Air Vehicle Configuration Design
Air vehicle configuration design leverages the talents and requirements of many disciplines. Configuration designers need to be able to balance multiple conflicting quantitative and qualitative requirements in a way that: Recent advances in capability and applications for UAV configurations bring new opportunities and challenges to the configuration designer. The opportunity is to take advantage of […]
Interdisciplinary Foundations of Flutter: Insights from the Aeroelastic Triangle
Aeroelastic characteristics are defined by the interaction between structural dynamics and the incremental aerodynamics developed by the deformed surfaces. A standard depiction of this interaction is the aeroelasticity triangle. This one is from the classic text ‘Aeroelasticity’ by Bishplinghoff, Ashley, and Halfmann, universally called ‘BAH’: A gratifying result for us Flutter enthusiasts is that Flutter appears front […]

Understanding Flutter: The Feedback Loop Behind Aerodynamic Stability in Aircraft
Flutter is the engineering study of potentially unstable interactions between the aerodynamic forces on an air vehicle and the deformation due to those forces. The formal name for these studies acknowledges interaction in ‘aeroelastic stability’ by combining the terms ‘aerodynamic’ and ‘elasticity’. All flight vehicles experience forces due to traveling through the air. This is a requirement […]

TLG presented at AIAA SciTech 2025
Peter Burns presented a paper “Automated Method for Rapid Estimation of Aeroelastic Wing Shapes – TLG StarBeam” at AIAA SciTech on January 7, 2025. which he co-authored with Andrew McComas and Andy Magstadt. The topic was TLG Aerospace’s internally developed code ‘StarBeam’ which brings aeroelastic capability within our workhorse CFD code Star-CCM+. StarBeam couples a […]
TLG Aerospace is Your Trusted Partner for CFD Services
From designing cutting-edge aircraft to predicting aerodynamic performance, computational fluid dynamics (CFD) plays a pivotal role at all stages of the product lifecycle. Since we were just in the wind tunnel last month (see our post here), we thought it would be fun to discuss how CFD can be used as a virtual wind tunnel. […]
