Loads
TLG Engineering has the skills, experience and tools to generate loads appropriate for all stages of aircraft development, from quick preliminary design loads to final certification loads. Analyzing loads early in the design cycle is key to reducing program risk and cost. TLG has two in-house Loads DERs, Steve Muenzberg.and Dr. Josh Sementi. LEARN MORE >
Flutter
All aircraft must be shown to be free from flutter for flight safety and per civil and military airworthiness requirements. TLG can perform the required certification flutter analyses for all required aircraft configurations and conditions. We can also plan and participate in the required ground and flight testing and subsequent analysis. TLG has an in-house Flutter DER, Robert Lind. LEARN MORE >
Aerodynamic Design
Aerodynamic design touches all aspects of an aircraft Outer Mold Line (OML), from airfoil optimization to engine inlets to flight control surface sizing. TLG has extensive experience in aerodynamic design and optimization on projects ranging from clean sheet design to stability and control enhancements on existing aircraft. LEARN MORE >
Computational Fluid Dynamics (CFD)
Computational Fluid Dynamics (CFD) refers to the process of calculating how a fluid, usually air, flows around an object. TLG has the tools and experience to provide CFD analysis ranging from quick and simple lifting line to full Navier Stokes volume flow with heat transfer and reacting gas chemistry. LEARN MORE >
Performance Analysis
Accurately predicting aircraft performance throughout the design cycle is critical to the success of a program. TLG has the experience and tools necessary to get timely, accurate performance estimates when making business and design decisions at the beginning of a program, adjust performance data due to modifications as the program matures, and create the accurate predictions needed in flight test.

Handling Qualities Analysis
TLG has the tools needed to analyze aircraft stability and control. TLG has extensive experience in how and why airplanes exhibit good and bad handling qualities, how to test and quantify these behaviors, and what modifications can be used to deal with unacceptable characteristics. TLG has an in-house Flight Analyst DER, Robert Lind. LEARN MORE >
Dynamic Simulation
Dynamic simulation is a multidisciplinary process that combines an aerodynamic model with mass properties, propulsion, and control inputs to simulate the flight path of a flight vehicle. When well-implemented, the tool is valuable to a program since specific flight maneuvers can be repeatably re-flown enabling Monte Carlo studies, envelope definition, or procedure development.

Store Separation
TLG has strong experience with store-safe separation analysis and risk mitigation. We utilize multi-fidelity tools that have been validated against industry standard codes. Our methods allow for the modeling of higher-order effects including complex mutual interferences, unsteady aerodynamics, ejector/umbilical forces, and release maneuvers. LEARN MORE >
