Blades

The blade geometrical, aerodynamic and structural (mass and stiffness) properties can be defined, including:

• Full or partial span pitch or aileron control.

• Blade sweep and pre-bend.

• Comprehensive aerofoil interpolation.

• Blade vibration dynamics, in and out of plane, and flap-twist coupling.

• Model for iced blades.

• Blade vibration dampers.

• Encryption facility for blade and aerofoil data.

• Aerodynamic model uses blade element momentum theory with dynamic inflow and stall hysteresis, and full aeroelastic feedback from structural motions.
