Device for Varying the Angle of Attack of an Aircraft Model,
Abstract
A description is given of a device to vary the angle of attack of an aircraft model. It was tested on an aerodynamic installation consisting of an electric motor with a reduction gear hinged to a guide shaft mounted on a cantilever-type rod which interacted with an aerodynamic balance drive which, in turn, was equipped with a balancing load, a system of driving arms, bevel gears and a bracket. To increase test accuracy, the guide shaft is attached kinematically to the model bracket in such a way that the given angle of attack for the model is equal to the angle formed by the axes of the aerodynamic balance drive shaft and the model bracket, whose point of intersection is aligned with the center of gravity of the test model and is located on the axis of the aerodynamic balance drive.
