MultiElement Airfoil Analysis for Compressible/Incompressible Flows

MultiElement Airfoils

MultiElement Airfoils is a computer aided engineering (CAE) tool for calculating the aerodynamics of isolated or multiple airfoil shapes interacting in a flow field. Engineers and design professionals use it to rapidly and accurately compute aircraft, marine and automobile flow scenarios on an ordinary Windows based PC, notebook or tablet computer.

MultiElement Airfoils is a turn-key product that eliminates grid generation hassles and accurately computes lift, drag and moments for a group of airfoils and individual airfoils within the group. The software generates graphs of pressure, Mach number, temperature and total pressure using built-in post processing tools (it does not require additional third party software for pre or post processing).

MultiElement Airfoils is an excellent tool for optimizing cross-sectional shapes and getting the correct placement of aerodynamics components for aircraft, automobiles, boats, house hold products and other equipment.

Interactive Airfoil CFD

The full MultiElement Airfoils 5.0 solves the compressible Euler & Navier-Stokes equations for up to 20 arbitrarily placed airfols in subsonic, transonic and supersonic flows. It is a turn-key product that eliminates grid generation hassles and accurately computes lift, drag and moments for a group of airfoils and individual airfoils within the group.

Instant Flow Analysis

MultiElement Airfoils also uses a linear-strength vortex panel method to instantly analyze multiple airfoils in subsonic flows. The novel boundary layer solver accurately predicts transition, separation and stall. The program computes Cl, Cd and Cm for your custom airfoil shapes in addition the UIUC library and NACA 4, 5 and 6-digit airfoils. Watch Video

" To design an inventive multi-element airfoil, Computational Flow Dynamics Analysis (CFD) was used. Specifically, the CFD program created by Dr. Patrick Hanley was used to design the inventive airfoil. A description of the methods used to design the airfoils according to embodiments of the invention is also presented in Appendix A of the related U.S. Provisional Application No. 61/322,783. "

Application in Racing

The F1 DRS (drag reduction system) allows drivers to safely overtake each other in a race. One second before passing another car, the driver can activate the DRS. Actuating the system changes the geometry of the rear wing and affect the aerodynamics in two ways. First, down force (often a good thing) is reduced while drag (a bad thing) is decreased in magnitude.
