Development of thermal assessment technology is crucial to the security assessment of hypersonic vehicles. A strategy of high-precision reconstructions of nonuniform heat flux and temperature field characteristics of a hypersonic vehicle surface by a scanning electron beam is constructed, and a fraction frequency and random scanning mode that can significantly reduce the temperature fluctuation of materials is proposed. The reconstruction effects in this scanning mode are successively investigated in the HIFiRE-5b flight condition and the reentry condition of the capsule of Apollo 6, showing that the reconstruction accuracies of the heat flux and temperature fields are within 2 and 5%, respectively, and the temperature history is accurately reconstructed with an amplitude of temperature fluctuation below 11 K. This research is expected to promote the electron beam thermal assessment to reconstruct the thermal boundary conditions of hypersonic vehicles more realistically.
