A Method for determining the aerodynamic characteristics of two- and three-dimensional shapes at hypersonic speeds /

Some aerodynamic characteristics of several shapes are calculated, and it is shown that the lift and drag coefficients are dependent upon the thickness ratio, thickness distribution, and angle of attack.A method is developed for calculating the pressures on aerodynamic shapes at very high supersonic speeds in dense air with the ratio of specific heats equal to 1. The method is applicable to any body of revolution at zero angle of attack and to any two-dimensional profile. The results of the present paper are compared with previous work of Von Karman and Epstein on this problem and the difference explained.NACA TN No. 1613."July 1948."Includes bibliographical references.Some aerodynamic characteristics of several shapes are calculated, and it is shown that the lift and drag coefficients are dependent upon the thickness ratio, thickness distribution, and angle of attack.A method is developed for calculating the pressures on aerodynamic shapes at very high supersonic speeds in dense air with the ratio of specific heats equal to 1.
