Abstract:

Fluctuations of parameters of the laser beam, extending above a surface of a flat wing model blown by a supersonic air flow, are experimentally researched. Researches are executed in ITAM SB RAS on altitude tunnel АТ-316, in which a flow of a speed of 600 m/s is formed in the closed tunnel of the square section. Dispersions and spectra of fluctuations of intensity and corners of arrival of the laser beams, extending above the model at various angles of attack of a wing, are analyzed. Estimations of parameters of the turbulence between the wing and the shock wave are presented.

Keywords:

fluctuations, the spectra, a probing beam, a supersonic stream
