Abstract : The prediction methodology of dynamic derivatives is presented as derived from semiempirical calculation procedures like 'USAF Stability and Control Datcom' in combination with some modifications necessary for tactical missile configurations at higher angles-of-attack. The main subject is the longitudinal stability derivatives and the roll damping derivativum. A comparison of theoretical and experimental results is presented where different dynamic wind tunnel test equipments are explained including the data evaluation theory. Some aspects of modification of the present linear data evaluation method to nonlinear terms at high angles-of-attack are shown with an example of a fighter aircraft configuration using the MOD test rig in the Dornier wind tunnel.
