One of the costlier items in current tidal turbine designs is the rotor blades. This project aims to assess the performance implications of the adoption of innovative, labour-saving, mechanized manufacturing processes for large diameter horizontal axis tidal turbines (>15 m) which could effect a substantial reduction in their cost. Current design practice involves consideration of the performance of tidal turbines in essentially quasi-steady operating conditions. The experience in the field, however, points to the fact that in energetic tidal locations the levels of in-stream turbulence are such as to impact negatively on their performance. The feasibility of combining lower cost manufacturing techniques for blades operating in turbulent tidal environments, with simpler designs which are tolerant of the transient operational conditions will be examined. The project seeks to establish what attendant modifications to an ideal datum design are involved in the streamlined construction and what are the performance implications of such modifications. The work will involve theoretical and experimental phases and will be carried out by a practised team of blade manufacturers and testing, design and analysis specialistsThe team in Cranfield composed of Dr Joao Amaral-Teixeira and Dr Florent Trarieux will undertake the assessment of the performance of a selection of proposed rotors. This project will be undertaken in close collaboration with Nick Barlow, Founder and Managing Director of Southampton based leading composite blade manufacturer, Designcraft Ltd. The project is articulated around four phases of review of current manufacturing techniques, novel blade profile selection, numerical assessment using Blade Element Momentum models and state-of-the-art tank tests in three different tanks of increasing size, flow actuation type and turbulence levels: Cranfield Towing Tank, Haslar Towing Tank and Boulogne-sur-mer Circulation Channel.

当前潮汐涡轮设计中的价格更高的物品之一是转子叶片。该项目旨在评估采用创新，劳动，机械化制造工艺的绩效含义，用于大直径水平轴向潮汐涡轮机（> 15 m），这可能会大大降低其成本。当前的设计实践涉及考虑潮汐涡轮机在基本上是准稳态的操作条件下的性能。然而，该领域的经验指出，在充满活力的潮汐位置中，流中湍流的水平是对其性能产生负面影响。将检查在动荡的潮汐环境中运行的叶片的较低成本制造技术的可行性，该设计具有更简单的设计，这些设计耐受瞬态操作条件。该项目旨在确定对理想基准设计的随之而来的修改涉及简化的结构，以及这种修改的性能含义是什么。这项工作将涉及理论和实验阶段，并将由一支由刀片制造商组成的实践团队以及由Joao Amaral-Teixeira博士和Florent Trarieux博士组成的Cranfield的测试，设计和分析专家将进行评估。选择拟议的转子。该项目将与位于南安普敦的创始人兼董事总经理尼克·巴洛（Nick Barlow）密切合作进行。元素动量模型和最先进的储罐测试在三种不同的储罐中，尺寸增加，流动驱动类型和湍流水平：Cranfield拖曳罐，Haslar Towing Tank和Boulogne-Sur-Sur-Mer-Mer循环通道。
