Question

uo u (b shock u U2 shock Consider a blunt reentry vehicle in the atmosphere moving with a velocity uo 3.4 km/s in the upper atmosphere with the effective temperature t-10°C, effective average molecular weight M 24, and effective ration of specific heats y 1.34. The supersonic air flow with respect to the reentry vehicle forms a shock in front. Consider two regions, as shown in the figure, (1) where the air flow velocity is normal to the shock and (2) where the flow velocity vector u, is away from the normal to the shock by the angle of ф-6.0° a) Calculate the flow Mach number, M, and velocity, u, after (downstream) the normal shock in front of the body b) calculate velocity u of the flow after (downstream) the oblique shock c) calculate the angle o of the change of the direction of the flow at the oblique shock crossing
