Abstract

The safety of an aircraft depends on the wing flow process, therefore, the study of air flow in various flight conditions is one of the most important parts of the design and operation of an aircraft. A hydrodynamic tube is one of the most effective means for studying the processes of aircraft flow in aerodynamics. It allows you to simulate special conditions and study flow characteristics that cannot be studied in real flight. Standard flow visualization methods, such as colored jets or fine particles, allow us to obtain qualitative data on the flow behavior. But it is more important to have quantitative flow characteristics that allow you to predict the development of the process and develop recommendations on flight safety measures. In this paper, the possibility of conducting non-contact three-dimensional measurements in hydrodynamic tubes by photogrammetric methods is considered. The article presents the development of a system of remote three-dimensional measurements based on images to obtain an accurate three-dimensional visualization of the flow used to quantify the parameters of the flow of aerodynamic elements in a hydrodynamic tube. The results of experimental studies on the calibration of a three-dimensional measurement system for the case of shooting an object through two boundaries of optical media are presented. The developed method of calibration of a photogrammetric system for three-dimensional measurements in an aqueous medium has demonstrated its applicability to the problem of spatial analysis of flow flows in a hydrodynamic tube.
