Investigation of supersonic flow in wind tunnel T-38 by holographic interferometry method
Slavica Ristiæ
The holographic interferometer, designed, produced and tested for wind tunnel T-38 is described. New equipment is the base for holographic interferometry tests. Investigation of supersonic flow quality is the first in a series of experiments for testing of complex flow field around different models using holographic interferometry. In this article, the experiment and results of holographic interferometry application for analysis of flow quality in the test section are presented. The experimental results are compared with theoretical ones.
Key words: supersonic flow, wind tunnel, holographic interferometry, holographic interferometer.
