Abstract
In order to extend the state-of-the-art aerodynamic coefficient prediction methodology at high angles of attack, a semi-empirical prediction technique has been developed for the prediction of normal force and pitching moment coefficients for slender body alone and slender body plus fin configurations. Additionally, installed fin normal force, root bending and hinge moment coefficients are calculated. The semi-empirical prediction technique is valid for slender bodies with low aspect ratio fins at Mach numbers from 0.6 to 3.0 and angles of attack from 0 to 180 degrees. The range of validity of the prediction technique for the low aspect ratio fins is: aspect ration from 0.5 to 2.0; taper ratio from 0 to 1.0 and span ratio from 0.3 to 0.5. Wind tunnel testing was accomplished in order to provide the data base from which the prediction technique was derived. The data base provides the first parametric set of data at angles of attack, from 0 to 180 degrees, and not only provided the base for the semi-empirical prediction technique developed herein, but will provide a standard of comparison for high angle of attack prediction methodology developed in the future.
