Aerodynamic Design


Aerodynamic design usually starts with the wing and the airfoil shape, but quickly extends to the full outer surface of the aircraft. Along with designing a smooth, low drag shape, aerodynamic design includes providing good stability and control and handling qualities.

What Tools Does TLG Use for Aerodynamic Design?

TLG employs a variety of tools including Fun2D and MSES for airfoil design, vortex lattice methods for stability derivatives and STAR-CCM+, a full Navier Stokes CFD solver, capable of unsteady analysis with coupled fluid-body 6DOF simulation and heat transfer. But even with sophisticated tools, the most important aspect to successful design is being able to simplify the problem and use the appropriate tool for the job. This is where TLG’s wide range of experience in the design process will save you time and money.

What Design Experience Does TLG Have?

TLG engineers have direct experience in many aspects of aerodynamic design ranging from airfoil section optimization to jet engine inlet design all the way up to clean sheet aircraft design.

Why Would I Do Wind Tunnel Testing?

Another area of expertise is in wind tunnel testing. With computers getting faster every day, some people are surprised that wind tunnel testing is still a key tool for aircraft design. While it’s true that Computational Fluid Dynamics (CFD) tools are getting faster and more accurate, there is still no substitute for wind tunnel testing when the goal is to gather large amounts of data in short amounts of time. Wind tunnel testing is also more reliable for difficult flow regimes including separated flow, stalled flow and unsteady high speed shock formations. TLG engineers have extensive experience in all aspects of wind tunnel testing and can help you through all stages of the test process including test planning, wind tunnel model design and specifications, test execution, real-time data processing and analysis and post-test data reduction. Wind tunnel time is highly productive, but also very expensive; make the most of it!
