U.S.-Russian Cooperative Research: Investigation of the Effects of Bowed Stator Blades on the Flow in Axial Compressors

该奖项支持美俄合作研究弯曲定子叶片对轴向压气机流动的影响。这项研究工作将由弗吉尼亚联邦大学的丹尼尔·j·多尼博士和莫斯科中央航空发动机研究所的维克多·萨伦博士领导。本研究希望通过使用(1)弯曲翼型来提高燃气涡轮压气机的效率，这种翼型旨在减少端壁附近的叶片负荷，从而最大限度地减少二次流；(2)翼型时钟，即在相邻的旋转和非旋转叶片排中调整翼型的周向位置，以减少不稳定和总压力损失。该项目的实验部分将由莫斯科的科学家进行，而该项目的计算部分将由弗吉尼亚联邦大学、德克萨斯农工大学和波士顿大学的研究人员进行。这项工程研究实现了将美国和俄罗斯的顶尖专家聚集在一起的项目目标，在平等、互惠和互利的基础上，在共同感兴趣和能力强的领域结合互补的努力和能力

INT-9902358DorneyThis award supports U.S.-Russian cooperative research on the effects of bowed stator blades on the flow in axial compressors. The research effort will be headed by Dr. Daniel J. Dorney of Virginia Commonwealth University and Dr. Victor Saren of the Central Institute of Aviation Motors in Moscow. This study expects to improve the efficiency of gas-turbine compressors through the use of (1) bowed airfoils, which are airfoils designed to reduce blade loadings near endwalls, and thus minimize secondary flows, and (2) airfoil clocking, which is adjusting the circumferential location of airfoils in adjacent rotating and non-rotating blade rows to reduce unsteadiness and total pressure losses. The experimental portion of the program will be performed by scientists in Moscow, while the computational portions of the program will be undertaken by researchers at Virginia Commonwealth University, Texas A&M University, and Boston University.This research in engineering fulfills the program objectives of bringing together leading experts in the U.S. and Russia to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.***
