Pre-ceramic resin was placed in a crucible in a tube furnace and pyrolyzed to 1600°C under Argon. The scanning electronic microscope (SEM) image was taken of the sample. The SiC crystals can be seen that were beginning to form on the surface.

Flower Powered Hypersonic Inlet with Bleed Perforations

Filed under the keywords

Mach (top) and pressure (bottom) contours for axisymmetric Busemann inlet with evenly spaced bleed perforations along length of inlet. Images show changes in Mach and pressure contours as a function of inlet length ranging from inlet start (left) and inlet throat (right). Contours were produced via Cart 3D, an inviscid code for automated CFD.
