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 ...
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 says fly-size ornithopters should be possible, provided the tail is well designed. Rick Ruijsink of TU Delft cites battery weight as the biggest problem; the lithium-ion battery in the DelFly micro, at one gram, constitutes a third of the weight. Luckily, developments in this area are still going very fast, due to the demand in various other ...
The Snowbird is a human-powered ornithopter that was built as a project of the University of Toronto Institute for Aerospace Studies (UTIAS). Snowbird was the first human-powered ornithopter to fly straight and level. [1] [2]
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.
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.
In late November, news reports surfaced that OpenAI researchers may have made a breakthrough in creating AI software that could learn to solve grade school mathematics problems it had not seen ...
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.
