Aero-Thermodynamic Distortion Induced Structured Dynamic Response.

Abstract

This final report summarizes the results obtained on Grant AFOSR-91- 025. The overall objective of this basic research program was the quantitative investigation of the fundamental phenomena relevant to aero-thermodynamic distortion induced structural dynamic blade responses in multistage gas turbine engines and the study of the fundamental unsteady aerodynamics and heat transfer phenomena inherent in turbines. The technical approach involved unique benchmark experiments and also analyses. In particular, the flow physics of multistage blade row interactions were investigated, with unique unsteady aerodynamic data obtained and analyses developed to understand, quantify, and discriminate the fundamental flow phenomena as well as to direct the modeling of advanced analyses.
