    • A method for designing gas turbine engine components using a coupled parametric analysis of part geometry and flow control is disclosed. Included are the steps of parametrically defining the geometry of the duct wall shape, parametrically defining one or more flow control actuators in the duct wall, measuring a plurality of performance parameters or metrics (e.g., flow characteristics) of the duct and comparing the results of the measurement with desired or target parameters, and selecting the optimal duct geometry and flow control for at least a portion of the duct, the selection process including evaluating the plurality of performance metrics in a pareto analysis. The use of this method in the design of inter-turbine transition ducts, serpentine ducts, inlets, diffusers, and similar components provides a design which reduces pressure losses and flow profile distortions.
    • 公开了一种使用零件几何和流量控制的耦合参数分析来设计燃气涡轮发动机部件的方法。 包括参数定义管道壁形状的几何形状的步骤,参数地定义管道壁中的一个或多个流量控制致动器,测量管道的多个性能参数或度量(例如,流动特性),并比较 所述测量具有期望的或目标参数,以及为所述管道的至少一部分选择最佳管道几何形状和流量控制,所述选择过程包括在帕累托分析中评估所述多个性能度量。 在涡轮机过渡管道,蛇形管道,入口,扩散器和类似部件的设计中使用这种方法提供了减少压力损失和流量失真的设计。
