Problem definition

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

Glider

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

Academic papers1

Academic Papers

  • 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

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

Academic papers2

Academic Papers

  • 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.

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