abstract

  • The consequences of varying wing geometries through morphing on aeroelastic stability are assessed. The first analysis considers a wall-mounted configuration for an airfoil section of a two-dimensional wing. This system consists of a torsional spring at the trailing edge flap hinge. Equations of equilibrium are obtained and its behavior is studied within the context of divergence and reversal. The second analysis examines a highly flexible flying wing configuration, subject to a transient morphing scheme. The unmorphed and morphed geometries are obtained using a morphing trailing edge wing prototype, and the structural modeling and cross-sectional properties are obtained using the open source mesh generator GMSH and the Variational Asymptotic Beam Sectional Analysis (VABS). Implications of the geometric variations on the aeroelastic stability are ascertained, using the computer program Nonlinear Aeroelastic Trim and Stability Analysis of High Altitude Long Endurance Aircraft (NATASHA). Results obtained from this study indicate that morphing the system has auspicious effects on the aeroelastic stability of the system, namely in terms of flutter characteristics.
