Infrared Measurements of Hypersonic Heating to Cubes

Le résumé fourni par la source

In order to better inform hypersonic heating predictions to faceted shapes such as satellites, the hypersonic heat flux to a cube is measured experimentally using infrared thermography. Stanton numbers across the entire surface of the cube are calculated, which involves the solution of a 2-D inverse heat conduction problem. As well as revealing notable 3D flow phenomena, the results show excellent agreement with Klett’s model for stagnation point heat flux to a flat surface. They also suggest that many current demise heating models struggle to accurately model heating to the sides and edges of cubes. The results also reveal the importance of taking model temperature changes as well as 2D and 3D conduction into account when calculating heat fluxes.
