涡轮冷却技术被广泛应用于航空发动机及燃气轮机涡轮研发中，冷却空气的引气量成为影响整机效率的重要因素之一。本文基于现代燃气轮机及航空发动机涡轮叶片采用外部冷却与内部冷却结合的复合冷却的技术发展背景，综述了国内外在冷却空气量对涡轮叶片冷却性能影响方面的研究进展，分析并总结了冷却空气量对气膜冷却、交错肋冷却以及对综合冷却效率的影响规律，并对未来的研究方向给出了一定的建议。分析表明：对气膜孔形状的探索是未来气膜冷却技术研究的重点；交错肋研究主要处于定性研究阶段，对定量研究方法的探索是目前的发展趋势；对综合冷却效率的研究还处于起步阶段，未来可以从外部冷却和内部冷却之间的相互作用关系方面对综合冷却效率开展进一步的研究。

Turbine cooling technology is widely used in the development of aero engines as well as gas turbines. The entrainment volume of cooling air has become one of the important factors affecting the efficiency of the whole unit. Based on the technological development background of modern gas turbine and aeroengine turbine blades adopting compound cooling combining external cooling and internal cooling, this paper reviews the research progress on the influence of the cooling air volume on the cooling performance of turbine blades both at home and abroad, analyzes and summarizes the influence law of the cooling air volume on the film cooling, the matrix cooling as well as the overall cooling efficiency, and makes certain suggestions for the direction of the future research. The analysis shows that the exploration of the shape of film holes is the focus of future research on film cooling technology; the study of matrix cooling is still mainly in the stage of qualitative research, and the exploration of quantitative research methods is the current development trend; the study of overall cooling efficiency is still in the initial stage, and in the future, further research can be carried out from the aspect of the interaction relationship between external cooling and internal cooling on the overall cooling efficiency.
