9632042 Kovacevic This GOALI/Graduate Student in Industry award will support two graduate students as they explore gas turbine efficiency improvements made by innovations in fine hole laser drilling. The amount of compressed air needed to cool turbine blades can be reduced with precise and accurate control of size, shape and orientation of the small film cooling holes on the turbine blade. Pratt and Whitney and Control Vision are the industrial collaborators on this award. The graduate students will be in residence at Pratt and Whitney for the experimental work, using a newly developed industrial vision system provided by Control Vision for sensing in the laser drilling process. They will investigate H-infinity adaptive control methods and Mu-synthesis robust control designs for the laser drilling process, using vision feedback of the hole size and shape. This technical approach is a high pay-off opportunity. Predictions are that with these improvements in precision hole making technology it may be possible to improve gas turbine efficiency by 0.5% without changing the turbine design. This precise control of fine hole making has many other manufacturing applications.

9632042 Kovacevic 该 GOALI/工业研究生奖将支持两名研究生探索通过细孔激光钻孔创新来提高燃气轮机效率。 通过精确控制涡轮叶片上的小气膜冷却孔的尺寸、形状和方向，可以减少冷却涡轮叶片所需的压缩空气量。普惠公司和 Control Vision 是该奖项的工业合作者。 研究生将在普拉特惠特尼大学进行实验工作，使用 Control Vision 提供的新开发的工业视觉系统进行激光钻孔过程中的传感。他们将利用孔尺寸和形状的视觉反馈，研究激光钻孔过程的 H-infinity 自适应控制方法和 Mu-synthesis 鲁棒控制设计。 这种技术方法是一个高回报的机会。 预测通过精密孔加工技术的这些改进，在不改变涡轮机设计的情况下，可以将燃气轮机效率提高 0.5%。 这种对精细孔加工的精确控制还有许多其他制造应用。
