Addendum to nose cone heating: stagnation temperature

It’s useful to calculate the stagnation temperature of the air. It gives an upper bound to the temperature that the nose could reach.

Altitude (m) Velocity (m/s) Temp (K) Pressure (Pa) Mach number Stagnation temp (K)
827 344 282.8 91777 1.02 341.7
2022 532 275.0 79278 1.60 415.9
8056 360 235.8 35312 1.17 300.3
9955 780 223.4 26619 2.60 526.2
11750 1112 216.7 20108 3.77 831.9
