Research Interests

Nonlinear Aeroelasticity

Aeroelasticity is a field that focuses on the interactions between the structure and the aerodynamics. An aircraft is an inherently fluid-structure coupled problem as the aerodynamic shape determines the loads, which affect the structure, and causes deformation (change in shape). Classically, aeroelastic analysis was conducted using linear models, and is sufficient to predict aeroelastic responses like divergence, flutter and control reversal. Nonlinear aeroelastic analysis is essential when either the structural deformations are large (and thus outside the linear range) or the aerodynamic loads are nonlinear. The focus of the present research is on two specific topics:

  • Nonlinear aeroelasticity of high-aspect-ratio wings
  • Limit cycle oscillations in fighter aircraft

Flight Dynamics of Flexible Vehicles

Aeroelasticity is the interaction of aerodynamics and elasticity. Most research in the field of aeroelasticity is either based on computational simulation or wind-tunnel experimentation, and is restricted to cantilevered wing analysis. In-flight aeroelasticity experiments can capture the interdependence of the aeroelastic characteristics of the flexible structure and the flight dynamics of the aircraft. The flight testing will be complemented by theoretical analysis of complete aircraft that includes flight dynamic analysis as well as aeroelasticity. Studying these interactions is important to understand the dynamic response of a flexible aircraft. Research conducted in the laboratory will help in the design and development of new unconventional aircraft. The focus of this work is two-fold:

  • Determine the effect of flexibility on the flight dynamics of a flexible aircraft
  • Determine the effect of flight dynamics (rigid-body modes) on the aeroelastic response of the aircraft
