本文对利用热管技术冷却燃气轮机涡轮叶片的基本可行性和预期效益进行了评估。这一概念包括将叶片内部装配成热管，将叶片延伸到相邻的散热器中，然后将叶片入射的热量通过叶片传递到散热器。基线是一台先进的军用战斗机发动机，旁路空气是选择的散热器。研究结果表明，采用该技术后，发动机推力提高了7.2%，单位油耗降低了0.2%，发动机重量增加了不到1%。版权所有：1994，ASME
This paper evaluates the basic feasibility and anticipated benefits to using heat pipe technology to cool the turbine vanes of gas turbine engines.This concept involves fitting out the vane interior as a heat pipe, extending the vane into an adjacent heat sink and then transferring the vane incident heat through the vane to the heat sink. The baseline is an advanced military fighter engine and the bypass air is the chosen heat sink. The results of this study show a 7.2% increase in engine thrust, a 0.2% decrease in specific fuel consumption with engine weight increased by less than 1% by using this technology.Copyright © 1994 by ASME
