Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The present invention is a kind of three-dimensional ice shape detector that is applicable to carrying out the model icing test in the icing ground test of aircraft parts, and it comprises externally purchased devices (laser, CCD camera, stepper motor, steering gear, etc.), and Mobile sub-platform and rotating sub-platform for installing external components.

[0046]The laser in the externally purchased device is used to provide a colored line laser beam (red line laser can be selected), and the colored line laser beam is irradiated on the icing surface of the icing part to form a light bar curve; When the complex shape of the ice is on, due to the modulation of the shape of the ice, the laser is no longer a straight line, but becomes a curve. The degree of curvature is related to the shape of the ice. Different shapes of the ice will result in differe...

Abstract

The invention discloses a three-dimensional ice form detection instrument, which comprises externally purchase components such as a laser, a CCD camera, a step motor, a steering engine and the like. The three-dimensional ice form detection instrument also comprises a movement sub platform and a rotation sub platform, wherein the movement sub platform and the rotation sub platform are used for installing the externally purchase components, the movement sub platform is used for supporting the rotation sub platform to make the rotation sub platform move in the horizontal direction, and two guide rails arranged on the rotation sub platform can make the laser and the CCD camera be regulated to an angle satisfying the collection. The three-dimensional ice form detection instrument designed by the invention is based on the visual ice forms, can intuitively display the icing forms in an image mode, provides the visual technical solution scheme for researchers to accurately identify the three-dimensional ice forms and to obtain the dimension data of the ice forms, has important significance and practical value of the later stage study of influence of icing on the aircraft aerodynamic performance, and provides test verification detection measures for the three-dimensional ice forms obtained through calculation.

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...
