TAILORED COMPOSITES TUNED DEFORMATION RESPONSE

项目摘要

The main motivator for the proposed research is performance improvement of energy capture or hydrodynamic efficiency of propulsion systems. In particular, the application requirements of passively adaptive underwater tidal turbine blades and marine propellers. However, the investigators believe that application of passively adaptive composites structures could extend to include passively adaptive race car aerodynamics, aircraft control surfaces, surface ship and underwater vehicle control surfaces, and wind turbines. In order to achieve this goal it is proposed to employ composite materials with their inherent ability to create a coupled response to in-service loads. Design of such a structure which is tuned to a dynamic load environment will result in improved efficiency of the two main applications of this research, energy capture devices and marine propulsors.The aim of the proposed research is to challenge the existing design philosophy from one whereby a tailored passively adaptive composites is designed to mimic a conventional isotropic structure into a paradigm that allows the ability to tune a geometry and it's internal architecture to deform in a known and controlled manner as the load regime changes. Such an approach requires fundamental research into the modelling of interwoven, 3D fibre structures and novel approaches to design of the internal architecture that can identify fibre stacking/weaving strategies that give tuned deformations across multiple loading/operational conditions. To develop this paradigm shift in structural performance we will explore how lifting surfaces, be they control surfaces, propulsors or turbines are designed using such smart materials. The main focus will be the maritime sector where there has been a much slower take-up in such technology but where the potential benefits are large (see impact plan). To the authors knowledge this has not been conducted anywhere before and is therefore a challenging and exciting programme.

拟议研究的主要动机是推进系统的能量捕获或流体动力效率的绩效。特别是，被动自适应水下潮汐涡轮刀片和海洋螺旋桨的应用要求。但是，调查人员认为，被动自适应复合材料结构的应用可能会扩展到包括被动自适应赛车空气动力学，飞机控制面，地面船和水下车辆控制表面以及风力涡轮机。为了实现这一目标，建议采用具有固有能力的复合材料，以对服务载荷产生耦合响应。这种结构的设计被调用到动态负载环境将提高这项研究的两个主要应用，能量捕获设备和海洋推进器。拟议的研究的目的是从一种研究的目的挑战现有的设计理念，从一个量身定制的被动自适应复合材料中，该理念旨在模仿传统的同位素结构，以使其在范围内构建型号，以使其允许构建型号，以构建型号，以构建轨迹，以构建型号，以构建型号，以构建型号，以构建型号，以构建型号，以构建型号，并构建型号的构造效果。随着负载制度的变化，受控方式。这样的方法需要基础研究对内部体系结构的编织，3D纤维结构的建模和新颖的方法，这些方法可以识别纤维堆叠/织造策略，这些策略可在多个负载/操作条件下进行调整的变形。为了开发这种结构性能的范式转变，我们将探讨如何使用此类智能材料来设计表面，推进器或涡轮机。主要重点将是海事领域，在这种技术中采用速度较慢，但潜在的好处很大（请参阅影响计划）。据作者知道，这从未在任何地方进行，因此是一个充满挑战和令人兴奋的计划。
