R15901: airborne wind energy plane Voice of the Customer R15901: airborne wind energy plane

Background Airborne wind energy planes are designed to simulate the tip of the conventional wind turbine blade Operate at higher altitudes than conventional wind turbines Multiple methods to harness the energy Tether reel system Turbines on-board the plane conducted through tether Figure 1: Diagram showing swept areas of a conventional horizontal axis wind turbine(HAWT) and an tethered airfoil system.

Current State of the Art in Industry Makani Uses on-board turbines with electrified tether Most recent model generates 600 kW of power Fully autonomous vertical circular flight path Flies at an altitude of 140 m -310 m Ampyx Uses reel system to generate electricity Fully autonomous infinity-shaped flight path Flies at an altitude of 300 m – 600 m http://plates55.com/wp-content/uploads/2011/12/mak_slide1_x900.jpg http://http://www.ampyxpower.com/OurTechnology.html

Current State of the Art in MSD P14462 Designed a Base Station Provided tether connection point Collected tether tension and position data of the plane Used a bought plane 3-point bridle system Achieved 3-5 continuous vertical circles P15462 Designed a plane Designed to perform continuous vertical circles Using a 1-point bridle system Implementing previous Base Station for DAQ Currently manufacturing and assembling plane

Objectives for Continuation Goals: Design an airborne wind energy system that implements a continuous horizontal circular flight path. Implement a tether control system to perform reeling of the tether in flight. Collect position, orientation, and tether tension as a function of time of the plane in flight.
