LiftingLine + GXBeamAssembly

LiftingLineGXBeamAssembly()

Construct a model by coupling a lifting line aerodynamic model and a geometrically exact beam theory model (as implemented by GXBeam). Parameters for this model are defined in LiftingLineGXBeamParameters.

NOTE: When using this model, the local frame for each beam element is assumed to be oriented with the x-axis along the beam's axis, the y-axis forward (into the freestream), and the z-axis in the airfoil normal direction.

LiftingLineGXBeamParameters(Vinf, rho, beta; kwargs...)

Defines parameters for a lifting line model coupled with a geometrically exact beam theory structural model when subjected to a the freestream velocity vector Vinf.

Arguments

• Vinf: Freestream velocity vector
• rho: Air density
• beta: Prandtl-Glauert compressibility factor $\beta = \sqrt{1 - M^2}$
