Abstract:

The results of wind tunnel tests to determine the stable characteristics of slender cones and right circular cylinders at large angles of attack are presented at a test Mach number 2.87. Five cones of fineness ratio 4.5 with center of gravity locations 55.0 and 66.7 per cent body length were tested along with 3 cylinders of fineness ratios 5, 10, and 20. The Ld 4.5 cone models, which were suspended at the theoretical center of pressure, stabilized at the 0 degree angle of attack position if released from angles less than 50 degrees. When these configurations were released at angles greater than 50 degrees, a tendency to stabilize near the 90 degree position was indicated. The cone models which were suspended forward of the theoretical center of pressure 55 per cent were quite stable and stabilized at 0 degree angle of attack for all release angles. The cylinder models stabilized at about 90 degrees angle of attack confirming the results of Raymond and Garber. Author
