Aerodynamic Design

TLG offers a wide range of aerodynamic design services to support customers in any phase of their aircraft design from conceptual to detailed design and beyond. Whether the need is basic sizing and conceptual design, detailed design, trade studies, optimization, or modification to existing aircraft, TLG has direct experience. Our specialized tools and in-house expertise ensure an efficient workflow and consideration for the complete aircraft. Emphasis is placed on the overall aircraft to ensure features work in harmony and the design is practical to manufacture, maintain, and operate.

Our full suite of Computational Fluid Dynamics (CFD) capabilities is extremely valuable in this design process. We have direct experience in aerodynamic design covering aircraft types ranging from small general aviation to large transport aircraft and even hypersonic autonomous aircraft.

Tools

Successful design starts with the ability to understand and simplify the problem. Then, having the right analytical tools is key.

TLG employs a variety of tools with the ability to scale fidelity to fit the problem at hand. We use XFOIL and MSES for airfoil design, empirical methods, vortex lattice, CFD for aerodynamic characteristics, and in-house developed methods for linear/nonlinear S&C and flight dynamics simulations.
