A thermal protection system for a vehicle may include a substantially rigid, relatively thin outer aeroshell, a relatively low density insulation layer, and a resiliently compressible conformal layer. The FCEHA may be part of a fluid-cooled electronic system that includes the FCEHA and a plurality of electronic components. The method presents a fundamentally new physical approach to the characterization of the spot weld quality.
