    NASA has extensive technical knowledge of head loading during
    hypersonic re-entry. Heating of various geometries of edges in
    supersonic flight is in the literature.

    Just as in stationary bodies.
    Solve in rest frame, then Lorentz transform,

    Is that true? I thought temperature was poorly defined in accelerating frames- or at least comparing temperatures between two accelerating frames was problematic- and so heat flow, which is driven by temparature gradients, would seem to be non-trivial as well.

    Wasn't there a recent experiment about this?
