"Of all the men who attacked the flying problem in the 19th century, Otto Lilienthal was easily the most important. His greatness appeared in every phase of the problem. No one equaled him in power to draw new recruits to the cause; no one equaled him in fullness and dearness of understanding of the principles of flight; no one did so much to convince the world of the advantages of curved wing surfaces; and no one did so much to transfer the problem of human flight to the open air where it belonged."These words were spoken by Wilbur Wright, who successfully accomplished the first powered flight together with his brother Orville in 1903 on the sand dunes of the Outer Banks off the coast of North Carolina. Wilbur was talking about the most important of their predecessors, Otto Lilienthal.Lilienthal attracted worldwide attention due to the spectacular photographs showing him in flight, made possible by technology that had only just been developed by him. This fortuitousunion between a pioneer of aviation and the pioneers of so-called ¿instantaneous photography¿ is responsible for the immense contemporary popularity of Lilienthal¿s flights around the globe, the first ever free flights performed by man. This book traces the life of the German aviation pioneer, focusing on the designs of his many aircraft and the photographic documentation that has survived. The presentation ends with a remarkable research project conducted by one of the authors, right up to and including his own training exercises with Lilienthal¿s ¿normal soaring apparatus¿ and ¿large biplane¿. This project offered new insight into Lilienthal¿s work, and also led to a spectacular aerial meeting of Lilienthal's 1895 biplane and the Wright brothers¿ 1902 biplane at a historic location on the Outer Banks. The book provides access to video material, largely stemming from this project.

This immensely practical guide to PIV provides a condensed, yet exhaustive guide to most of the information needed for experiments employing the technique. What's more, the huge increase in the range of possible applications has been taken into account as the chapter describing these applications of the PIV technique has been expanded.
