FIELD: aircraft engineering.
SUBSTANCE: invention relates to devices designed for aerodynamic testing, and can be used in aircraft building. Stand includes a dynamometer platform, designed to fix the object, installed by means of at least four variable hardness plates on a fixed support platform with the possibility of moving the dynamometer platform along three orthogonal axes, each plate being formed with a flexible portion, coupled with hard parts, and is equipped with a load measuring element, and is characterized in that it comprises a sensor, registering the longitudinal movements of the dynamometer platform and designed to measure the longitudinal load, and the load measuring element is made in the form of two pairs of identical strain gage sensors, intended for measuring vertical and lateral loads, installed on at least one flexible section of each plate at the same level relative to the fixed support platform, sensors of each pair are mounted on opposite wide sides of the plate, wherein the vertical symmetry axes of the sensing elements of the sensors of one pair are oriented along the vertical axis of symmetry of the wide side of the plate, and the vertical axis of symmetry of the sensing elements of the sensors of the other pair are parallel to it, sensors are connected in one arm of separate measuring bridges, and the sensors of each pair are connected in series.
EFFECT: technical result consists in the possibility of increasing the accuracy of simulating the conditions of a supersonic flight of an aircraft.
