FIELD: power plants converting energy of medium to mechanical energy. SUBSTANCE: wing is mounted on moving structure for rotating about its own axis. It is provided with device that functions to vary its angle of attack by turning about its shaft through kinematic link of flap mounted on its ...
[translate] aWith an increase in angle of attack the wing is closer to the Critical angle of attack. 以在迎角的增量翼是离重要迎角较近。[translate]
Wing twisting can be an effective way to bank, and a means to control roll in the post-stall regime (complex flight condition often accompanied by a loss of control beyond the critical angle of attack) when applied only in the outer regions of the wing20. It has been shown that ...

The invention is directed to an apparatus for attaching to a wing operating in a fluid medium for increasing the angle of attack at which the wing experiences aerodynamic/hydrodynamic stall. The wing includes upper and lower surfaces extending between a leading edge and a trailing edge and having...
3. Boundary conditions. Check them carefully. Especially while defining the angle of attack. 4. Are you using auto time scale? Yes I'm using auto time scale, I couldan't? Boundary conditions I´ve difined Inlet as u = Ux V = Uy ...
