Large-scale swept-wing ice accretion modeling in the NASA Glenn Icing Research Tunnel using LEWICE3D
… CFD code, was used to calculate flows around the flapped-hybrid model in the IRT, mounted with the root at the floor and the tip at the ceiling of the test section. Inviscid analysis reveals that the upwash ahead of the model causes the local lift coefficient to increase significantly across the …

Modeling and LQR Control of a Two-Dimensional Airfoil
In this paper we develop a mathematical model of a two-dimensional aeroelastic airfoil. This model is used to design a flutter suppression controller. Flutter is a vibration in a wing caused by airstream energy being absorbed by the lifting surface. Flutter increases with increasing speed. For …

The Influence of Propeller Position and Size on the Aerodynamics of Blown Wings
… The mechanism of blown wing stall when a flap is deployed is identified. It is shown that the flap stalls due to boundary layer diffusion resulting from a combination of the propeller jet and flap incidence. Moving the propeller down vertically increases the maximum lift coefficient, …
