Aerodynamic Design and Improvements

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

TLG has 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.

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; However, even with top-notch tools, the key to successful design starts with the ability to simplify the problem. Afterwards, we can determine the appropriate tool for the job. This is how TLG’s wide range of experience in the design process will save you time and money on your next project.
