Reducing the time and cost of aircraft creation can be achieved by improving the accuracy, informativity, and efficiency of flight research results on free flying dynamically similar models (FDSM). In particular, this is ensured by the development, improvement, generalization, and application of theoretical and methodological foundations for the creation of FDSM. This paper is structured from these positions. It does not reveal all the peculiarities of the design, manufacture, and testing of FDSM but shows the influence and dependence of altitude-velocity limitations of physical modelling problems on the main parameters of FDSM. At the same time, a literature review was performed to study and analyze the achievements and problems of physical modeling of aircraft flight on FDSM. The conditions and scales of similarity used in the design, manufacture, ground and flight tests of FDSM, and flight research are considered. The influence on the main parameters of FDSM of modelling problems, together with similarity conditions and the system of relations of parameters of FDSM, of the full-scale aircraft and environment; design conditions; technological limitations; flight-technical requirements; and operational limitations is emphasized. It is established that if mass is taken as the objective function in the design of an FDSM, then in order to achieve its minimum, one should strive to create an FDSM with the minimum possible linear sizes. To take into account the auto-model limitations of modelling problems, a special method for predicting flight characteristics and scientific-research capabilities of an FDSM has been developed and presented.
