Abstract
This paper deals with the dynamic stability evaluation of a real aircraft using the results from a flying scaled model. Extended similarity criteria are proposed for the dimensional, inertial and the mass characteristics between the two models. The flight conditions preserves the lift coefficient. The results show that the damping factors for the Short and Dutch roll modes are the same both for the real aircraft and the scaled model. Factored values with a scale constant are obtained for the time characteristics in Short period , Dutch roll, “Roll” and “Spiral” modes. For the “Phugoid mode”, the numerical analysis point out that the ratio of the values of the damping factor for the real aircraft and the scaled model seems to be proportional with the ratio between the drag coefficient of the real aircraft and the drag coefficient for the scaled model.
