A common platform for validation of aircraft drag reduction technologies

The main purpose is to identify candidate solutions/technologies to reduce interference drag. The ability to compare with the reference solution is a key element.

Whatever the flow solver, models and numerical schemes, we should always have a simulation with the reference geometry for comparisons.

    • Chose a mathematical modelling and flow solver
    • Analyze reference configuration
    • Analyze reference configuration with installed full solution
      • Similar mesh density
      • Identical flow solver parameters, turbulence models, etc.
      • Iso-lift: match the lift of the reference configuration with variation of angle of attack
      • Similar level of convergence. Analysis of lift and drag convergence histories
    • Analyze reference configuration with installed full solution and flow control device switched off, for identifying the contribution of the flow control devices (previous case was nalyzed with flow control switches on)
      • Identical parameters and mesh as the step 3
    • Asses the cost of the installed device
      • Energy consumption
      • Weight
      • Other limitations
