  • Sofware Development: TFLAMES

  • Developed for the U S Air Force under the Engine Rotor Life Enhancement Program (ERLE) as an SBIR effort, Peregrine Consulting designed and delivered two phases of automated life cycle analysis software.

    This software program is known as Turbine Field Life Analysis Multi-physics Engine Simulation (TFLAMES). for the US Air. It is a physics-based, non-linear tool employing a 3D finite element core that is specifically designed to calculate the stresses and lives of critical rotating parts in turbine engines, especially for as-flown mission conditions.
