摘　　要：齿轮传动涡扇(Geared turbofan,GTF)发动机作为绿色航空动力的代表机型,在降低耗油率、噪声、减少污染物排放等诸多方面具有突出优势。以完善我国关于GTF发动机知识参考、引起国内学者关注该技术研究为目的,详细介绍了GTF发动机的发展背景和研究现状,以求抛砖引玉之效。重点针对其关键部件-行星齿轮传动系统的动力学问题,包括系统建模、动特性及非线性响应、功率均载、试验及故障模拟方面,做了详细评述,同时基于GTF发动机结构提出其可能面临的故障问题,最后总结了技术难点概况,并指出需要进一步研究的问题。As the representative of green aerodynamics, the geared turbofan (GTF) aero-engine has some advantages including lower fuel consumption rate, less noise, minor pollutant emission and so on. Aiming at supplementing the knowledge reserve of GTF and causing our country scholar's concern, the GTF aero-engine is introduced in some key fields, such as development background and research status. The main presentation focuses on the dynamic responses of planetary gear transmission system. It is detailed reviewed in system modelling, dynamic characteristics vs nonlinear dynamics, and power load sharing and especially experiment and fault simulation study. The possible faults for GTF aero-engine are addressed. The technological difficulties and further studies needed are given at last.
