  • Kites: Pioneers of Atmospheric Research
    Chapter 6 Kites: Pioneers of Atmospheric Research Werner Schmidt, William Anderson Abstract Kites were essential platforms for professional exploration of the atmo- sphere for more than two centuries, from 1749 until 1954. This chapter details the chronology of kite-based atmospheric research and presents a brief examination of the well-documented scientific kiting based at the Royal Prussian Aeronautical Ob- servatory. Parallels are drawn between scientific kiting from then and contemporary power-generation kiting. Basic kite types of the time are presented and the design evolution from those towards advanced payload carriers is discussed. These include the Lindenberg S- and R-Kites, the latter of which featuring an effective passive de- power mechanism. The practices of launch and retrieval of kites and the components developed for this purpose are outlined, in particular those in use at the Meteorolog- ical Observatory Lindenberg. Their methods and techniques represented the state of the art after WWI and lay the groundwork for modern efforts at atmospheric energy extraction using kites. 6.1 Introduction The workhorse for performing tasks at altitude from the mid-1800s up until the ad- vent of the powered airplane in the early 1900s was often the humble kite. These tasks included aerial photography [3], manlifting for purposes of military surveil- lance [28], and although less widely declared, airframe development for later un- tethered, manned flight (most notably the Wright brothers’ wing warping kite of 1899 [18]). Kites were also indispensable in the development of wireless radio and telegraphy, in which kites were used by radio-pioneer and physicist Marconi to lift the first antennae to suitable altitudes for reception of messages transmitted via ra- Werner Schmidt Strengeweg 14, 26427 Holtgast/Utgast, Germany, e-mail: [email protected] William Anderson (B) Advance Paragliders, Uttigenstrasse 87, 3600 Thun, Switzerland, e-mail: [email protected] 95 96 Werner Schmidt, William Anderson dio [7].

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.

  • Kite Flying Is Economical, Tough and Has Half the Stretch of Nylon Lines
    Kite design basics: A kite flies a little like a tethered aircraft – indeed many of the early developers and pioneers such as Sir George Cayley (from Brompton Hall in Yorkshire); the Australian inventor of the ‘Box Kite’, Laurence Hargrave; and the Wright Brothers all used kites in their experiments for man-powered flight. You may wish to use your favourite ‘Search Engine’ to find out about these people using the Internet. Like an aircraft, kites have three main forces acting upon them: LIFT – this is generated by air pressure on the flying surfaces and acts through the Centre of Pressure (CP) (usually the centre of area or ‘Centroid’ of a flat kite) DRAG – this is the kite’s resistance to being pulled through the air and also acts through the centre of area. WEIGHT – this acts though the Centre of Gravity (CG) or balance point of the kite and should be minimised as much as possible by using lightweight materials. The CG can be found by simply balancing the kite on one finger. In addition, kites have a Bridle Point where the kite line (or control line) is attached. The Bridle Point acts like a hinge or pivot and one aim of kite design is to ensure there is enough ‘lift’ and to keep the CG below the CP such that the kite does not tend to tip forward and become unstable. Kite tails are sometimes used to increase drag and lower the CG to achieve more stability. Aircraft wings (airfoils) usually have a curved (or cambered) upper surface and achieve LIFT by being slightly tilted upwards towards the wind.

Nugent, Chairperson Jennifer Griswold Yi-Leng Chen Copyright 2018 by David J. DeCou i ACKNOWLEDGMENTS I would like to express my deepest thanks to my advisor and committee chair, Dr. Alison D. Nugent, who has continuously given me guidance, advice, and encouragement. Through her ever-present support over the course of my graduate education, she has inspired and helped me directly to improve my presentation skills, writing/organizational skills, coding skills, and research skills. Without her experience, expertise, materials, and ideas, this project would not have been possible. I owe my success in this program to her support. I would also like to thank both Dr. Jennifer Griswold and Dr. Yi-Leng Chen for their helpful critique of my thesis and participation in my defense. Their input has greatly improved my work and led to deeper discussion in this project. My scientific writing and overall organization has improved as a result of their help. In addition, Dr. Griswold’s Satellite Applications class has provided me with valuable coding experience in Matlab that helped me in the data analysis for this project significantly. Her class has helped me become more familiar with coding in general. I would also like to sincerely thank the Department of Atmospheric Sciences at the University of Hawaiʻi at Mānoa for providing me with financial support as a graduate teaching assistant during my education here.
