Abstract

The distributed propulsion system has a significant potential for reducing the fuel consumption, noise and pollution emissions for the next-generation aircraft and become a current hot research topic. As the core component of the distributed propulsion system, the boundary layer ingestion fan has been continuously operating under the distorted inflow conditions, which largely degrades the aerodynamic performance of the fan itself. In turn, the degradation of the BLI fan performance will have a severe impact on the overall aerodynamic benefits achievement of the aircraft. This paper has conducted a systematic review of the boundary layer ingestion fan. Firstly, the aerodynamic benefits of BLI propulsion system has been overviewed. Then, different types of BLI fan based propulsion configurations have been introduced and the distinguished features of the distorted inflows for each configuration are analyzed in detail. Thirdly, the fan aerodynamic responses to the BLI distorted inflow are given and the influences of the BLI inflow distortion on the fan aerodynamic performances and internal flow fields are fully investigated. Subsequently, the potential performance evaluation methods, mainly the low-order computational approaches, used in the preliminary design stage of the fan have been comprehensively overviewed. Finally, the research works concerning the attempts for the fan/compressor design under non-uniform inflow condition are reviewed and some perspectives of the distortion-tolerant BLI fan design in the future have also been presented. The motivation of this work is to provide some useful guidelines for the upcoming research works concerning the BLI fan based propulsion systems.
边界层摄取(BLI)风扇的系统综述:现状与未来展望
分布式推进系统在降低下一代飞机的油耗、噪声和污染排放方面具有巨大的潜力,成为当前的研究热点。边界层进气风扇作为分布式推进系统的核心部件,一直在畸变入流条件下持续运行,这在很大程度上降低了风扇本身的气动性能。反过来,BLI风扇性能的下降将对飞机的整体气动效益产生严重影响。本文对边界层吸入扇进行了系统的综述。首先,概述了BLI推进系统的气动效益。然后,介绍了不同类型的BLI风扇推进构型,并详细分析了每种构型的畸变流特征。第三,给出了BLI来流变形对风机气动性能的影响,并研究了BLI来流变形对风机气动性能和内部流场的影响。随后,对风机初步设计阶段使用的潜在性能评价方法,主要是低阶计算方法进行了全面综述。最后,对非均匀流入条件下风机/压缩机设计的尝试研究工作进行了综述,并对未来抗畸变BLI风机设计的一些展望进行了展望。本研究的目的是为今后基于BLI风扇推进系统的研究工作提供一些有用的指导。
