The purpose of this paper is to provide nonlinear parabolized stability equation (NPSE) analysis of stationary crossflow vortices within a hypersonic boundary layer. EPIC is a new NPSE capability developed within the Computational Stability and Transition Laboratory at Texas A&M. Results for the 7° half-angle straight cone geometry at 6° angle of attack are presented in this paper. Comparisons with the experimental results of Craig & Saric (2014) in the Texas A&M Mach 6 Quiet Tunnel are provided. Techniques for modeling stationary crossflow vortex paths and the evolution of spanwise wavenumber derived solely from the basic state solution are presented and verified via the DNS solution of Balakumar & Owens (2010).
