High Efficiency Controllable Pitch Propeller

海洋运输是一种高效的货物和人员运输方式，全球70%以上的贸易通过海上运输，形成了全球经济中的一个关键系统。虽然海上运输具有很高的能源效率，（每运输公斤货物排放的二氧化碳当量公斤数），这是一个很难消除温室气体排放的系统（GHG）。为了到2050年实现英国的净零排放和国际海事组织的50%，到2050年减排目标是一个具有挑战性和多方面的问题，需要新技术来提高能源效率，并以低温室气体替代品取代车载储能。该项目旨在解决这将是一个巨大的挑战，并在此过程中减少与传统燃料相关的温室气体排放，并使电池和氢气等替代性低能量密度存储解决方案更容易获得。Teignbridge已经开始了一项创新的、正在申请专利的、高效的可调螺距螺旋桨（CPP）解决方案的初步开发活动，与竞争的CPP技术相比，该解决方案将资本成本降低了24%。该项目将着手使这项技术更接近市场，从目前的概念原型验证阶段，到在HRV 1上进行海上演示，一个独特的推进系统测试船。同样的方式，使用多-通过确保原动机能够在接近最大效率的情况下操作，可以使用速度传动装置来提高陆地运输效率，在飞行器中，CPP在原动机和推进系统推力之间的有效传动装置中提供连续变化。先前的研究表明，与固定螺距螺旋桨（FPP）替代方案相比，CPP控制算法与具有高度可变占空比的船舶的精确匹配可以将效率提高8%至20%。进入这项技术的主要障碍是成本。该项目的一个关键目标是使该技术在更大的海上运输市场中发挥作用。Teignbridge在牛顿阿博特（英国）设计和制造螺旋桨已超过45年，是高品质螺旋桨和船尾齿轮设备值得信赖的合作伙伴。除了在推进设备的设计、制造和销售方面的内部专业知识外，Teignbridge的声誉和市场占有率最大限度地提高了快速占领市场的机会，从而对海运温室气体减排目标产生了影响。

Marine transport is a highly efficient method of transporting goods and people around the planet and with over 70% of global trade transported by sea, forms a critical system within the global economy. Whilst marine transport is highly energy efficient (kilograms of CO2-equivalent emitted per kilograms of goods moved), it is a difficult system from which to remove greenhouse gas emissions (GHG).Decarbonising marine transport in order to contribute to the UK's net zero by 2050 and the International Maritime Organisation's 50% reduction by 2050 targets is a challenging and multifaceted problem that requires new technology to improve energy efficiency and replace onboard energy storage with low GHG alternatives.This project seeks to address the energy efficiency aspect of the challenge and in so doing, to reduce GHG emissions associated with traditional fuels and make alternative, lower energy density storage solutions such as batteries and hydrogen more accessible. Teignbridge has undertaken initial development activity on an innovative, patent pending, high-efficiency controllable pitch propeller (CPP) solution which reduces capital cost by 24% compared to competing CPP technologies. This project will set out to bring this technology closer to market from its current, proof of concept prototyping stage through to at-sea demonstration of the technology on HRV1, a unique propulsion system test vessel.In the same way that using multi-speed gearing can be used to improve land transport efficiency by ensuring that the prime mover can be operated at close to maximum efficiency across the range of the loading conditions of the vehicle, CPPs provide continuous variation in effective gearing between the prime mover and propulsion system thrust. Previous studies have shown that accurate matching of CPP control algorithms to vessels with highly variable duty cycles can improve efficiency by between 8% to 20% when compared to fixed pitch propeller (FPP) alternatives. The principal barrier to entry for this technology is cost. A key target of this project will be to bring the technology within reach of a much larger portion of the marine transport market.Teignbridge has been designing and manufacturing propellers in Newton Abbot (UK) for over 45 years and is a trusted partner for high quality propellers and stern gear equipment. In addition to in-house expertise for the design, manufacture and sale of propulsion equipment, Teignbridge's reputation and market presence maximises the chance of rapid market uptake and therefore impact on the marine transport GHG emission reduction targets.
