Aeroelastic Instabilities due to Unsteady Aerodynamics
(2015)One of the grand challenges faced by industry is the accurate prediction of unsteady aerodynamics events, including frequency lock-in and forced response. These aeromechanical incidents occurring in airplane engines and ... -
Design for Coupled-Mode Flutter and Non-Synchronous Vibration in Turbomachinery
(2013)This research presents the detailed investigation of coupled-mode flutter and non-synchronous vibration in turbomachinery. Coupled-mode flutter and non-synchronous vibration are two aeromechanical challenges in designing ... -
Flutter and Forced Response of Turbomachinery with Frequency Mistuning and Aerodynamic Asymmetry
(2008-04-25)This dissertation provides numerical studies to improve bladed disk assembly design for preventing blade high cycle fatigue failures. The analyses are divided into two major subjects. For the first subject presented in Chapter ... -
Multi-Row Aerodynamic Interactions and Mistuned Forced Response of an Embedded Compressor Rotor
(2016)This research investigates the forced response of mistuned rotor blades that can lead to excessive vibration, noise, and high cycle fatigue failure in a turbomachine. In particular, an embedded rotor in the Purdue Three-Stage ...
