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. -

Jet Ski for the Song of the Same Name by Bikini Kill, See Reject All American. Jet Ski Is the Brand Name of a Personal Watercraf
Jet Ski From Wikipedia, the free encyclopedia (Redirected from Jet skiing) For the song of the same name by Bikini Kill, see Reject All American. European Personal Watercraft Championship in Crikvenica Waverunner in Japan Racing scene at the German Championship 2007 Jet Ski is the brand name of a personal watercraft manufactured by Kawasaki Heavy Industries. The name is sometimes mistakenly used by those unfamiliar with the personal watercraft industry to refer to any type of personal watercraft; however, the name is a valid trademark registered with the United States Patent and Trademark Office, and in many other countries.[1] The term "Jet Ski" (or JetSki, often shortened to "Ski"[2]) is often mis-applied to all personal watercraft with pivoting handlepoles manipulated by a standing rider; these are properly known as "stand-up PWCs." The term is often mistakenly used when referring to WaveRunners, but WaveRunner is actually the name of the Yamaha line of sit-down PWCs, whereas "Jet Ski" refers to the Kawasaki line. [3] [4] Recently, a third type has also appeared, where the driver sits in the seiza position. This type has been pioneered by Silveira Customswith their "Samba".

January — March 2009
JanuaryJanuary —- March March 2009 2009 WKA — a nonprofit organization dedicated to helping people know how much fun it is to fly kites! What You Need for a Successful Kite Festival? Who’s going to do that? Maybe we could all take turns. Flyers The people who set up the fields could make kids kites and Kites then go help at the potluck and then help with the raffle and Space the cleaning up? Wind and there is one more thing. What would that be? Do you think that will work? Scott, what do you think we need? Well that is what usually happens. Marla, you know what that is! That way everyone else can just have fun and fly their kites. I do? Marla, I know what we are missing. You know, what are they Yes! It would be those other people that do things. Like set called? You always see them at every event doing all the up fields. work. We need someone to be an announcer. Maybe Bob or Robin would do that? I got it! They are called VOLUNTEERS! Then we need someone to fill out nametags and register Great Scott, but where do we find them? people. Maybe I could do that and I will bring the wristbands. You ask and they will come. We need some safety people. Scott, would you call Dick and Now you are in a field of dreams. see if he would do that job. He would make a good field marshal. I know Marla, but we can always hope. Marla, should we have a potluck and maybe a raffle? Put it on the calendar and we will make it work. -
Kitesurfing a - Z
Kitesurfing A - Z A Airfoil (aerofoil): a wing, kite, or sail used to generate lift or propulsion. Airtime: the amount of time spent in the air while jumping. AOA, Angle of Attack: also known as the angle of incidence (AOI) is the angle with which the kite flies in relation to the wind. Increasing AOA generally gives more lift. AOI, Angle of Incidence: angle which the kite takes compared to the wind direction Apparent wind, AW: The wind felt by the kite or rider as they pass through the air. For instance, if the true wind is blowing North at 10 knots and the kite is moving West at 10 knots, the apparent wind on the kite is NW at about 14 knots. The apparent wind direction shifts towards the direction of travel as speed increases. Aspect Ratio, AR: the ratio of a kites width to height (span to chord). Kites can range between a high aspect ratio of about 5.0 or a low aspect ratio of about 3.0. AR5: The legendary first 4 line inflatable kite manufactured by Naish. ARC: a foil kite manufactured by Peter Lynn B Back Loop: a kitesurfing trick where the kiter rotates backward (begins by turning their back toward the kite) while throwing his/her feet above the level of his/her head. Back Roll: same as a back loop but without getting their feet up high. Batten: a length of carbon or plastic which adds stiffness or shape to the kite or sail. Bear Away / Bear Off: change your direction of travel to a more downwind direction. -
A COMMERCIAL of the SHELF COMPONENTS for a UNMANNED AIR VEHICLE PHOTOGRAMMETRY Pawel Burdziakowski ABSTRACT a Photogrammetry
Section Name A COMMERCIAL OF THE SHELF COMPONENTS FOR A UNMANNED AIR VEHICLE PHOTOGRAMMETRY Pawel Burdziakowski Jakub Szulwic Faculty of Civil and Environmental Engineering, Gdansk University of Technology, Poland ABSTRACT A photogrammetry from a unmanned aerial vehicle (UAV) can be understood as a new measurement tool. Is introduces a low-cost alternatives for a traditional aerial photogrammetry. A commercial off-the-shelf products (COTS), that are commercially available for a costumers, are the standard manufactures products, not custom. COTS products are available in the commercial market and can be bought and used under government contract. That fact makes it cheaper and available for all. Motivations for using COTS components is a reduction of overall system-development and costs and long-term maintenance costs. An aviation offers a different types of aircraft. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion. All those types offers different attributes, that are more or less desirable for UAV photogrammetry. A methodology for determining a platform type was developed in this research, and the most suitable platform for a photogrammetry measurements was chosen. In order to build a UAV platform for photogrammetry tasks, products available on commercial market were analyzed with characteristics and technical data. Keywords: COTS, UAV, photogrammetry, methodology INTRODUCTION Commercial off-the-shelf (COTS) products can be defined as an items, including services, sold in the commercial marketplace. This is a standard manufactures products, not specially designed for custom purposes. This item is commercially available, leased, licensed and sold to the general public. COTS products not require special modification or maintenance over its life cycle. -
American Kitefliers Association
AMERICAN If Dreams Had Wings… KITEFLIERS The AKA was founded in 1964, but it wasn’t until 1978 that the organization ASSOCIATION held its first convention in Ocean City, Maryland. Now, 40 years later, the AKA is excited to celebrate by returning to Ocean City to fly on the same beach where it all started so long ago. The dreams of those kite pioneers will be NATIONAL CONVENTION flying high this October 9-14. As a flying location, the Ocean City beach has been declared by some to be th 40 ANNUAL “The Kiteflying Capital of the World” due to its wide beach, regular winds, and the community’s support of kiteflying. Attendees can fly into the local COMPETITION AND Salisbury/Ocean City airport or drive down from Washington or Baltimore. The kiteflying will be held on the beach between the Kite Loft and our host FESTIVAL hotel, The Park Place. There is a wide range of other accommodations within an easy walk. OCEAN CITY, MARYLAND Ocean City has a modern convention center just a few miles from the flying fields. Convention registrants will be able to take a free shuttle to and from the OCTOBER 9-14, 2017 convention center simply by showing their registration badges. At the center, we will hold our auction, banquets, and meetings. There is a great indoor flying facility for Wednesday night which is something you won’t want to miss. Ocean City Photography by On Thursday night, the Fly Market will open with new fanfare as many kite Jo-Ann Rasmussen manufacturers have agreed to set up their booths to display what’s new for 2018.
