Nowadays, the development of wind tunnels for the study of various aerodynamic phenomena is actively developing. It is possible to generate a highly laminar flow only under the condition of structural stability of the construction parts of the wind tunnel under the action of sharp pressure drops. The aim of this research is to investigate the deformation and displacement of the structural parts of the developed wind tunnel capacity of 55 kW depending on the velocity of the generated airflow. To estimate the amount of deformation and mutual displacement of the structural elements of the wind tunnel depending on the airflow velocity, we used the ARAMIS optical system.
