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 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 physical and 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 will be used in this project to use modelling 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. Successful implementation will also strengthen this important UK supply chain.

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。我们预计不会在不久的将来改变飞机的关键部位，例如机翼和机身，但在更换较少的飞行关键部位（例如支架，夹具，夹具，铰链，座椅扣和家具）方面具有真正的潜力。例如，为飞机生产1公斤的支架，需要在制造过程中输入10公斤的原材料。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。当我们像AM一样以逐层方式做出某些东西时，这些约束就会减少。根据我们与之交谈的公司的说法，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％。如果可以设计原子剂喷嘴，以将这一比例提高到50-60％的价格会大大降低，并且可用性会增加，从而使其对航空航天组件更加可行。自由粉金属（项目铅）和材料加工研究所（分包商）拥有超过30年的金属行业经验的员工，他们参与了重新设计基本的氧气制造，氧气喷嘴，使用物理和数学建模，并与喷嘴制造商紧密合作，以更高的速度相互融合，以更高的速度融合了稳定性，以使其能够融合了众多的效果。该项目将使用相同的人和技能来研究修改原子剂喷嘴的可行性。该项目将有助于实现政府的[清洁增长战略] [0]和[净零野心] [1]，以保护当前和后代的气候和环境，从而减少浪费免受航空航天组件的制造，飞机的轻巧加权和减少燃油消耗。成功的实施还将加强这一重要的英国供应链。 [0]：https：//www.gov.uk/government/publications/clean-growth-strategy [1]：https：//wwwww.gov.uk/government/news/uk-becomes/uk-becomes/uk-becomes-first-major-premonst-major-procon--pass-pass-net--net--net--net-remissions lard
