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
