This paper provides linear parabolized stability equations analysis of a parametric hypersonic finned cone geometry. An automated meshing script is used to generate high quality grids for a given set of geometric parameters. The basic states are verified against direct numerical simulations and validated against Boeing/AFOSR Mach 6 quiet tunnel experiments. Grid convergence is also investigated by varying cell count and grid topology. By analyzing a number of paths defined by local inviscid streamlines, it is found that the second mode is the dominant mechanism on the geometry. Sensitivity of this instability mechanism to changes in geometry is examined by varying the sweep angle of the fin and the nose radius of the cone independently. Finally, trends derived from the geometric variation are discussed.
