Description

technical field [0001] The invention relates to a detection device for identifying ice shape, more particularly, a three-dimensional ice shape detector suitable for model icing tests in ground tests of aircraft component icing. Background technique [0002] Aircraft surface icing detection technology is mainly to install icing detectors on the positions where the aircraft surface is prone to icing, to determine whether the surface of the aircraft is icing and the thickness of the icing during flight, and to provide icing signals, but does not include the detection of icing. The measurement of ice shape, however, the ice shape on the surface of aircraft components has an important impact on its aerodynamic, stability and other characteristics. [0003] Prediction of icing ice shape on the surface of aircraft components is an important content of aircraft icing research. At present, the three-dimensional icing on the surface of aircraft components is often obtained by numeric...

Problems solved by technology

[0004] At present, in the icing ground test of aircraft components, the cutting method is often used to obtain the two-dimensional contour shape and size data of the ice shape. However, it is difficult to obtain high-precision ice shape and size data because the ice is easily damaged during cutting. , and the cutting method cannot obtain the three-dimensional ice shape data features
