At all stages of the life cycle of unmanned aerial vehicles (UAVs), there is a need for experimental studies of their characteristics. In part, experimental studies of this kind could be performed on installations such as traditional wind tunnels. However, in existing wind tunnels, it is not possible to regulate the air flow speed and study the influence of the aircraft's center of mass position, as is required for evaluating the flight dynamics of modern UAVs. We present a fundamentally new concept of the laboratory stand and methodology for research of UAV aeromechanics and control problems. Results of research of aerodynamic characteristics for several UAVs are given.
