Team Introduction Problem Definition Presentation 9/9/2013 P14462
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 Tether Base Station Operator w/ controller Problem Definition Presentation 9/9/2013 P14462
Private Development • Ampyx Power • Tethered Glider • Ground power generation • Figure-8 pattern • Capable of generating 850kW Problem Definition Presentation 9/9/2013 P14462
Private Development • Makani Power • Tethered Glider • Airborne wind turbines • Circular pattern • Tested 30kW; Goal of 600kW Problem Definition Presentation 9/9/2013 P14462
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 Problem Definition Presentation 9/9/2013 P14462
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]. Problem Definition Presentation 9/9/2013 P14462
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]. Problem Definition Presentation 9/9/2013 P14462
