STARTUP and FRANCES KINNEAR WITH 84 ILLUSTRATIONS AND DIAGRAMS LONDON JOHN LANE THE BODLEY HEAD LTD, English edition first published in 1930 PRINTED IN GREAT BRITAIN BY THE BOWERING PRESS, PLYMOUTH Foreword THE motorless AIRPLANE, i.e. the GLIDER or SAIL PLANE, is steadily growing in popularity, and is, in the truest sense of the word, the flying sport of youth. This book represents the collective results of the writers' experiments since 1921 in motorless flight, and particularly in gliding, related in a way most likely to be useful to others. In flying, more than in anything, every experience and triumph individually won by hard endeavour should be triumph and experience won for all. Its aim is to state as clearly as possible all the beginner ought to know of Gliding and Gliding Machines. Hie theories it contains are explained in such a manner as to be easily under stood. The finest airmen are often hopelessly bad mathematicians and Flying as a Sport should, as far as possible, be made easy for everybody. FRITZ STAMER and ALEXANDER LIPPISCH. -

FURTHERDEVELS'NENT OF THETUNNY RIG E M H GIFFORDANO C PALNER Gi f ford and P art ners Carlton House Rlngwood Road Hoodl ands SouthamPton S04 2HT UK 360 1, lNTRODUCTION The idea of using a wing sail is not new, indeed the ancient junk rig is essentially a flat plate wing sail. The two essential characteristics are that the sail is stiffened so that ft does not flap in the wind and attached to the mast in an aerodynamically balanced way. These two features give several important advantages over so called 'soft sails' and have resulted in the junk rig being very successful on traditional craft. and modern short handed-cruising yachts. Unfortunately the standard junk rig is not every efficient in an aer odynamic sense, due to the presence of the mast beside the sai 1 and the flat shapewhich results from the numerousstiffening battens. The first of these problems can be overcomeby usi ng a double ski nned sail; effectively two junk sails, one on either side of the mast. This shields the mast from the airflow and improves efficiency, but it still leaves the problem of a flat sail. To obtain the maximumdrive from a sail it must be curved or cambered!, an effect which can produce over 5 more force than from a flat shape. Whilst the per'formanceadvantages of a cambered shape are obvious, the practical way of achieving it are far more elusive. One line of approach is to build the sail from ri gid componentswith articulated joints that allow the camberto be varied Ref 1!. -
The International Flying Dutchman Class Book
THE INTERNATIONAL FLYING DUTCHMAN CLASS BOOK www.sailfd.org 1 2 Preface and acknowledgements for the “FLYING DUTCHMAN CLASS BOOK” by Alberto Barenghi, IFDCO President The Class Book is a basic and elegant instrument to show and testify the FD history, the Class life and all the people who have contributed to the development and the promotion of the “ultimate sailing dinghy”. Its contents show the development, charm and beauty of FD sailing; with a review of events, trophies, results and the role past champions . Included are the IFDCO Foundation Rules and its byelaws which describe how the structure of the Class operate . Moreover, 2002 was the 50th Anniversary of the FD birth: 50 years of technical deve- lopment, success and fame all over the world and of Class life is a particular event. This new edition of the Class Book is a good chance to celebrate the jubilee, to represent the FD evolution and the future prospects in the third millennium. The Class Book intends to charm and induce us to know and to be involved in the Class life. Please, let me assent to remember and to express my admiration for Conrad Gulcher: if we sail, love FD and enjoyed for more than 50 years, it is because Conrad conceived such a wonderful dinghy and realized his dream, launching FD in 1952. Conrad, looked to the future with an excellent far-sightedness, conceived a “high-perfor- mance dinghy”, which still represents a model of technologic development, fashionable 3 water-line, low minimum hull weight and performance . Conrad ‘s approach to a continuing development of FD, with regard to materials, fitting and rigging evolution, was basic for the FD success. -

Survival Rates of Russian Woodcocks

E-mail: [email protected] We analysed 324 recoveries from 2,817 Russian Woodcocks ringed as adult or yearling in two areas in Russia (Moscow and St Petersburg). We suspected that birds belonging to these two areas may experience different hunting pressure or climatic conditions, and thus exhibit different demographic parameters. To test this hypothesis, we analysed spatial and temporal distribution of recoveries, and performed a ringing-recovery analysis to estimate possible survival differences between these two areas. We used methods developed by Brownie et al. in 1985. We found differences in temporal variations of the age ratio between the two ringing areas. -
What's So Great About Sailing the Gorge?
What’s So Great About Sailing the Gorge? Bill Symes & Jonathan McKee Seattle native Jonathan McKee was one of the early pioneers of dinghy sailing in the Gorge. His accomplishments include two Olympic medals (Flying Dutchman gold in 1984, and 49er bronze in 2000), seven world championships in various classes, and two Americas Cup challenges. CGRA’s Bill Symes caught up with Jonathan to find out why he likes sailing in the Gorge. What makes the Gorge a special place to sail? It is really one of the legendary venues of the world. But it’s not really in the classic model because the local sailing community created it from scratch. It’s a pretty unique situation; it still has that home-grown feel to it, sort of a low key aspect which is different from sailing in San Francisco or someplace like that. It’s all about having a good time and enjoying the beautiful place that it is. But at the same time, there is consistently a very high level of race management. So even though the vibe is pretty relaxed, that doesn’t mean we don’t have really great racing. The focus is on the sailing. And, of course, getting better at sailing in stronger winds! That’s one thing the Gorge is uniquely suited for. How does this compare to other heavy air venues? It’s a low risk way to get better at strong wind sailing. A lot of the windy places are either not windy all the time or so windy that they’re really intimidating. -

ABSTRACT (Maximum 200 woras) The purpose of this project was to study porpoising, one of the most common forms of dynamic instability found in planing boats. In descriptive terms, it is a coupled oscillation in pitch and heave that occurs in relatively calm water. These oscillations can be divergent in amplitude, leading to loss of control, injury to occupants or damage to the craft. The mechanics of porpoising have been studied sporadically from theoretical and experimental perspectives for many years. -
