The paper presents a software module for flexible configuration of a measuring system implements phase triangulation methods to measure three-dimensional profile of objects in aerodynamic experimental stands. To adjust and optimize a wide range of parameters of the measuring system, a universal solution has been implemented, that aimed to control of the operation of phase triangulation algorithms and binary Gray codes. To estimate the measurement error, an automated algorithm is implemented based on a statistical analysis of the distribution of the coordinates of the points of the measured surface.

The laser-Doppler anemometry method was developed for experimental studies on control of turning-and-diverging flow have been carried out; detailed diagnostics of averaged and turbulent characteristics have been made. Numerical modeling and comparison with experimental data based on known up-to-date turbulence models have been performed; comparative analysis of models has been done. The findings may be useful for determination of applicability limits of turbulence models.

The paper presents a method for calibration of a three-dimensional geometry measurement system based on the phase triangulation for measurements in the conditions of limited volume with optical signals refraction. The calibration algorithm implements calibration procedures directly in the measurement volume in the presence of all the limiting objects that cause optical signals refraction. The method is universal for various conditions of limiting volume with optical signals refraction. The developed calibration method was tested in the case the limiting volume in the form of a plexiglass tube with the transverse size of 200 mm ´ 200 mm and the wall thickness of 20 mm and the measurement volume of 100 mm ´ 100 mm ´ 100 mm. The accuracy of 12 microns was achieved in the measurement of flat object three-dimensional geometry.
