Abstract : This paper proposes a new representation of aerodynamic reactions in terms of the motion variables, which does not rely on assumptions of linearity. This representation is therefore indicated for extreme flight conditions where a locally linearized model is usually of questionable value. The significance within the present context of stability derivatives is discussed with the intention of pointing out their range of applicability. A wind-tunnel technique, capable of efficiently obtaining the bulk of the data required for the effective use of the above representation, is briefly described.
