Application of 3D ice shape laser measurement technology in icing wind tunnel
The principle of measuring 3D structure for ice accretion in icing wind tunnel with ROMER measuring instrument was introduced,and a fast reconstruction method for model with ice shape was proposed.Typical rime ice,rough ice and horned ice were obtained by wind tunnel test.The 3D morphology of ice accretion was measured by ROMER instrument,and the 3D data of ice accretion on the surface of the model were obtained.The results showed that 3D results of rime ice were highly consistent with the actual ice shape,and the detailed characteristics of ice accumulation can be accurately measured.3D scanning technology can measure the rough ice results which can not be obtained by hot knife method.Compared with the ice trajectory of the shorn ice obtained by the hot knife method,the ice trajectory of the 3D ice shape in the same section had the same icing range and icing level,with the average thickness deviation of ice up to 2.5 mm.
