3DFoil Software for 3D Wing & Hydrofoil Design and Analysis

Learn How to Design & Analyze a Flying Wing with 3DFoil

3DFoil is a fast and accurate software package for Windows 7, 8 and 10 for analyzing finite (3D) wings, keels, rudders and hydrofoils. It gets its speed and accuracy from our novel numerical algorithm that couples the vortex lattice method (based on vortex rings) with a linear strength panel method. Together, these two methods compute accurate values of the lift, drag (both profile and vortex) and moments.

3DFoil has an easy to use interface that enables accurate design and analysis of 3D interacting surfaces (up to 8 in 3DFoil) based on your airfoil cross sectional shapes. The software is used to design wings or hydrofoils with finite spans, taper, twist, dihedral angles and sweep (forward or backward). It is an excellent tool for developing effective winglets, kite hydrofoils, L-foils and other aerodynamic surfaces.

Wing analysis in 3DFoil is more accurate than 2D airfoil analysis because it computes the lift for a finite span of any aspect ratio, the vortex drag and the profile drag. In addition, 3DFoil can perform a full stability analysis for multiple wings that also outputs the angle of flight and the stability derivatives (longitudinal and lateral) for any configuration.

The above tutorial shows how the software is used to design and analyze a flying wing.

3DFoil is a lite version of MultiSurface Aerodynamics with 8 surfaces instead of 30. Please click here for more information about Mutisurface Aerodynamics.

3DFoil requires a PC, Laptop or tablet running MS Windows XP, Vista, 7, 8 or 10.

Unique Vortex Lattice Approach

Aerodynamics conceptual design and analysis is fast and accurate using 3DFoil. The following analysis methods and tools are available in the software:
  • A vortex-lattice method based on vortex rings
  • A linear strength vortex panel methods for airfoil analysis
  • A novel solution of the ordinary differential equation form of the boundary layer equation for computing profile drag.
  • The ability to analyze any wing shape or wing combination including wings with sweep, twist, dihedral and winglets. MSA can determine drag reduction due to your unique winglets and airfoil cross sectional designs because it computes both profile and induced drag using a fast & accurate proprietary approach.
  • Compute and graph Cl, Cd and Cm vs. angle of attack sweeps for 3-D wing and hydrofoil systems.

Stability Analysis

3DFoil computes the following:
  • Angle of flight
  • Yaw angle (slide slip angle) due to a cross flow
  • Roll rate about CG location (due to control surface deflection or non-symmetric surface)
  • Yaw rate about CG (due to control surface deflection or non-symmetric surface)
  • Rate of change of yaw moment with respect to side slip
  • Rate of change of roll moment with respect to side slip
  • Rate of change of roll moment due to roll rate
  • Rate of change of yaw moment due to yaw rate
