摘要：

为解决航空发动机压力测量受感部研制过程中存在周期长、尺寸大和质量大的问题，采用3D打印技术开展航空发动机压力测量受感部制造方法研究。通过三维建模、切片离散、叠加打印、后期处理、精加工等流程制作压力受感部，并进行质量考核试验，通过考核后配装发动机使用。结果表明：采用3D打印技术制作压力受感部周期短、结构质量轻，受感部满足GJB150.16A—2009规定的振动耐久性试验考核要求，满足飞行试验装机使用条件，受感部可以达到预期使用寿命。形成一套基于3D打印技术的受感部设计和考核方法，未来3D打印技术在航空发动机受感部小型化、轻量化方面有广阔的应用前景。

Abstract: In view of the long cycle, large size and large weight of structure in the manufacture of traditional pressure sensing parts of aeroengine, the research on the application of 3D printing technology to the development of pressure sensing parts was carried out. The pressure sensing part was made through 3D modeling, slice discretization, superposition printing, post-processing, finishing and other processes, and the quality assessment test is carried out. After passing the assessment, the sensing part was installed and used in aeroengine. The research results shown that 3D printing technology can significantly shorten the development cycle and lighten structural weight. The sensing part manufactured by this technology can pass the vibration test durability test specified by GJB150.16A-2009, meet the service conditions of flight test, and can reach the expected service life. A set of design and assessment methods of pressure sensitive part on 3D printing technology was formed. In the future, 3D printing technology will have a broad application prospect in the miniaturization and lightweight of aeroengine sensing part.
