Изобретение относится к области экспериментальной аэродинамики. Новым в способе является определение аэродинамических характеристик асимметричного изделия при одновременном изменении угла атаки и крена модели в диапазоне 0 - 360o. Новым в устройстве является снабжение его боковой державкой и приводом перемещения модели в плоскости крена, выполнение консольной державки в виде вилки, на концах перьев-пилонов которой установлены подшипниковые узлы, а боковая державка выполнена в виде соединенного в диаметральной плоскости с обеих сторон с полуосями кольца, внутри которого установлена с возможностью вращения вокруг продольной оси модель изделия, при этом полуоси, выполненные в виде разрезанного на две части стержня, между которыми закреплены тензовесы, установлены в подшипниковых узлах консольной державки и закрыты обтекателями, причем привод перемещения модели в плоскости угла атаки установлен на одном пере-пилоне консольной державки и вал его соединен с одной из полуосей, а привод перемещения модели в плоскости крена установлен на другой полуоси между кольцом и тензовесами и вал его через передачу соединен с корпусом модели. Реализация заявленного способа определения на модели аэродинамических характеристик асимметричного изделия обеспечивает определение этих характеристик в условиях, приближенных к натурным, при любых пространственных углах атаки и крена модели изделия относительно трех координат X, Y и Z. По сравнению с прототипами заявленные технические решения сокращают время работы аэродинамической трубы и связанные с ней трудозатраты, так как не требуют остановки трубы и перестановки модели изделия.The invention relates to the field of experimental aerodynamics. New in the method is to determine the aerodynamic characteristics of an asymmetric product while changing the angle of attack and roll of the model in the range 0 - 360 o . New in the device is supplying it with a side holder and a drive for moving the model in the roll plane, making a cantilever holder in the form of a fork, bearing units are installed at the ends of the pylon feathers, and the side holder is made in the form of a ring connected in the diametrical plane on both sides, inside of which a model of the product is installed with the possibility of rotation around the longitudinal axis, while the semi-axes, made in the form of a rod cut into two parts, between which are affixed tensor, are installed in the bearing assemblies of the cantilever holder and are covered with fairings, and the drive for moving the model in the plane of the angle of attack is mounted on one pylon of the cantilever holder and its shaft is connected to one of the half shafts, and the drive for moving the model in the plane of the roll is mounted on the other half shaft between the ring and the tensile weights and its shaft through the transmission is connected to the model body. The implementation of the claimed method for determining the model of the aerodynamic characteristics of an asymmetric product provides a determination of these characteristics under conditions close to full-scale, at any spatial angles of attack and roll of the product model relative to the three coordinates X, Y and Z. Compared with prototypes, the claimed technical solutions reduce the time of work of the aerodynamic pipes and associated labor costs, since they do not require stopping the pipe and rearranging the product model.
