5. UNDERLYING MISSION To Harvest Energy from High Altitude Winds 250m 100m 250m P1546210/2/2014 5

6. PROBLEM STATEMENT & DELIVERABLES The goal of this project is to design, build, and reliably test a powered, human-controlled tethered glider specifically for use as an airborne wind energy system (or AWT)  Tethered glider capable of continuous circular flight  Integration with current base station  30 flights, each 3 minutes or longer, with tether tension and glider position recorded  Functional simulation of flight path P1546210/2/2014 6

7. CUSTOMER NEEDS Customer Need #ImportanceDescription CN19Tethered glider system (with electric prop assist for launching) that demonstrates at least 3 minutes of continuous circular flight path with taunt tether. CN21Clean appearance CN39Human controlled plane CN43No special flight skill required CN59Use existing base station design CN69Tether tension is measured and recorded during flights CN79Tether direction is measured and recorded during flights CN89Videos with accompanying data files of all flight tests (even ones that don’t work) CN99Able to survive crashes with minor repairs (short downtime) CN109Replaceable Parts CN113Maintenance Guide P1546210/2/2014 7
