Non-steady state aerodynamics of flapping flight. Rather for aerospace engineers but in my eyes interesting...

when physics comes into public debate... of high interest!!!

soon the ball may look like a golf ball ... better aero.

A bad workman blames his tools... P.S. Polish version of this proverb is much nicer, and says that poor ballet dancer blames her skirt... but it's nothing compared to the Russian version, which says about a male ballet dancer who blames his... well, guess yourselves...

the Alaskan bar-tailed godwit (Limosa lapponica baueri) (Figure 1), makes its eight-day, 11,000-km autumn migration from Alaska to New Zealand in one step, with no stopovers to rest or refuel. This roughly doubles the previous maximum direct flight distance in birds, challenging experts to square this remarkable marathon migration with our understanding of aerodynamic theory and endurance physiology.

The dragonfly wings as discussed during the Bremen KO meeting. There should also be some cool videos and CFD stuff visualizing how this actually works.

The researchers have created two-dimensional computer models of the flying snakes, but they've also done real-world simulations - using 3D printed components in water tunnels. Both show that snake-shaped objects would get a special aerodynamic pop should they tilt their bodies at 35 degrees as they drop from tree branches.

what a ACT's exercise should look like...

Maybe, you should propose this exercise to the team. You'll see there is not much imagination, unless, you consider imagination equals craziness (bullshit things ... and the too common blah blah in the act). I think this concept is an imaginative credible concept. "anything we might ever see" explains it well.

well, the article is not very detailed so it can be only "du vent" ! did they actually try if such an airplane can fly ??? what about the engine ??? i find the solar impulse (see post below) much more eco-friendly !!! I agree with Leopold that it's quite boring and stays in the mainstream of the production. I'm sure we can do much better !!! What about some really useful things like pills against the flight sickness, and some really good food in the plane ? haha not soon to happen with all the cost reduction. The future of air transport will be a plane without seats, stewards and perhaps even without pilot !!!

As usual, the Army does it...

A free software tool that could revolutionize the drone industry to design and build your own drone/aircraft/fighter with a 3-D online software that generates aerodynamic information (maybe optimization also) about your own design.
