A User-Friendly Expert System for Airfoil Design and Boundary
Layer Stability Analysis

Abstract:

The quest for performance, fuel efficiency, range and speed in
the current global economic environment, has sparked a renewed
interest in designing and analyzing lamianar flow wings for
airplanes. Currently, the capability to design and analyze
laminar flow wings only exists at large commercial aircraft
companies and government research organizations. These stability
analysis methods currently require "expert" input choices, as
well as "expert" interpretation of the results. The innovation
proposed is to develop a user friendly graphical user interface
(GUI) based laminar flow analysis system. This system will
integrate a flow analysis solver, a boundary layer-mean flow code
and a stability analysis code into an icon based control program.
Expert input provided by the development team's experience will
be coded into the control program's database. The value of this
practical application program development is that applied
aerodynamicists will finally have a laminar flow airfoil design
and analysis tool. The commercialization of this application
software to applied engineers in GA, universities and other
industries will be invaluable, and act as a catalyst for
designing the next generation of advanced high performance
aircraft.

The user-friendly expert stability analysis system will find a
market place in numerous establishments conducting NLF or LFC
airfoil/wing design. Possible users are GA companies of both
certified and experimental aircraft, universities for
aerodynamics students and engineers at large commercial aircraft
companies. Individuals interested in wing design can use the PC
based version.
