Experimental study on the optical propagation effect of the flowfield surrounding the optical headcover in supersonic wind tunnel
摘要
Abstract
For measuring optical propagation effects of a head-cover's flow fields,a simulated test method is introduced in a continuous supersonic wind tunnel (Ma=3).With the analysis of vibration measurement and isolation,specialized test equipment is developed.Finally,optical propagation effects are measured both with Hartmann wavefront sensor and shearing interferometer.In the pilot study,with different combinations of the experimental apparatus,a large number of tests have been done,from which to study the effectiveness of the experimental apparatus and the repeatability of the data.And the data analysis focus on the PV and RMS of the probe beam.With the test result,we can conclude that the wind guiding deflector is able to reduce the interference of boundary layer generated by the wall of wind tunnels,and the experimental equipment and method we developed are quite qualified for optical propagation effects measurement in continuous wind tunnels.关键词
