Continuous Dynamic Simulation for Morphing Wing Aeroelasticity

The morphing of an air vehicle is to change its shape and size substantially during flight. Thus, the morphing vehicle is to achieve a broader range of operational modes, all of which will maximize the vehicle performance throughout its mission profile. The dream of human flight has been to mimic birds or insect flights in similar manner since the days of Leonardo da Vinci. Our current aeronaut...

An Automated Design Synthesis Method for Compliant Mechanisms with Application to Morphing Wings

An automated design synthesis method is developed to design an airfoil with a reconfigurable shape, which can change from one type of geometry to another. A design synthesis method using unit truss approach and particle swarm optimization is presented. In the unit truss approach, unit truss is used as a new unit cell for mechanics analysis of cellular structures, including lightweight structure...

Static Nonlinear Aeroelasticity of Flexible Slender Wings in Compressible Flow

A high-fidelity numerical formulation is presented for the high-speed aeroelastic behavior of slender composite wings. The compressible flow is modeled using the 3-D Euler equations on a deformable mesh, and an asymptotic approximation of the 3-D kinematically-nonlinear equations of elasticity models the anisotropic slender structure. The transfer of the distributed loads and displacements at t...

Camber effects in the dynamic aeroelasticity of compliant airfoils

This paper numerically investigates the effect of chordwise flexibility on the dynamic stability of compliant airfoils. A classical two-dimensional aeroelastic model is expanded with an additional degree of freedom to capture time-varying camber deformations, defined by a parabolic bending profile of the mean aerodynamic chord. Aerodynamic forces are obtained from unsteady thin airfoil theory a...

Folding in and out: passive morphing in flapping wings.

We present a new mechanism for passive wing morphing of flapping wings inspired by bat and bird wing morphology. The mechanism consists of an unactuated hand wing connected to the arm wing with a wrist joint. Flapping motion generates centrifugal accelerations in the hand wing, forcing it to unfold passively. Using a robotic model in hover, we made kinematic measurements of unfolding kinematics...
