IHS ESDU Estimation of sideforce, yawing moment and rolling moment derivatives due to rate of roll for complete aircraft at subsonic speeds. 85010

ESDU 85010 discusses the application to the complete aeroplane of the prediction methods given in the Series for the contributions to the derivatives from wing planform and dihedral, and empennage. Illustrations show for diverse configurations at cruise the relative magnitudes of the contributions for each derivative, and comparisons with experimental data also show the effect of Mach number, incidence, wing sweep, and high lift devices. A detailed comparison of predictions with experimental data drawn from a wide range of sources including tunnel and flight results shows that the sideforce derivative is predicted to within 0.06, the yawing moment derivative to within 0.016, and the rolling moment derivative to within 10 per cent. A comprehensive worked example shows the application of the methods.
