Publisher's Synopsis
Two airfoils are used on the main rotor blade of the UH-60A helicopter, the SC1095 and the SC1094 R8. Measurements of the section lift, drag, and pitching moment have been obtained in ten wind tunnel tests for the SC1095 airfoil, and in five of these tests, measurements have also been obtained for the SC1094 R8. The ten wind tunnel tests are characterized and described in the present study. A number of fundamental parameters measured in these tests are compared and an assessment is made of the adequacy of the test data for use in look-up tables required by lifting-line calculation methods.Bousman, William G.Ames Research CenterAERODYNAMIC CHARACTERISTICS; AIRFOILS; WIND TUNNEL TESTS; ROTOR BLADES (TURBOMACHINERY); UH-60A HELICOPTER; PITCHING MOMENTS; LIFT DRAG RATIO; MACH NUMBER; ANGLE OF ATTACK; SUBSONIC SPEED; FLIGHT CONDITIONS; REYNOLDS NUMBER; TRANSONIC WIND TUNNELS...
