Abstract
An investigation has been conducted in 1 ' x 1 ' trisonic tunnel of National Aeronautical Laboratory to determine aerodynamic characteristics of cone-cylinder and ogive cylinder bodies of nose fineness ratios of three, five and seven for angles of attack 0xB0; to 5xB0;? the afterbody fineness ratio being ten for all the models. 13; The results indicate . that the normal force is slightly higher for ogive cylinder body than cone-cylinder body of nose fineness ratio 3, and lower than cone-cylinder body for nose fineness ratio 7, and there is crossing of curves for nose fineness ratio equal to 5. This interesting phenomenon requires further investigation.
