3.1.3 Establishing temperature distribution at the shoulder and
stagnation point regions
During Super-Orbital re-entry, as the flow progresses away from the
stagnation point in all directions in a 360 degrees pattern, the
magnitude of temperature field also gradually decrease down to shoulder
ends [14]. Same principle applies to shock and boundary layers. This
leads to a proportionate decrease of the surface temperature. According
to Scalabrin [15] and Zeng [16], the temperature value at the
shoulder regions is not lower than 90% of the stagnation point value
(peak value) for Orion MPCV. This is further explained in Fig.3.4 and
3.5.
