Nonlinear Aeroelastic Analysis of Aircraft with High-aspect-ratio Wings

The paper describes a formulation for aeroelastic analysis of aircraft with high-aspect-ratio wings. The analysis is a combination of a geometrically-exact mixed formulation for dynamics of moving beams and finite-state unsteady aerodynamics with the ability to model dynamic stall. The analysis also takes into account gravitational forces, propulsive forces and rigidbody dynamics. The code has ...

Aeroelastic Roll Control for High Aspect Ratio Wings

The undersigned hereby certify that they have read and recommend to the Faculty of Aerospace Engineering for acceptance a thesis entitled " Aeroelastic Roll Control for High Aspect Ratio Wings " Summary Modern aircraft tend to be light and slender. The high aspect ratio reduces the induced drag, increase fuel efficiency, and provide enough lift at low speeds. Therefore such wing types are used ...

Inherent Stability Modes of Low-Aspect-Ratio Wings

The development of micro aerial vehicles has been hindered by a poor understanding of the flight dynamics associated with the unique aerodynamic regime. This study experimentally estimates the aerodynamic damping derivatives of flat-plate wings with aspect ratios less than 3 at a Reynolds number of 7.5 × 104; when combined with previously published results detailing the lateral and longitudinal...

Aeroelastic Analysis of Composite Wings

An aeroelastic stability analysis is presented for high-aspect ratio composite wings. The structural model is based on an asymptotically correct crosssectional formulation and a nonlinear geometric exact beam analysis, both derivable from 3-D elasticity. A new 2-D unsteady inflow finite-state theory is considered for the aerodynamic part of the solution. Theodorsen theory is also implemented an...
