Another Ornithopter Takes Off 166
mnmn writes "Ornithopters have been around for a while, but a professor at the Toronto Institute for Aerospace Studies has made progress with his. It flew for 14 seconds and covered a third of a kilometer. However it landed with a bit of a crash. Interestingly it uses a glow jet turbine from RC aircraft."

Congrats. Of course, the signal to noise ratio is still painfully small. But it's a start.

Nobody should stop dreaming though, they should open a donation page and print names on the wings!

Manned Ornithopter Flight Already Done (Score:4, Interesting)
Incidentally, you can buy some pretty neat ornithopter kits from www.ornithopter.org [ornithopter.org]. I'm not affiliated or anything, just interested in flapping-wing flight and experimenting on a small scale.
The development of flapping wing flight is interesting because it can also have other applications. I am especially interested in the use of 'flapper' designs in water craft (specifically for use in robotics). An interesting use of similar tech can be seen in these kayaks [hobiecat.com]. Intersting stuff.

Basically, white meat stays white because farmers clip their chickens' wings to keep them from exercising those muscles much.
The more a muscles is exercised, the darker the meat gets.

There's a project [psu.edu] at Boeing to create a hummingbird-like propulsion system. It says, "Flapping flight may be the wave of the future for aviation." Their system relies on a shape-memory-metal actuator muscle. I'm forgetting at the moment who but there was another group recently that had a big announcement about simulating muscle with shape memory metal systems.
Obviously this is still R&D, but flapping doesn't seem to be down and out just yet. (BTW, I looked it up and a hummingbird wing is just shy of 180 degree rotation with 75% of the lift from the downstroke and 25% of the lift from the upstroke). Energy consumption is high, so portable fusion generators might be a necessary prerequisite for heavy craft.
