Composite rotor flex beam flapping optimization

加拿大的航空航天工业是仅次于美国和欧洲共同体的世界第三大航空航天工业。为了保持或改善其在这个竞争激烈的市场中的地位，加拿大必须保持 与最新技术同步。随之而来的是不断要求升级分析和设计程序，以开发新的材料和制造工艺。 这项合作研究与发展资助的总体目标是：对复合材料张力梁的破坏机制有更好的科学认识，开发能够在参数设计空间中预测结构性能的模拟软件，确定改进的结构配置以及可行的材料和制造工艺，建造和测试改进的构型，并量化直升机工业提供的基线设计的改进。 因此，拟议的CRD将侧重于加速与直升机主旋翼轮毂应用典型复合材料张力梁分析和设计相关的科学和技术知识。采用先进材料和制造工艺的适当工程结构有望提供更高质量的复合材料部件，其疲劳性能优于目前在直升机行业中使用的部件。所开发的技术和程序将是确定竞争优势的一个关键因素，并将提高加拿大竞标全球航空航天未来主要平台的能力。这对加拿大未来的经济至关重要。

The Canadian aerospace industry is the third largest in the world behind the USA and the European Community. In order to retain or improve its position in this competitive marketplace Canada must keep abreast of the latest technologies. Contingent with this comes a constant requirement to upgrade analysis and design procedures so as to exploit new materials and manufacturing processes. The overall objectives of this Collaborative Research and Development Grant (CRD) are to develop a better scientific understanding of the failure mechanisms of composite tension beams, to develop simulation software capable of predicting structural performance in a parametric design space, to identify improved structural configurations and capable materials and manufacturing processes, to build and test improved configurations and quantify the improvement over the baseline designs furnished by the helicopter industry. The proposed CRD will therefore focus on the acceleration of scientific and technical know-how relating to the analysis and design of composite tension beams typical of helicopter main rotor hub applications. Properly engineered structures employing advanced materials and manufacturing processes promise to deliver composite components of higher quality, with improved fatigue performance over those currently employed in the helicopter industry. The technology and procedures developed will be a key factor in defining competitive advantage and an enhancement to Canada's ability to bid on worldwide aerospace future major platforms. This will be crucial to the future Canadian economy.
