Problem Definition
  • Goal: Design, build, and test a tethered, small-scale, human-controlled glider.
  • Critical project objectives
    • Maintain maximum tension on the tether
    • Sustaining horizontal and vertical flight paths
    • Measure/record tether tension & position
    • Understand the influential parameters for sustained, tethered, unpowered flight

academic papers
Academic Papers
  • Loyd
  • 1980 Paper outlining how to harness high altitude wind energy
  • 3 Different Methods
    • Simple Kite
    • Crosswind Powered Kite
    • Drag Powered Kite
      • Uses turbines on kite rather than a ground based generator
