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.
