Omega Dot is an engineering consultancy specialising in turbomachinery specific to air foil bearings (AFB). An application of our technology is within the hydrogen fuel cell system for electric vehicles (EVs). Turbomachinery can be used within the fuel cell system to boost efficiency, offer an oil-free operation that runs near frictionless and has low noise levels. Although it can run near frictionless, the AFB system has issues during start-stop cycles where there is contact between the bearing and the shaft. This contact occurs at low speeds and causes frictional wear which weakens the overall system. To date, Omega Dot can validate their AFBs to 5,000 start-stop cycles but for production within the EV market and automotive industry, it is imperative to validate them to 250,000 start-stop cycles.This project will detail the analysis of the PTFE coating used in Omega Dot's AFB for surface distress for when this occurs and how deep the impact on a material level is to the overall system. We have partnered with NPL and ASTUTE to answer this question. It is imperative to provide practical evidence of our bearings' cyclic life as the market has emphasised this importance.Omega Dot and their A4i partners are hoping to bring together their expertise and facilities to tackle the challenge described in this application which Omega Dot is not able to solve without NPL and ASTUTE. The results from this project may identify strengths and weaknesses within the current AFB configurations and how they can be improved for production. NPL and ASTUTE will help Omega Dot to interpret the results from the studies. The outcomes from this project will push Omega Dot into commercialisation of their AFBs through lifecycle validation and allow Omega Dot to invest in their production and manufacturing capabilities. This will help to secure larger client orders which will give us sustained economic growth and boost the hydrogen fuel cell system supply chain.

Omega Dot是一家工程咨询公司，专门研究特定于空气箔轴承（AFB）的涡轮机械。我们技术的应用是在电动汽车（EV）的氢燃料电池系统中。可以在燃料电池系统中使用涡轮机械，以提高效率，提供无油的操作，该操作在无摩擦接近且具有低噪声水平。尽管它可以接近摩擦，但AFB系统在轴承和轴之间接触的开始周期中存在问题。这种接触以低速发生，并导致摩擦磨损，从而削弱了整个系统。迄今为止，Omega Dot可以将其AFB验证为5,000个起动周期，但对于在电动汽车市场和汽车行业内的生产，必须验证他们至250,000个起动车站循环。此项目将详细介绍对Omega Dot afb中使用的PTFE涂层的分析，以使其表面困扰，以使其对何时发生对物质的影响以及对整体系统的影响，从而对整体系统进行了影响。我们已经与NPL合作，敏锐地回答了这个问题。必须提供实用证据表明我们的轴承的环循环生活，因为市场强调了这一重要性。欧洲裔DOT及其A4I合作伙伴希望将他们的专业知识和设施汇集在一起​​，以应对此应用程序所描述的挑战，而欧米茄点无法在没有NPL和Astute的情况下解决该应用程序。该项目的结果可能会确定当前AFB配置内的优势和劣势以及如何改善生产。 NPL和ATTUTE将帮助Omega Dot解释研究的结果。该项目的结果将通过生命周期验证将Omega Dot推向其AFB的商业化，并允许Omega Dot投资于其生产和制造能力。这将有助于确保更大的客户订单，从而为我们提供持续的经济增长并增强氢燃料电池系统供应链。
