MultiElement Airfoils is Listed Among
SAE
Aerospace Engineering Magazine
"Top Products for 2003".
MultiElement Airfoils 4.1 solves the compressible Euler &
Navier-Stokes equations for arbitrarily placed objects 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. MultiElement
Airfoils displays 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). It 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.
Applications
Benefits
-
Solve conflicting wing design problems that call for high lift at
landing and takeoffs but low drag and efficiency in the cruise
configuration.
-
Solve the problem of generating high lift when the wing dimensions
are fixed by the rules of the competition.
-
Analyze multiple airfoils shapes without the hassles of grid generation.
Just drag the airfoils into place (or enter their exact location), size and
rotate them and click the menu to automatically generate your grid.
-
Accurately solves compressible Euler & Navier-Stokes equations
for for multiple airfoils and other 2-dimensional shapes.
