摘要
吸附式风扇/压气机是目前国内外高增压比压缩系统的一个重要研究方向.对其产生的背景,研制的必要性,技术特点以及研究动向进行了回顾和分析.这一技术的采用能够大幅度提高压比,减少发动机的轴向长度和重量,降低风扇的噪音;在做功能力增加重量减轻的同时,能够增加飞行器的灵活性以及有效载荷,从而减少燃油消耗.但是这种新型的结构也带来了强度、气弹稳定性等问题,对此给出了一些分析结果和建议.
Aspirated fan/compressor（ASFC） is an integral part of high pressure ratio compression system. So, the background, necessity, technical features and research trend of ASFC were reviewed and analyzed. With ASFC technology,it shall be possible to increase efficiently fan/compressor pressure ratio, but also reduce the axial length and weight of the engine as well as the noise of fans. Meanwhile, it increases the flexibility and payload of the flight vehicle,thus reducing the fuel consumption. However,this new structure also leads to some problems in strength and aeroelasticity, so some analytical results and suggestions are presented.
