Lilienthal, Otto

(ô`tō lē`lyəntäl), 1848–96, German aeronautical engineer, a pioneer in his experiments with glidersglider,
type of aircraft resembling an airplane but having at most a small auxiliary propulsion plant and usually no means of propulsion at all. The typical modern glider has very slender wings and a streamlined body.

. He made major developments in the glider based on his observations of birds and wrote a number of books on aviation. His brother, Gustav Lilienthal, 1849–1933, was associated with Otto in his flying experiments and continued them after his brother's death.

Lilienthal, Otto

 

Born May 23, 1848, in Anklam; died Aug. 9, 1896, in Berlin. German engineer; pioneer in aviation.

Lilienthal completed many flights on gliders that he designed himself. He came to the conclusion that, all other conditions being equal, a wing with a concave profile provides more lift than a flat wing. He proved by experiments that the magnitude of lifting force of wings varies with the change in their angle of attack. For this reason, the correlation diagram between the frontal resistance coefficient and the lift coefficient of an aircraft has been named after Lilienthal—that is, the Lilienthal polar. He offered an explanation of the factors involved in the gliding of birds (”The Flight of Birds as a Basis for Aviation,” 1889). He was killed near the town of Steglitz (near Berlin) during a flight from Mount Rinower. N. E. Zhukovskii valued Lilienthal’s experiments highly.

An introductory chapter reminds us of the important attainments of such 19th Century experimenters as Sir George Cayley, Otto Lillienthal, Octave Chanute, and the Wrights as well as other less successful pioneers; but the major thrust of the volume comes with the 1917 founding of the National Advisory Committee for Aeronautics (NACA) with its facilities for basic research into aerodynamic, structural, and propulsion problems.
This well-written story puts flesh and blood on the early pioneers of aviation, including Glenn Curtiss, Otto Lillienthal, Samuel Langley, and of course, Orville and Wilbur Wright.
