Development of a gas turbine engine starts with optimization of the working process parameters. Turbine inlet temperature is among the most influential parameters that largely determine performance of an engine. As typical turbine inlet temperatures substantially exceed the point where metal turbine blades maintain reasonable thermal strength, proper modeling of the turbine cooling system becomes crucial for optimization of the engine’s parameters. Currently available numerical models are based on empirical data and thus must be updated regularly. This paper reviews the published information on turbine cooling requirements, and provides an approximation curve that generalizes data on all types of blade/vane cooling and is suitable for computer-based optimization.

燃气涡轮发动机概念设计阶段冷却流量的估算

燃气涡轮发动机的开发始于工作过程参数的优化。涡轮入口温度是最有影响力的参数之一,在很大程度上决定了发动机的性能。由于典型的涡轮入口温度大大超过金属涡轮叶片保持合理热强度的点,因此涡轮冷却系统的正确建模对于优化发动机参数变得至关重要。当前可用的数值模型基于经验数据,因此必须定期更新。本文回顾了有关涡轮机冷却要求的已发布信息,并提供了近似曲线,该曲线可以概括所有类型的叶片/叶片冷却的数据,并且适合基于计算机的优化。
