Performance Improvement and Material Optimization of Aviation Power Systems

Abstract

With the continuous improvement of aviation industry performance requirements, the increasing pressure to reduce greenhouse gas emissions and the high maintenance costs, traditional engines can no longer meet the development requirements of modern aviation in terms of high performance, high temperature resistance and low cost. Regarding the core issue of "how to improve the overall performance of engines/generators”, this paper focuses on optimizing the aerodynamic/thermal design of aircraft engine turbine blades, applying advanced high-temperature materials and additive manufacturing (AM) technology to achieve lightweight and high-temperature resistance, and introducing an artificial intelligence (AI)-driven digital twin platform to perform multi-scale simulation and remaining life prediction of the entire material life cycle to support on-demand maintenance and rapid iterative design. It systematically explores ways to improve engine performance and reduce maintenance and operating costs. This article can achieve specific power improvement, weight reduction and significant reduction in maintenance costs under the premise of ensuring the reliability of aircraft engines, laying the foundation for the efficiency, lightweight and intelligence of the next generation of aviation electric-power systems.
