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

INT-9902358 Dorney该奖项支持美国-轴流压气机内弯曲静叶对流动影响的俄罗斯合作研究。 这项研究工作将由弗吉尼亚联邦大学的丹尼尔·J·多伦博士和位于莫斯科的中央航空发动机研究所的维克托·萨伦博士领导。 本研究旨在通过使用（1）弓形翼型（旨在降低端壁附近的叶片载荷，从而最大限度地减少二次流的翼型）和（2）翼型同步（调整相邻旋转和非旋转叶片排中翼型的周向位置，以降低不稳定性和总压损失）来提高燃气轮机压气机的效率。 该计划的实验部分将由莫斯科的科学家执行，而该计划的计算部分将由弗吉尼亚联邦大学、德克萨斯州&农工大学、这项工程研究实现了将美国和俄罗斯的领先专家聚集在一起的计划目标，以联合收割机在具有强烈共同利益和能力的领域互补努力和能力在平等、互惠、互利的基础上 *

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.***
