  • 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.

  • Kap Guide BBHD
    Notes on K I T E A E R I A L P H O T O G R A P H Y I N T R O D U C T I O N This guide is prepared as an introduction to the acquisition of photography using a kite to raise the camera. It is in 3 parts: Application Equipment Procedure It is prepared with the help and guidance from the world wide KAP community who have been generous with their expertise and support. Blending a love of landscape and joy in the flight of a kite, KAP reveals rich detail and captures the human scale missed by other (higher) aerial platforms. It requires patience, ingenuity and determination in equal measure but above all a desire to capture the unique viewpoint achieved by the intersection of wind, light and time. Every flight has the potential to surprise us with views of a familiar world seen anew. Mostly this is something that is done for the love of kite flying: camera positioning is difficult and flight conditions are unpredictable. If predictable aerial imagery is required and kite flying is not your thing then other UAV methods are recommended: if you are not happy flying a kite this is not for you. If you have not flown a kite then give it a go without a camera and see how you feel about it: kite flying at its best is a curious mix of exhilaration, spiritual empathy with the environment and relaxation of mind and body brought about by concentration of the mind on a single object in the landscape.

    CRANFIELD INSTITUTE OF TECHNOLOGY STEPHEN E. HOBBS A QUANTITATIVE STUDY OF KITE PERFORMANCE IN NATURAL WIND WITH APPLICATION TO KITE ANEMOMETRY Ecological Physics Research Group PhD THESIS CRANFIELD INSTITUTE OF TECHNOLOGY ECOLOGICAL PHYSICS RESEARCH GROUP PhD THESIS Academic Year 1985-86 STEPHEN E. HOBBS A Quantitative Study of Kite Performance in Natural Wind with application to Kite Anemometry Supervisor: Professor G.W. Schaefer April 1986 (Digital version: August 2005) This thesis is submitted in ful¯llment of the requirements for the degree of Doctor of Philosophy °c Cran¯eld University 2005. All rights reserved. No part of this publication may be reproduced without the written permission of the copyright owner. i Abstract Although kites have been around for hundreds of years and put to many uses, there has so far been no systematic study of their performance. This research attempts to ¯ll this need, and considers particularly the performance of kite anemometers. An instrumented kite tether was designed and built to study kite performance. It measures line tension, inclination and azimuth at the ground, :sampling each variable at 5 or 10 Hz. The results are transmitted as a digital code and stored by microcomputer. Accurate anemometers are used simultaneously to measure the wind local to the kite, and the results are stored parallel with the tether data. As a necessary background to the experiments and analysis, existing kite information is collated, and simple models of the kite system are presented, along with a more detailed study of the kiteline and its influence on the kite system. A representative selection of single line kites has been flown from the tether in a variety of wind conditions.

  • Project # DJO-0209 Development of a Wind Monitoring System and Grain
    Project # DJO-0209 Development of a Wind Monitoring System and Grain Grinder for WPI’s Kite Power System An Interactive Qualifying Project Report submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by __________________________ Deepa Krishnaswamy ___________________________ Joseph Phaneuf __________________________ Travis Perullo May 7 th , 2009 _________________________ Professor David Olinger, Advisor Abstract The goal of this project was two-fold: 1) to develop a wind monitoring system to be used during field testing of the WPI kite power system, and 2) to develop a grain grinder accessory for the same system for use in a developing nation such as Namibia. Kite power is emerging as an economically sound alternative energy source as the kites used can operate at higher altitudes than wind turbines. At higher altitudes, wind speed is higher, and hence, a greater amount of power is available. The WPI kite power system operates via a large wind boarding kite, which pulls the end of a long rocking arm. This in turn spins a generator which produces electricity. The developed wind monitoring system consists of a carbon fiber pyramid shaped frame mounted to the underside of a weather balloon with a wind measuring anemometer hung from the frame. Steps taken in the design process include deciding on a deployment system (i.e. how to place the anemometer at the desired altitude), conceptualizing and building a stable frame to mount the anemometer to, constructing a rotating platform and hinge assembly to keep the anemometer vertical and facing normal to the wind, developing MATLAB code to accept the signal transmitted from the anemometer wirelessly, and building the wireless transmitter for the anemometer.

  • Design of a One Kilowatt Scale Kite Power System a Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE
    Project #: DJO - 0308 Design of a One Kilowatt Scale Kite Power System A Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science In Aerospace Engineering SUBMITTED BY: __________________________ __________________________ Ryan Buckley Max Hurgin [email protected] [email protected] __________________________ __________________________ Chris Colschen Erik Lovejoy [email protected] [email protected] __________________________ __________________________ Nick Simone Michael DeCuir [email protected] [email protected] rd Date: April 23 , 2008 __________________________________ Professor David Olinger, Project Advisor 1 Abstract The goal of this project was to design and build a one-kilowatt scale system for generating power using a kite. Kite power has the potential to be more economical than using wind turbines because kites can fly higher than turbines can operate. At higher altitudes, wind speeds and available power are increased. In the developed system, a large windboarding kite pulls the end of a long rocking arm which turns a generator and creates electricity. This motion is repeated using a mechanism that changes the angle of attack of the kite during each cycle, thus varying its lift force and allowing a rocking motion of the arm. The end of the arm turns a shaft with a flywheel attached and spins a mounted generator, whose output then gets stored in batteries for later use. A Matlab simulation was used to predict a power output for the system of approximately one kilowatt. All sub-components of the system (power conversion mechanism, angle of attack mechanism, and kite control mechanism) have been lab tested.
