FIELD: experimental aerodynamics.
SUBSTANCE: invention relates to experimental aerodynamics of aircraft and can be used in static and dynamic tests of models of aircrafts in wind tunnels. Device includes a platform with a lower base, on which there are electric drives, an electric drive control unit, an upper movable platform base, a frame, one end of which is fixed on the platform upper base, and other end is connected to horizontal shaft together with intramodel assembly and dynamometer, device for creation of harmonic oscillations of model in roll and yaw is installed on horizontal shaft. Device for generation of harmonic oscillations of the model by roll and yaw is made in the form of an electric drive installed by means of a bracket on the electric drive frame and the rocker, which is connected to the shaker of the horizontal shaft.
EFFECT: high accuracy of measuring lateral non-linear non-stationary aerodynamic characteristics with oscillations of the model by yaw or roll in a wide range of amplitude oscillations and frequencies.
