Additive manufacturing (AM) of aerospace components create opportunities for lighter weight and higher performance parts which could significantly reduce both manufacturing waste (lower buy-to-fly ratio) and the weight of an aircraft. This will result in fuel savings, operational costs and decrease carbon emissions, thereby benefiting our environment.We do not anticipate a change to the crucial parts of the aircraft, such as the wings and fuselage in the near future but there is real potential in the replacement of less flight-critical parts, such as brackets, clamps, hinges, seat buckles and furnishings.To produce a 1kg bracket for an airplane, for example, requires 10kg of raw material input into the manufacturing process. From an engineering design perspective, that final bracket may still contain much more metal than is required for the application. 3D printing, on the other hand, requires far less raw material inputs and can further produce parts that minimise weight through better lattice type design. Current sub-optimal designs are due to the limits of conventional manufacturing. When we make something in layer-by-layer fashion as in AM, those constraints diminish.One of the biggest barriers to the aerospace industry fully adopting additive manufacturing, according to companies we have spoken to, is the cost and availability of the powder metal. The 15-45 micron fraction used in AM is only approximately 40% of the production. If the atomiser nozzle can be designed to increase this fraction to 50-60% the price significantly reduces and availability increases, making it more viable for aerospace components.Liberty Powder Metals (project lead) and the Materials Processing Institute (subcontractor) have employees with over 30 years experience in the metals industry who have been involved in redesigning basic oxygen steelmaking, oxygen lance nozzles, using audiometry, physical, mathematical modelling and working closely with the nozzle manufacturer to successfully improve refining of the steel bath and to maximise the amount of scrap melting to make the process more efficient and economically viable. The same people and skills together with the University of Leeds will be used in this project to use modelling and audiometry to investigate the feasibility of modifying the atomiser nozzle.This project will help deliver on the government's [Clean Growth Strategy][0] and [net zero ambition][1] to protect the climate and environment for current and future generations by reducing waste from the manufacturing of aerospace components, light weighting of aircraft and reducing fuel consumption.[0]: https://www.gov.uk/government/publications/clean-growth-strategy[1]: https://www.gov.uk/government/news/uk-becomes-first-major-economy-to-pass-net-zero-emissions-law

航空航天组件的增材制造（AM）为更轻的重量和更高的性能零件创造了机会，这可能会大大减少制造浪费（较低的购买比率）和飞机的重量。这将导致节省燃料，运营成本并减少碳排放，从而使我们的环境受益。我们预计在不久的将来会改变飞机的关键部分，例如机翼和机身，但要替换较小的飞行零件，例如较小的飞行零件，例如，架子，架子，架子，架子的架子和装备的架子。在制造过程中需要10公斤的原材料输入。从工程设计的角度来看，该最终支架可能仍然包含比应用程序所需的金属要多得多。另一方面，3D打印所需的原材料输入要少得多，并且可以通过更好的晶格类型设计产生最大程度地减少重量的零件。当前的次级设计是由于常规制造的限制。根据我们与之交谈的公司的说法，当我们以逐层方式制作某种方式时，这些限制会减少。航空航天行业完全采用增材制造的最大障碍之一是粉末金属的成本和可用性。 AM中使用的15-45微米馏分仅约占生产的40％。 If the atomiser nozzle can be designed to increase this fraction to 50-60% the price significantly reduces and availability increases, making it more viable for aerospace components.Liberty Powder Metals (project lead) and the Materials Processing Institute (subcontractor) have employees with over 30 years experience in the metals industry who have been involved in redesigning basic oxygen steelmaking, oxygen lance nozzles, using audiometry, physical,数学建模并与喷嘴制造商紧密合作，以成功改善钢浴的精炼，并最大程度地提高废料融化的量，以使过程更有效且在经济上可行。该项目将使用相同的人和技能以及利兹大学使用模型和听力计量法来调查修改原子剂喷嘴的可行性。该项目将有助于对政府的[清洁增长策略] [0]和[净零雄心勃勃]和[1] [1] [1] [1] [1]来保护当前和未来的燃料的气候和未来的燃料，以减少空间和未来的燃料，并降低飞机的范围，以减少对空间的构建，并将其稳定供应量，以减少空间的稳定量。消费。[0]：https：//www.gov.uk/government/publications/clean-growth-strategy [1]：https：//wwww.gov.uk/government/news/news/uk-becomes/uk-becomes-first-major-ecormes-first-major-economy-to-pass-net-net-net-net--zere----------zere dard
