AERODYNAMIC STAND FOR INVESTIGATION OF THE FEATURES OF FLOW AROUND A MULTI-ENGINE POWER PLANT DURING AIRCRAFT MOTION Russian patent published in 2022 - IPC G01M9/08 

FIELD: aerodynamic testing.

SUBSTANCE: invention relates to the field of aerodynamic testing of air intakes of a multi-engine power plant of an aircraft. The aerodynamic stand contains a frame consisting of vertical and horizontal frames connected to each other in mutually perpendicular planes, models of the first and second engine nacelles with air intakes equipped with a device for sucking air through them, mounted on a vertical frame, and a storage device installed in the outlet part of the engine nacelles. Each of the engine nacelles is equipped with mechanisms for transverse and vertical reciprocating motion with the ability to move in a vertical plane with fixation of a given angle and in a longitudinal axis relative to each other. There is a mechanism for creating an external air flow with the ability to control its direction, speed and degree of unevenness, as well as a means of photo / video recording. Under the models of the first and second engine nacelles, a block for simulating the movement of the airfield surface is installed on a horizontal frame, equipped with a block for laying out foreign objects.

EFFECT: invention is aimed at increasing the functionality of the test bench during flow studies.
