Abstract : Object of the invention: Aerodynamic scales (windtunnel balance) for measuring small loads including a 'floating' frame suspended on a lever unit, equilibrized by the forces of the electromagnetic interaction of movable and fixed coils, which has the distinguishing feature that for the purpose of assuring high sensitivity and excluding error from the influence of the weight of the model and the movable elements, they are designed in the form of a statically balanced system of lever elements fastened on vertically arranged thread suspensions and provided with a set of coils equalizing the moments formed on the 'floating' frame from the forces of the measuring element and excluding the breaking of the threads of the suspension.
