  • 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

  • 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

Academic Papers

Three axis load cell system created by Lansdorp et al.Image taken from [Lansdorp 2007].

Lansdorp

  • Two Different Arrays of Kites
  • Pumping Mill
  • Laddermill
  • Created a system to measure the

tension magnitude and direction using 3D load cell assembly

  • Basis for our system

Donnelly

  • Fighter Kites
  • Theoretical model to predict motion of

fighter kite

  • Created a method to control the fighter

kite motion

  • Created an experimental rig with

generator and variable tether length similar to Lansdorp’s.

Academic Papers

Three axis load cell allowing for variable tether length created by Chris Donnelley. Image taken from [Donnelly 2013].
