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.

加拿大航空航天业位居世界第三，仅次于美国和欧盟。为了保持或提高其在这个竞争激烈的市场中的地位，加拿大必须保持 及时了解最新技术。随之而来的是对升级分析和设计程序的持续要求，以便开发新材料和制造工艺。 该合作研究与开发补助金（CRD）的总体目标是更好地科学理解复合材料张力梁的失效机制，开发能够在参数化设计空间中预测结构性能的模拟软件，识别改进的结构配置和强大的材料和制造工艺，构建和测试改进的配置，并量化直升机行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的复合张力梁的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正确设计的结构有望提供更高质量的复合材料部件，与目前直升机行业使用的部件相比，其疲劳性能得到改善。所开发的技术和程序将成为确定竞争优势和增强加拿大竞标全球航空航天未来主要平台的能力的关键因素。这对于加拿大未来的经济至关重要。
