Slaby, Christopher Sheaf. This paper presents results from a simplified experimental rig that aims to replicate the key physics of a transonic aircraft intake at high incidence for realistic altitudes. The equivalent flight conditions replicated are for free stream Mach numbers M ∞ = 0: 25 - 0: 45 and incidence angles in the range α = 30 ± 5°. Measurement techniques from the simplified two-dimensional geometric setup include; schlieren imaging, surface oilflows, pressure sensitive paint, pressure and temperature measurements. CFD models that look to predict this behaviour have a limited accuracy largely due to a lack of experimental validation data - this lends itself as one of the key motivations for the work presented in this paper. Currently there is good qualitative agreement between the experimental results and the initial computation(s).
