Abstract Details

2014, Master of Science, Miami University, Computational Science and Engineering.
A proposed design to reduce airframe noise emissions by attaching a flexible fairing between the flap and trailing edge of airplane wings has inspired new research into aeroelastic phenomena in plates and plate-membranes. These flexible plates are susceptible to aeroelastic instabilities which are influenced by aerodynamic loading, axial loading, and boundary conditions. In this research, the aeroelastic behavior of a rectangular plate is considered. The structural system is modeled using the Rayleigh-Ritz method and the piston theory is used to approximate the aerodynamic loading. The effects of the boundary support stiffness, dynamic pressure, and static in-plane loading on the flutter and buckling instability boundaries are explored. Control strategies employing a robust pole placement method, a unique control gain method, and the linear quadratic regulator method are used to improve the open loop stability boundary, allowing for an increase in the operational envelope of the aeroelastic plate system.
