Der Vogelflug als Grundlage der Fliegekunst
 Ein Beitrag zur Systematik der Flugtechnik

by Otto Lilienthal

"Der Vogelflug als Grundlage der Fliegekunst" by Otto Lilienthal is a scientific publication written in the late 19th century. The book explores the mechanics and principles behind avian flight, drawing from extensive experimentation conducted by the author and his brother. It aims to unveil the various factors that enable birds to fly and hopes to inspire further study into human flight. The opening of the text sets the stage for the exploration of flight mechanics, emphasizing the lack of understanding in the scientific community about the principles of flying. Lilienthal expresses a deep-seated desire to understand how birds achieve their aerial feats, suggesting that through careful study of nature, humans may one day master the art of flight. He introduces the fundamental mechanics at play, discussing the forces involved, particularly air resistance and lift, and expresses hope that both professionals and interested laymen will delve into his findings, fostering a broader understanding of the principles of flight.
