What is the capability need/knowledge gap being addressed? Off-body, pulsed thermal energy deposition using lasers reduces wave drag and sonic boom but lacks definitive assessment of system energy efficiency. What is the state of the art? CFD analysis of the impact of energy deposition on supersonic shock waves and flow fields assumes instantaneous heating modeled by ideal gas behavior. These assumptions fail to predict experimentally observed flow behavior and are suspect for accurate energy efficiency assessments. What are we proposing to do that is unique? The current effort employs a non-equilibrium thermochemistry model for energy deposition in a full Navier-Stokes solver with laser bench-test experimental validation. For system energy assessment, the force impulse and input/output energy parameters for a Mach 2, blunt wind tunnel model will be tested. What is the end goal? The end goal is to make a definitive assessment of the system energy efficiency of pulsed energy deposition for one case to help enable future advanced vehicle concept developments.
