Integrated Conceptual Design and Analysis

Stallion 3D Version 4.0 (New!) represents a leap forward in the area of the conceptual design and the subsequent aerodynamics analysis of wings and other streamlined components.  In addition to the capability to analyze the actual geometry of the full sized air frame,  the software is equipped with an integrated geometry tool for designing and editing multi-element wings, keels, rudders, struts and other components.  Once these components are designed within Stallion 3D, it is a very simple matter to perform a 3D Reynolds Averaged Navier-Stokes solution on the part such as the rear wing spoiler show in the following picture.

Rear wing Spoiler Design (the colors represent pressure).

The aerodynamics components are interactively constructed by entering the span, taper (left and right chord lengths), sweep (forward or backwards) and dihedral angles.  In addition, airfoils are assignable to the lift and right chords (linear aerodynamic twist). 

Once the components are designed, the software can then compute the lift, drag, moments and related aerodynamic coefficients.  The user enters the airspeed, angle of attack, side slip angle and fluid type (air or water).  The setup of the CFD solution takes only a few seconds because Stallion 3D utilizes automatic grid generation as part of the solution process.

The following video demonstrates how to use Stallion 3D to design and analyze a rear wing spoiler for a sports car.

As the video demonstrates, post processing of the aerodynamics data is also included within the Stallion 3D user interface.  Stallion 3D will export all components in the STL format.
