DEVICE FOR CHANGING POSITION OF MODEL IN WORKING PART OF AERODYNAMIC PIPE Russian patent published in 2019 - IPC G01M9/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to experimental aerodynamics, particularly to devices for changing position of tested model in working part of aerodynamic pipe. Device comprises attachment assembly holder for installation of model and three pairs of posts, pivotally connected by one end to unit attachment holder in two sections, spaced along its length, and by the other end, by means of three pairs of hinges, with three carriages arranged on two longitudinal guides installed in the working part with the possibility of movement by means of independent drives. One of the guides is pivotally mounted about its own longitudinal axis, and the other one is rigidly connected to the first one; it is equipped with an independent rotation drive and a device for fixation of the device in the required angular positions around the axis of the first guide.

EFFECT: higher rigidity and faster operation of the device for setting the position of the model in the working part of the wind tunnel.
