Abstract

The Duhamel superposition principle, applied in unsteady linear aerodynamics, is extended to arbitrary nonlinear lift curves. The unsteady lift due to arbitrary wing motion is generated using the static nonlinear lift curve. A finite-state unsteady aerodynamic model that is based on a two-state approximation of Wagner function is developed. As such, it is suitable for dynamic stability analysis and control synthesis for the systems experiencing nonlinear unsteady flows such as wind turbine blades, rapidly maneuvering aircraft, highly flexible wings, and micro-air-vehicles. The proposed unsteady model is applied to flapping flight and validated through a comparison with direct numerical simulations of Navier-Stokes on hovering insects.
