16 Figure 3-7. Maximum Fairing Spot Temperature Seen by Rideshare Payload 3.3.10 FREE MOLECULAR HEATING
The maximum free molecular aero-thermal heating rate experienced by the Payload is less than 3,500 W/m
at fairing separation. Free molecular aero-thermal heating declines significantly and becomes negligible over the next couple of minutes. 3.3.11 PAYLOAD CONDUCTIVE BOUNDARY TEMPERATURES
Bounding hot and cold boundary temperatures and conductance values at the interface of the Payload and the SpaceX- provided Mechanical Interface
, described in Section 4.2.4, are shown in Table 3-13 and Figure 3-8. Customer may use these boundary conditions to run a Payload-specific thermal analysis. Note that these boundary conditions are only relevant after Liftoff at Time = 0 as they contain analysis uncertainty that is not appropriate on the ground. The convective environment in Table 3-1 fully defines the pre-launch environment. A Mission-specific analysis will not be provided by SpaceX. Verification Testing is ADVISED to the combined thermal vacuum and thermal cycle test levels and durations defined in Table 3-15 in accordance with the environments defined in this section.
