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. We’re big fans of real-world testing, but we think you get more value when you combine it with CFD-based predictions.

Below are a few of the advantages CFD has over a wind tunnel which make it a complementary tool.

◾ Upfront costs and schedule – Wind tunnel models are expensive and take time to build. These costs pay off once you are in the tunnel, but CFD has a much lower cost and lead time to seeing the first actionable results. Further, CFD allows teams to refine their early-stage concepts quickly, which means a design is much more mature by the time you enter the tunnel.

◾ Maximizing value – During a wind tunnel test campaign, time is a limited resource, and you want to extract the most value you can. Having a good set of CFD-based predictions allows the test engineers to focus on key strategic objectives or to troubleshoot unexpected results. One example is simulating full-scale Reynolds numbers in a low-speed (non-pressurized) tunnel. Full and model-scale CFD results can help the test crew employ techniques to approximate full-scale results.

While software and cloud computing have come a long way, you still need a team that knows how to interpret and deliver actionable results. TLG offers our customers world-class CFD services led by our in-house expert Dr. Peter Burns. Before joining TLG, Peter was the global aerospace technical specialist for Siemens PLM Software supporting their STAR-CCM+ software. Check out Peter and the rest of our leadership team, as well as a complete look at our engineering service offering, at

Save the Date – Aircraft Structural Loads: Criteria, Analysis, and Validation Course Led by TLG’s Dr. Josh Dementi in Seattle, WA.

Did you know one of TLG’s esteemed engineering managers also leads a course in aircraft structural external loads through The University of Kansas? Dr. Josh Sementi is overflowing with knowledge in the area.

In addition to engineering manager with responsibilities for loads, dynamics, and flutter, Josh is also an independent consultant FAA Loads DER with full approval authority for both 14 CFR Parts 23 and 25 airplanes and is an alumnus of the University of Washington where he earned his Doctor of Science degree in aerospace engineering. In the past, he has taught courses at Seattle U and for the UW Grad program.

A long-time colleague and friend to TLG team members, Josh joined TLG from Aviation Partners Boeing where he led the loads and dynamics engineering department in support of Supplemental Type Certificates for winglet installations on Boeing 737 Next Generation, 757, and 767 transport aircraft; and Dassault Falcon 2000 business jets. This experience includes both performing and directing MSC; Nastran aeroelastic analyses, with extensive use of Matlab tools for additional analysis and data processing.

Josh recently wrapped teaching The University of Kansas’ high-level survey course offered annually, which helps give perspective on aircraft structural external loads analysis (including criteria, design, analysis, fatigue, certification, validation, and testing) to regulators, flight test engineers, flutter, and aerodynamics disciplinaries, and more. The transfer of knowledge from Josh and the course content helps participants stay engaged with loads and how to best utilize loads outputs and ask the right questions as to what needs to be done.

The traveling course was held in San Diego in 2023 and will take place here in Seattle this year. Please Save the Date to get expert insight from Dr. Sementi, April 8-12, 2024, at the DoubleTree Suites by Hilton Hotel Seattle Airport Southcenter.
