Aviation history Part 2 (The flight dynamics and the principle of "heavier than air")

The many attempts to imitate the flight of birds, had all failed, is too complex, so that the easy and effortless movement in search of birds in "six degrees of freedom" which is technically expressed physically Actually: The free flight allows three directions of motion in the horizontal and vertical planes and three rotational movements about the longitudinal, transverse and vertical. The domain of the six degrees of freedom makes so fascinating, but also, along with the production of lift and thrust in like flies, as problematic.

The English scientist Sir George Cayley drew about 1,809 in the right way. He separated the basics of flight - in three separate tasks, and did a basic outline of the aircraft, in the example - lift, propulsion and control surfaces are back control. However, numerous attempts in the 19th century were still without success (Stringfellow, Henson, Wenham and Maxim in England, Le Bris, du Temple, Penaud and vein in France; Mozhaiski in Russia).

Progress on the slider managed Otto Lilienthal (1848-1896). From 1891 until his fatal accident August 9, 1896, scored with the constant improvement of more than 2000Gleitflüge monoplane and biplane. Lilienthal had at the School of Commerce (now University) in Berlin to enjoy one of the most renowned scientists in engineering (Franz Reuleaux) with a sound engineering background, was the leakage problem according to a systematic and addressed scientific and experimental. Unlike in England (Pilcher), France (Ferber) and the U.S. (Wright) were observed in Germany, his little progress.
