Abstract

In this work we develop a methodology for simplified calculations of the force and moment experienced by a shock impinged ISS component during atmospheric entry. Utilising blast wave theory we develop a correlation for scaling a single computationally calculated force and moment to flight relevant conditions. Our baseline computational model is selected to match a model previously tested in the TUSQ hypersonic facility. The force results of the computation match the experimental results to within 10%. With the validated computational result, we then compute the scaled loads for three different flow conditions expected to be a part of the ISS re-entry trajectory, computing an
increase of axial shear force from 9.3 kN to 110 kN when going from an altitude of 80 km down to 60 km. The methodology developed in this work provides a mechanism for implementing higher fidelity aerodynamic loading into break-up modelling of complex structures.
