CORRELATION OF SIDE-FORCE AND YAWING-MOMENT DATA FOR TACV CONFIGURATIONS AT LARGE ANGLES OF SIDESLIP

Methods developed by Woolard and Ruetenik and Zartarian for predicting the side force and yawing moment on TACV configurations due to side winds are compared against available data from wind-tunnel tests. The predicted side force based on slender-body theory is found in good agreement with the data from moving-ground plane tests for sideslip angles less than 5 degrees. Above 5 degrees, fair agreement is found by incorporating viscous-cross flow effects in the theory, although characteristic differences are observed from previous correlations for missile-type bodies. The measured yawing moment is 15 to 35% less than the slender-body prediction, and it differs markedly from viscous-flow predictions. (Modified author abstract)
