More recent vehicles, such as the human-powered ornithopters of Lippisch (1929) and Emiel Hartman (1959), were capable powered gliders but required a towing vehicle in order to take off and may not have been capable of generating sufficient lift for sustained flight. Hartman's ornithopter lacked the theoretical background of others based on the ...
An ornithopter (from Greek roots ornithos-[35] "bird" and pteron "wing" [36]) is an aircraft that flies by flapping its wings. In the Dune universe, ornithopters (or ' thopters ) are one of the primary modes of transportation on Arrakis.
[3] [4] Since that time, many people have tried to make human-powered flight like a bird happen. [ 3 ] [ 5 ] In 1991, the Fédération Aéronautique Internationale (FAI) awarded a “Diplôme d’Honneur” for the first remotely operated engine-powered ornithopter, which was developed by Professor James DeLaurier and UTIAS .
The DelFly project started in 2005 as a Design Synthesis Exercise for a group of Bachelor of Science students at the Faculty of Aerospace Engineering of the TU Delft.The flapping wing design was mentored by Wageningen University, [3] the remote control and micro camera integration by Ruijsink Dynamic Engineering, and the real-time image processing by the TU Delft.

He also identified and described the importance of dihedral, diagonal bracing and drag reduction, and contributed to the understanding and design of ornithopters and parachutes. [2] Another significant invention was the tension-spoked wheel, which he devised in order to create a light, strong wheel for aircraft undercarriage.
From the last years of the 15th century onwards, Leonardo wrote about and sketched many designs for flying machines and mechanisms, including ornithopters, fixed-wing gliders, rotorcraft and parachutes. His early designs were man-powered types including rotorcraft and ornithopters (improving on Bacon's proposal by adding a stabilizing tail). [26]
Diagram of the ornithopter design from the patent application. The wedge-shaped objects on the wings (#20) consist of the fabric "valves" (#21), which would blow closed against the supports (#20) on the downstroke. Caldwell then turned to an even more bizarre aircraft design, an ornithopter.
John Joseph Montgomery (February 15, 1858 – October 31, 1911) was an American inventor, physicist, engineer, and professor at Santa Clara University in Santa Clara, California, who is best known for his invention of controlled heavier-than-air flying machines.
