MultiSurface Aerodynamics easily models complex wing geometries using multiple tapered surfaces (up to 30). The software computes the resulting Cl, Cd, Cm, the lift distribution, induced angle of attack distribution, the neutral point, angle of trim, Cl-alpha and Cm-alpha. MultiSurface Aerodynamics includes a body of revolution to simulate an airplane fuselage, a bulb for a keel and other applications.

MultiSurface Aerodynamics is used by engineers, designers and students as an interactive tool to design and immediately analyze aircraft wings, aircraft wing and body combinations, sailboat keels, bulbs & rudders, race car spoilers, hydrofoils and other aerodynamics concepts directly on their personal computer.

The software computes longitudinal and lateral static stability derivatives and other parameters necessary for efficient flight. It includes a built-in stand-alone airfoil analysis tool that computes Cl, Cd & Cm for general airfoil shapes.

Aerodynamics conceptual design and analysis is fast and accurate using MultiSurface Aerodynamics. 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.

MultiSurface Aerodynamics 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 roll moment due to yaw rate
- Rate of change of yaw moment due to yaw rate

"For this study, the aerodynamic forces and moments are computed using MultiSurface Aerodynamics (MSA)14 software."

"The aerodynamics of the aircraft is computed using a commercial code called MultiSurface Aerodynamics (MSA)[10]."

"Each board was analyzed with Hanley Innovations 3DFoil software to assess the lift and drag of the main shaft (vertical portion of the daggerboard) and the tip (horizontal portion). There is a significant carryover of the lift from one foil section to the other ..."
