Version 1.0.0 of pyVLM

pyVLM is a Python and C-based code implementing the Vortex Lattice Method. It is able to solve the linear potential equation around a set of wings. This equation models inviscid, incompressible flow around the surfaces.

Features

Modelled:

• Effect of the camber line
  • Arbitrary airfoils in Selig format
  • NACA 4-digit airfoils
• 3D aerodynamics
• Incompressible flow
• Wake interaction:
  • Effect of the free or flat wake on the aerodynamics
• Vertical and horizontal tail
• Control surfaces:
  • Aileron and flap
  • Rudder
  • Elevator
• Unsteady phenomena

Limitations

Not modelled:

• Airfoil thickness
• Compressible flow
• Viscous effects
  • Flow separation
• Fuselage
