Abstract:

Calculations are presented of the hypersonic flow around an elliptical cone oriented at a 30 deg angle of attack in air flows with speeds of 2350, 3356, and 6713 msec. The air was treated as a three-component nitrogen, oxygen, and nitrogen gas, and its thermodynamic functions were calculated by a standard program. The results are graphically compared with those for a perfect gas. The second part of the study shows the calculated behavior of life, drag, and pitch-moment coefficients in a perfect gas as functions of three vertex angles and angles of attack from 30 to 50 deg at Mach 7.
