VSP exports to a variety of formats including .stl files. This allows you to export your solid model for additive manufacturing or analysis in Stallion 3D and other CAE programs:
Vehicle Sketch Pad and Stallion 3D (or similar program) are ideal tools for rapid aerodynamics conceptual design and analysis of aircraft. Stallion 3D can import the aircraft geometry in a single step using the .STL import function under the Design menu:
It's easy to import a STL file from VSP into Stallion 3D
Once the aircraft is imported in Stallion 3D, it will generate a grid and analyze the aircraft with a single click. The user can also select the speed and other parameter for the aircraft. In the following case for the Boeing 747-400, the speed is 290 meters/second and the angle of attack is 5 degrees:
This analysis shows the surface pressure and the Cp at various span locations.
Once you design and analyze one vehicle in VSP and Stallion 3D, it is hard to stop. The following pictures show the pressure on the surface of two of the other complete aircraft that comes with VSP:
Pressure on surface of Cirrus aircraft included in VSP.
Pressure on the surface of Cessna aircraft included in VSP
In short, NASA Vehicle Sketch Pad is a fun program to download and design aircraft. It is even more fun to use Stallion 3D to analyze the aircraft and test the design in a digital wind tunnel.
