Abstract : An ogive-cylinder body of revolution having a nose section 3 diameters long, tangent to a cylindrical body 7.7 diameters long was tested at angles of attack from 5 to 24 degrees at Mach numbers of 0.3 to 0.95 (Reynolds number of 0.44 x 10 to the 6th power). The effects of a large increase in Reynolds number at a low subsonic Mach number were also studied. These subsonic results supplement those reported in NACA Report 1371 for a similar body at Mach number 1.98 and the same test Reynolds number.
