Computational Tools Used By Seair: From the beginning, Seair has used PC-based tools to help study and understand WIG craft design in ways unavailable to experimenters in the 1960's and '70's.

Early in our studies, commercial PC software was not widely available for the kinds of tasks at hand, so much of the initial simulation, analysis, performance estimates, and lofting tools were custom written in-house. As time progressed we have been able to employ a range of commercially available software tools.

Computational tools employed in Seair studies have included the following examples...

• Specialized 3D surface lofting software
• 3D Computer Aided Drafting (CAD)
• Custom Airfoil Design & 2D Analysis
• 3D Computational Fluid Dynamics (CFD)
• Performance and Vehicle Sizing Codes
• Structural Finite Element Models
• Batch-processed 3 and 5-D.O.F. vehicle dynamics simulations
• Piloted operational simulations
• Spreadsheet-based vehicle cost and weight estimation
• Project planning tools
• 3D solids rendering and animation
