Some Model Parts |
Forward fuselage surface was lofted in SurfaceWorks, a fully associative SolidWorks add-in, using a B-Spline surface supported by B-Spline control curves. The surface was then used to cut a solid in SolidWorks.
Duct geometry was created very simply in SolidWorks by revolving an imported spline curve defining the airfoil section.
Wing Panel was lofted in SolidWorks on imported splines. |
Elevator (left) and stabilizer were lofted in SolidWorks on splines created in a further custom program. The software takes any wing section and calculates points files for a flap of arbitrary planform and circular leading edge, along with the associated forward surface, while maintaining specified clearances. This software also facilitates the 3D modeling of the stators/statorons and fins/rudders. Ailerons are independent foils. Aft fuselage is a revolved, shelled solid in SolidWorks. |
The propeller blades depicted here were lofted in SolidWorks on 13 spline profiles, each containing 140 coordinate points. These profiles (points files) were created using custom FORTRAN software which reads XROTOR geometry data, along with airfoil coordinate data for several airfoils of various thickness; the software then works out (with user input) a suitable thickness distribution, and computes sections at arbitrary blade stations.
