摘　　要：F-35B对转升力风扇对于提升国产舰载机的性能具有重要的参考价值,回顾了其发展历史以及围绕该种升力风扇开展的科学研究,强调了该种升力装置的特点和优势。在考虑地面效应对升力影响的前提下进行了初步的一维设计,认为总压比设计在2.3时符合升力要求。重点介绍了短距/垂直起降飞机升力风扇的设计、非定常流动结构和稳定性等问题。对转风扇/压气机有关研究对对转升力风扇的研究具有借鉴意义。对转升力风扇研究中缺少实验研究和复杂流动结构机理不明等问题需引起重视。The improvement of the F-35B counter-rotating lift fan is important for the aircraft carrier.Reviewing its development history from research papers shows that this lift device has outstanding features and advantages.The design,unsteady flow structure and stability of the lift fan in short/take-off and vertical landing(STOVL)aircraft were mainly presented,also showing that it is proper to set the total pressure ratio to a value of2.3for one-dimensional design,including the effect of suckdown.Studies on counter-rotating fan/compressor have a strong link to the research of the lift fan.Technical problems remaining in the lift fan,such as the lack of experimental research and the analysis of complex flow structures should attract more attention,since it poses threats to the steady operation of the lift fan.
