附加制造技术具有改善制造成本的潜力，并可能有助于实现高性能的航空航天结构。其中一个候选应用是风洞机翼模型。机翼隧道模型需要复杂的设计和精密的制造来进行精确的实验，这往往会增加制造成本。本文通过数值和实验相结合的方法，对附加制造的机翼模型的制造精度和气动弹性特性进行了评估。论证了这种机翼用于风洞试验的可行性。此外，通过与附加制造的高柔性机翼模型的风洞试验结果的比较，验证了先前研究建立的几何非线性气动弹性分析模型对静力计算的有效性。
Additive manufacturing technology has a potential to improve manufacturing costs and may help to achieve high-performance aerospace structures. One of the application candidates would be a wind tunnel wing model. A wing tunnel model requires sophisticated designs and precise fabrications for accurate experiments, which frequently increase manufacturing cost. In this paper, manufacturing accuracy and aeroelastic characteristics of an additively manufactured wing model are evaluated numerically and experimentally. The feasibility of such wings to use in wind tunnel tests is also demonstrated. In addition, a geometrically nonlinear aeroelastic analysis model, which have been developed in the previous study, is validated for static calculations by comparing with results of the wind tunnel test for the additively manufactured highly flexible wing model.
