Welcome to War and Tactics!    War and Tactics Forum is currently undergoing some modifications that might disable features you are used to. This is unabvoidable as we have to update the forum engine to a new structure that is incompatible with many of the features we had used so far. The good news: WaT will be more secure and stable, and most of the features we uninstalled will be a natural part of the new structure anyway. For the rest we will be looking for solutions.

For the first time ever an ornithopter driven by manpower managed a sutained leel flight of around 20 seconds (an ornithopter is an airplane that moves by flapping its wings) thus finally realizing something close to Daedalus´ and Leonardo DaVincis dream.

Up to now it was almost impossible to built a man muscle powered ornithopter because of the bad weight/power ratio.

Here the vid, amazing sight, and lots of high tech involved (the whole bird weighs only 42 kilos at that amazing size):

While it did not auto-start (this is still considered rather impossible) it flew level and held the height for 16 flaps and only descended when the pilot stopped flapping.

The bird was constructed by a group at the university of Toronto and had a wingspan of 32 metres made out of carbon fibre, balsa and foam. The pilot sits in a small cockpit suspended below the wings and pumps a bar with his feet to operate a system of wires that flap the wings up and down. The pilot steers using a pair of metal bars attached to rudders on the back of the aircraft. Towed by a car until airborne, it then sustained 19.3 seconds of flight, over a distance of 145 metres; an average speed of 15.91 miles per hour. Although similar tow-launched flights have been made in the past, improved data collection was used to verify that the ornithopter was capable of self-powered flight once aloft.
