The external region stagnation point in Fig.2.3 seems to be very cold
(400\(^0\)C) compared to the immediate surrounding
temperatures (1000\(^0\)C). This does not reflect a true
hypersonic re-entry temperature of Orion heat shield where stagnation
point is the hottest. Effort to improving the temperature irregularities
in Fig.2.3 gives the geometry in Fig.2.4. The primary idea is to achieve
a better thermal distribution by redesigning prototype model to spread
concentrated heat across the entire heat shield.
