I took on the role of chairman but I’m still not sure how this Chairman Len Royles all came about! So this is my first official post in the NKG magazine. This year I think will be described as an “annus horribilis” for the Len stood down as disruption of everyday life as we know it. I fear that for a lot of people, Chairman after six life will never be the same again. We have never experienced this years but will continue before.

Optimal Control of Power Kites for Wind Power Production
FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Optimal Control of Power Kites for Wind Power Production Tiago Costa Moreira Maia PREPARATION FOR THE MSC DISSERTATION Master in Electrical and Computers Engineering Supervisor: Fernando Arménio da Costa Castro e Fontes Co-Supervisor: Luís Tiago de Freixo Ramos Paiva February 7, 2014 c Tiago Costa Moreira Maia, 2014 Abstract Ground based wind energy systems have reached the peak of their capacity. Wind instability, high cost of installations and small power output of a single unit are some of the the limitations of the current design. In order to become competitive the wind energy industry needs new methods to extract energy from the wind. The Earth’s surface creates a boundary layer effect on the wind that increases its speed with altitude. In fact, with altitude the wind is not only stronger, but steadier. In order to capitalize these strong streams new extraction methods were proposed. One of these solutions is to drive a generator using a tethered kite. This concept allows very large power outputs per unit. The major goal of this work is to study a possible trajectory of the kite in order to maximize the power output using an optimal control software - Imperial College London Optimal Control Software (ICLOCS), model and optimize it. i ii Contents 1 Introduction1 1.1 Context . .1 1.2 Motivation . .2 1.3 Objectives . .2 1.4 Document Structure . .2 2 State of the Art5 2.1 High Wind Energy . .5 2.2 High Wind Energy Systems . .6 2.3 The Laddermill . .9 2.3.1 Dynamic Model the Tethered Kite System . -

An Introduction and Brief History
KITES An Introduction and Brief History SKY WIND WORLD.ORG FLYING A ROKAKKU - FLYING BUFFALO PROJECT HISTORY From China kites spread to neighboring countries and across the seas to the Pacific region. At the same time they spread across Burma, India and arriving in North Africa about 1500 years ago. They did not arrive in Europe or America until much later probably via the trade routes Kites are thought to have originated in China about 3000 years ago. One story is that a fisherman was out on a windy day and his hat blew away and got caught on his fishing line which was then when these areas developed. blown up in to the air. Bamboo was a ready source of straight sticks for spars and silk fabric was available to make a light covering, then in the 2nd century AD paper was invented and is still used to this day. PHYSICS Kites fly when thrust, lift, drag and gravity are balanced. The flying line and bridle hold the kite at an angle to the wind so that the air flows faster across the top than the bottom producing the lift. THE PARTS OF A KITE 1 THE SAIL • This can be made of any material such as paper, fabric or plastic. • It is used to trap the air. The air must have somewhere to escape otherwise it spills over the front edge and makes the kite wobble. This can be done by using porous fabric or making it bend backwards to allow the air to slip smoothly over the side.
