I am especially interested in
applying of aircraft wing’s pressure distribution estimated in VSPAERO and transform the pressure
distribution into discrete Finite Element Modell - Nastran solver.
I built simple wing model in
OpenVsp program and run the aerodynamic analysis:
The Aerodynamic calculation
results displayed in VSPAERO results manager revealed discontinuity of graph curve:
lift coefficients Cl vs. wing
span coordinate Y in vicinity of transition zone between flaps/ailerons and
wing.

The Calculation of Total Lift
Force Lz in calculation spreadsheet according to Cl coefficients stored in
file: wing-with-controls.lod showed important change of wing’s Total Lift Force
Lz.
There is possible to avoid:
- above mentioned huge
discontinuity in Cl distribution along wing span coordinate Y between wing and
controls components (huge difference of Cp distribution on wing between wing
and controls components)?
VSPAERO Viewer results for
