在这个以“更好、更快、更便宜”为生存准则的时代，必须采用新技术来尝试实现这些公理。本着这种精神，我们开展了一项研究，以确定使用快速原型 (RP) 方法构建的模型是否适用于亚音速、跨音速、风洞测试。这项研究的目的是确定快速原型材料和工艺的发展水平是否足以构建模型，以及这些模型是否满足亚音速、跨音速、测试的结构要求，同时仍然具有产生准确的空气动力学数据所需的高保真度。这项初步研究的结果表明，从 RP 模型获得的空气动力学数据库与从机加工铝对应件获得的数据表现出良好的一致性。
In a time when "better, faster, cheaper" are the words to live by, new technologies must be employed to try and live up to these axioms. In this spirit, a study has been undertaken to determine the suitability of models constructed using rapid prototyping (RP) methods for use in subsonic, transonic, wind tunnel testing. This study was conducted to determine if the level of development in rapid prototyping materials and processes is adequate for constructing models, and if these models meet the structural requirements of subsonic, transonic, testing while still having the high fidelity required to produce accurate aerodynamic data. The findings from this initial study indicated that the aerodynamic database obtained from RP models showed good agreement with data obtained from the machined Aluminum counterpart.
