DLMPro (Doublet Lattice Method): This tool calculates the Aerodynamic Influence Coefficients (AIC) for a panel definition for a wing.
Updated 15 Apr 2022



This class sets up a Doublet-Lattice-Model for a given Wing Several Methods are provided for calculating the Aerodyanmic Influence Coefficients

All Calculations are performed in MATALB.

For more detailed Information on methods see Documentation see "supplemental Software"


  • Examples can be found in the "Example_Folder"


  • Non-Planar configuations do not work
  • Optimised for available definition of the wing


  • more detailed description of the wing in form of sections and regions
  • non-planar configurations
  • surface-body interactions


  • This tool is currently in developement and therefore purely experimentaly!
  • It is tested and validated against various models calculated with NX NASTRAN, however errors cannot be excluded
