Abstract:

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)
