Development of additive layer manufacturing technology for aeroengine compact air oil heat exchanger

热交换器在许多工程领域都是不可或缺的。特别是在航空航天应用中，热交换器对于确保航空发动机的正常运行至关重要。增材制造（AM）能够通过拓扑优化设计创建复杂的结构，并可用于提高热交换器（HX）的性能，减少浪费和重量，从而减少航空航天领域的环境影响。结合拓扑优化技术，了解敏捷制造对HX产品可靠性的影响，可以为下一代航空发动机HX的开发提供技术支持。此外，用于空气-油HX的典型材料是铝合金，这些材料的AM仍然是一个挑战。因此，分析和开发铝合金的层制造技术（如AM）是能够创造无泄漏、高性能HX（以薄特征为特征）的基础。最后，通过拓扑优化工具，可以创建一个新的复杂HX设计，并通过AM生产，以更小的体积和更低的重量增加热性能。

Heat exchangers are indispensable in several engineering areas. In particular, in aerospace applications, heat exchangers are essential to ensure the proper functioning of an aero-engine. Additive Manufacturing (AM) has the ability to create complex structures designed through topology optimisation and can be used to improve the performance of Heat Exchangers (HXs) reducing the waste and weight and therefore the environmental impact of the aerospace field. Combining the topology optimisation technique and understanding the influence of AM on the reliability of HXs production we can develop the technology for the HXs of the future generation of aero-engine. Furthermore, the typical material used for the air-to-oil HXs is Aluminium alloy and the AM of these materials is still a challenge. Therefore, the analysis and development of layer manufacturing techniques such as AM, for the Al alloys is fundamental to be able to create a leak-free, high-performance HX characterised by thin features. Finally, through the Topology Optimation tools a new complex HX design can be created and produced by AM and incrementing the thermal performances in a smaller volume and low weight.
