  2. Agenda • Team introduction • Problem definition • Private and academic development • Customer needs • Engineering requirements • Timeline moving forward

  3. Team Introduction

  4. 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

  5. Private Development • Ampyx Power • Tethered Glider • Ground power generation • Figure-8 pattern • Capable of generating 850kW

  6. Private Development • Makani Power • Tethered Glider • Airborne wind turbines • Circular pattern • Tested 30kW; Goal of 600kW

  7. 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

  8. 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].

  9. 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].

  10. Customer Needs

  11. Engineering Requirements

  12. House of Quality

  13. Timeline • Phase 1 (wk 1-3) - COMPLETE! • Define/understand problem definition • Research similar projects • Organize as a team • Phase 2 (wk 4-6) - In progress • Learn to fly • Research production load cells & gliders • Identify/understand critical engineering theory

  14. Timeline • Phase 3 (wk 7-9) • Determine glider design • If building glider from scratch • Identify airfoil types, materials, control/communication features • Develop theoretical simulation of flight • Phase 4 (wk 10-13) • Refine glider design • Refine theoretical simulations • Phase 5 (wk 14-15) • Order materials
