Overview

One week at DLR (German Aerospace Research Center) in the hypersonic wind tunnel facility. Operated Mach 10 test equipment, calculated airfoil efficiency at hypersonic speeds, and worked through scramjet combustor aerodynamics data. Short duration, high density. The kind of week that recalibrates what you think fast means.


The problem

Get meaningful technical understanding out of one week in a world-class hypersonic research facility.

Constraints
  • One-week duration, which required being selective about what was worth focusing on
  • Test facility safety protocols limited hands-on equipment operation to supervised sessions
Design decisions
  • Concentrated time on aerodynamic analysis over propulsion. More accessible in the available window given existing background.
Build process
  1. 01

    Wind tunnel facility orientation and safety protocol certification

  2. 02

    Mach 10 airfoil testing: data collection and drag/lift coefficient analysis across multiple geometries

  3. 03

    Scramjet combustor aerodynamics: inlet and flow path efficiency analysis


Result

Calculated efficiency curves for several airfoil geometries at Mach 10. Documented scramjet inlet aerodynamics analysis.

What went wrong / what I learned
  • Hypersonic aerodynamics has almost nothing in common with subsonic intuition. Shock interactions and aerodynamic heating dominate everything.
  • High-end research facilities spend more time on calibration and diagnostics than on actual test runs
