Abstract

A high-fidelity prediction of near-field sonic-boom signature is performed. Three benchmark cases (including an axisymmetric body, a simple delta wing-body, and a complete low-boom supersonic transport configuration) and the Lockheed Martin 1021 (LM1021) case are simulated with a hybrid grid Reynolds-averaged Navier-Stokes solver, HUNS3D, to predict near-field sonic-boom signature. Overall, the computational results agree well with the wind-tunnel experiment data. The influence of geometrical modification, grid size and distribution, spatial discretization schemes, and viscosity are studied and analyzed. The near-field signature of the LM1021 configuration propagating to the ground is analyzed by a linear wave approach.
