Book Description
Abstract: An investigation of the pressure distribution for a body of revolution, consisting of a 33-1/3-caliber (5.75 fineness ratio) tangent ogival nose and a cylindrical afterbody, has been made for an angle-of-attack range of 0° to 35.5° at a Mach number of 1.98 and a Reynolds number of approximately 0.5 x 106m based on body diameter. Comparisons of the theoretical and experimental pressure distributions are made to show the nature of the effects of both viscosity and cross-flow compressibility. The experimental load distributions are compared with those predicted by the method suggested in NACA RM A9I26 which includes an approximate method for taking into account the effects of viscosity on the lift distribution.
