FIELD: dynamic testing.

SUBSTANCE: invention relates to a stand for dynamic testing of wheel propellers. The stand contains a support device in the form of a pedestal with a vertical axis on a rigid support and a rotary-holding propulsion device kinematically connected to it. The curbstone is a thick-walled tube, on the upper end of which a removable platform rotatable around the curbstone axis is mounted, on which a holding device in the form of a four-hinged antiparallelogram is mounted that is rotatable in the curbstone axis plane. On the cantilever part of the antiparallelogram connecting rod there is a dovetail guide for fixing the propeller. On the rigid support of the pedestal, a removable annular running track of the propeller is attached, which can be in the form of a spiral staircase or in the form of a wave with an amplitude increasing towards the periphery.

EFFECT: expanding the functionality of the stand.
