A blunt-body capsule is at Earth’s entry interface with entry speed vEI = 7.8 km/s. The capsule has ballistic coefficient C_B
= 65 kg/m2 . Plot the body-averaged heat-rate input (per unit skin-friction coefficient Cf) for a ballistic entry. Plot q_avg/C_f
as a function of altitude for two entry flight-path angles: γEI = –5^o
and –7^o
(place both plots on the same figure). Compute the critical altitudes for peak heating and the peak q_avg/C_f
values for both entry angles – do these values correspond to the peaks from the two plots?
