Wind-tunnel measurements with a principal fighter-type aircraft model on a dynamic balance are discussed. The principal fuselage with closed engine inlets could be combined with three wing configurations, swept back wing, rhombic wing and delta wing and additional horizontal and vertical stabilizer modifications. One more variation could be made by a strake. The aim of this investigation is measuring the influence of wing shape, stabilizer configuration and strake on the dynamic derivatives of the longitudinal and lateral motion and to compare these results with theoretical computations. This comparison made it obvious, that existing theoretical methods could not describe special physical phenomena, which occur at higher angles of attack.
