High-efficient abrasive waterjet machining of complex curved surfaces

该项目旨在开发一种磨料水射流加工技术，有望将复杂曲面结构的制造效率提高4倍，如涡轮机械和航空发动机中使用的整体叶轮和叶盘。它还将探索与超高速磨料水射流的能量耗散过程和由大量颗粒云撞击的曲面生成过程相关的科学。预期的结果将打破技术障碍，使整体式叶轮和叶盘在飞机上的广泛使用完全可能显著提高燃油效率。预计经济效益、社会效益和环境效益都将是巨大的。

This project aims to develop an abrasive waterjet process technology that is expected to increase the manufacturing efficiency by 4 times for complex curved surface structures such as the integral impellers and blisks used in turbine machines and aeroengines. It will also explore the science associated with the energy dissipation process for ultrahigh velocity abrasive waterjets and the curved surface generation process by the impact of a cloud of numerous particles. The intended outcome will break a technological barrier and make it entirely possible for the wide use of integral impellers and blisks in airplanes to significantly increase fuel efficiency. The economic, social and environmental benefit is expected to be enormous.
