ICE SIMULATOR MANUFACTURING METHOD Russian patent published in 2012 - IPC G01M9/08 

FIELD: test equipment.

SUBSTANCE: invention refers to aerodynamics and can be used at investigations of characteristics of aerodynamic models (AM) of transport vehicles. The method consists in the fact that on the leading edge of the object, for example of a wing, there arranged is a collar that is made from photopolymer using quick prototyping method. Besides, as per mathematical wing model there created are internal outlines of mathematical model of collar - ice simulator; then, as per the specified frame sections simulating ice formation there created are external outlines of collar - ice simulator in the form of double curved surface. Then, mathematical model of ice simulator is divided into parts; for each part there created is mathematical model of connection element - lock representing shaped elements of pin-slot type, as well as mathematical model of support elements of jig system, the dimensions of which define the geometry of ice simulator in the space on the jig plate. Based on the created mathematical models of ice simulator parts, locks and support elements there made on a stereolithograph are separate parts of ice simulator and support components, which are oriented vertically in the stereolithograph. Ice simulator is assembled by means of the jig plate on which ice simulator parts are installed in turn on support elements of the jig system; at that, liquid photopolymer is pre-applied to locks, parts are connected and photopolymerisation of liquid photopolymer in locks is performed by means of UV lamp. Ice simulator removed from the jig is cleaned from photopolymer residues.

EFFECT: improving the manufacturing accuracy of ice simulator and shortening its manufacturing period.
