The paper considers the problem of a payload heating under exposure to the atmosphere affecting the payload fairing the launch vehicle second stage flight segment. Maximum heating of the Soyuz-2.1 payload fairing conical shell is examined for the case of launching the Glonass-K2 spacecraft. Computation data are compared with the experimental values, and satisfactory results are obtained. Predictive dynamics in the payload fairing jettison is identified. Energy reserves are assessed, as well as the economic benefits obtained by optimizing the payload fairing jettison time. Static processing results are provided for the Soyuz-2.1 launch vehicles of all types and the Angara-1.2 launch vehicle for 10 tests.
