The Lateral Stability of Aeroplanes: Derivative Calculation by the Lotz System

SYMMETRIC AND ANTI‐SYMMETRIC WING LOADING DISTRIBUTIONS IT is proposed to work out the span loading distribution and lift and drag coefficients of an unstalled wing in symmetric flight, together with the wing rolling and yawing derivatives for rolling and yawing flight. The only data assumed are a knowledge of the geometry of the wing and of the slope of the lift‐incidence curve of any section of the wing when referred to infinite aspect ratio.
