Aeroelastic and Flight Dynamics Analysis of Folding Wing Systems
(2013)This dissertation explores the aeroelastic stability of a folding wing using both theoretical and experimental methods. The theoretical model is based on the existing clamped-wing aeroelastic model that uses beam theory ... -
Component Modal Analysis of a Folding Wing
(2011)This thesis explores the aeroelastic stability of a folding wing with an arbitrary number of wing segments. Simplifying assumptions are made such that it is possible to derive the equations of motion analytically. First, ... -
Coupled-Mode Flutter for Advanced Turbofans
(2010)In the vast majority of measured turbomachinery blade flutter occurrences, the response occurs predominately in a single mode. The primary reason for this single-mode flutter is that for turbomachinery applications ... -
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 ... -
Inflected wings in flight: Uniform flow of stresses makes strong and light wings for stable flight.
(Journal of theoretical biology, 2021-01)Flying animals morph and flex their wings during their flight. Their wings morph with the turbulent flow created around them. The wings of modern airplanes do not have this ability. In this study we show that the ability ... -
Linear Aeroelastic Stability of Beams and Plates in Three-Dimensional Flow
(2012)The aeroelastic stability of beams and plates in three-dimensional flows is explored as the elastic and aerodynamic parameters are varied. First principal energy methods are used to derive the structural equations of motion. ... -
Physical Insights, Steady Aerodynamic Effects, and a Design Tool for Low-Pressure Turbine Flutter
(2016)The successful, efficient, and safe turbine design requires a thorough understanding of the underlying physical phenomena. This research investigates the physical understanding and parameters highly correlated to flutter, ... -
Stability of Beams, Plates and Membranes due to Subsonic Aerodynamic Flows and Solar Radiation Pressure
(2014)This dissertation explores the stability of beams, plates and membranes due to subsonic aerodynamic flows or solar radiation forces. Beams, plates and membranes are simple structures that may act as building blocks for more ...
