An Investigation on Manufacture Method of High-speed Wind-tunnel Test Models Based on Stereo-Lithography Technique

摘要

The paper presents a novel manufacture method of high-speed wind-tunnel test models with internal metal frame and surface photopolymer resin based on Stereo-Lithography (SL) technique. Internal metal frame structure was designed to be of regular configurations that can be conveniently fabricated by conventionally mechanical manufacturing methods. Outer resin components were designed to meet configuration fidelity and surface quality, which were fabricated by SL facilities. Combination of aerodynamics and structure was utilized to accomplish structural design, strength and stiffness calibration and vibration analysis. It is validated that the manufacture method is suitable to construct the high-speed wind-tunnel models by some typical wind-tunnel models, especially for test models with complex structure.
