Stallion 3D is an easy-to-use 3-dimensional aerodynamics software for analyzing UAV designs (and other vehicles) that were developed in a CAD program and saved as .stl files. Stallion 3D uses an ordinary PC running Windows (XP, Vista or 7). Grid generation is automatic. The software can be used to validate designs early in the design cycle to prevent project-stopping errors and speedup the production process. Stallion 3D can be used to select the best designs for further testing and evaluation. The following steps are used to analyze the entire 3D aircraft. Import the Solid Model
Stallion 3D requires a watertight solid model saved as a .STL file. This model (shown in the above picture) was developed by Hanley Innovations for demonstration purposes (HIUAV1). It uses NACA 4512 airfoils for the main wing and NACA 0012 for the tail. It features a blocked inlet on the lower surface of the fuselage, swept wings (25 degrees) and twin tails.
Grid Generation is automatic and captures the flow
boundaries The pictures below show the grid about various components of the aircraft. Grid generation is automatic and no user intervention is required to generate the grid.
The above picture shows the grid about the fuselage.
The above picture shows the grid about the main wing and tail.
The above picture shows the grid about the twin tail.
Analysis
The above picture shows the surface pressure computed by Stallion 3D.
The above picture shows the streamlines generated by the program. Notice the flow features at the tip of the wing.
Stallion 3D computes the lift, drag and moment coefficients. The program also computes forces based on the flow field conditions.
The above picture shows the pressure coefficient computed on the front and rear surfaces.
