Experience in laser stereolithography and its application in manufacturing wind-tunnel aerodynamic models of various purposes

Abstract

In 2000-2001 the specialists of TsAGI and ILIT of the Russian Academy of Sciences developed the photopolymeric molds and tried up the technology of producing in these molds the wing tips of a complicated shape made of composite materials. During further development a complicated hybrid structure of a balance aerodynamic model was generated including primary metallic elements, contour-forming elements made of composites as well as separate contour- forming elements made directly from photopolymer. Prospects for extending this technology to dynamic and elastic models are considered.
