Introduction to Kit. Ves 01 EU-PROJECT KITVES ● Airfoil-based solution for Vessel on-board energy production destined to traction and auxiliary services ● Working height: 200 m – 1000 m ● Kite is equipped with sensors and independent power supply ● Actuators and steering in the unit on deck (Kite Steering Unit) ● Autonomously performed cyclic two-phase manoeuvre: traction and recovery phase ● Surface of the Kite: 25 m² ● Rotation angle around Z-axis: 480° ● Nominal power: 100 k. W Financed within the 7 th Framework of the EU C. Hartmann, P. Winzer ● Source: Kit. Ves project www. kitves. com www. fgproqu. uni-wuppertal. de Page 7

Introduction to Kit. Ves 01 HARVESTING CYCLES: TRACTION PHASE ● Kite is lifted by the wind à Elliptic ascent of the kite maximizes the amount of generated energy Lines unroll ● Drums are put in rotation ● Generators produce energy. C. Hartmann, P. Winzer ● www. kitves. com www. fgproqu. uni-wuppertal. de Page 8

Introduction to Kit. Ves 01 HARVESTING CYCLES: RECOVERY PHASE ● Started by the control when the maximal length of the lines is reached ● Lines are pulled in by the motors with a short delay between the first and the second line Wing area exposed to the wind is minimized à Kite can be pulled in with a minimal effort, using only a small fraction of the energy generated in the traction phase At minimal length: new traction phase starts C.
