The Influence of Real Properties of Air on Flow Parameters Around on Elliptical Cone. The Aerodynamic Characteristics of Elliptical Cones at Large Angles of Attack,
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 m/sec. 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.
