Abstract:With the increasing emphasis on performance, operational safety, energy saving and emission reduction, many new chal? lenges are being faced by the designers of gas turbine engines. In the past decade, the concept of intelligent gas turbines has received increasing attention due to their ability to balance performance and reliability. By extracting the benefits and challenges of intelligent gas turbine engines, a systematic review was conducted on the technical fields and requirements covered by intelligent gas turbine engines. By comparing the differences in typical mission profiles with aircraft engines and land-based gas turbines, intelligent requirements for marine gas turbine engines are proposed. Four key techniques are highlighted, including real-time inlet-distortion monitoring and distortion index evaluation, surge warning of compression system and blade vibration monitoring, adaptive thermal management of high-pressure turbine, and tip clearance measurement of high-temperature rotating components. The benefits of each key technology, the current research situa? tion at home and abroad, as well as the challenges to its implementation, are discussed in detail. However, the implementation of the above- mentioned key techniques requires continued work at two levels including the maturity and development of individual technology and the multi-disciplinary interrogation of technological benefits.
