ESDU 84002 demonstrates how methods given elsewhere in the Series for estimating the contributions to the derivatives Yr, Nr and Lr due to individual major parts of the airframe (wing, bodies, flaps and fin) may be combined to provide values for the complete aircraft. The overall accuracy achieved is illustrated by correlation plots showing comparison of prediction with flight-test and wind-tunnel results drawn from many sources in the literature; for a diverse range of configurations broadly Yr is predicted within 0.05, Nr within 0.025 and Lr within 0.02. A simplified method for estimating complete aircraft yawing derivative values is also included.
