The REAL HAYABUSA FALCON 242 mph!

That bird is amazing. I hope in trying to push it, he doesn't hurt the bird. The forces at 180+ are tremendous. Glad the bird did ok on both tests. Stunning video!
 
Terminal velocity or what some are calling "free fall" only pertains to when the drag equals the downward force of gravity - changing aerodynamics changes the spped as the force of drag is lowered. :thumbsup: GO BIRD!!

On a side note...I don't think my Quaker Parrot "Hoover" can get over 24.2 mph let alone 242! Then again, I bet the falcon can't ask me "whattaya doin" :laugh: although he could EAT my parrot. :lol:

Based on wind resistance, for example, the terminal velocity of a skydiver in a free-fall position with a semi-closed parachute is about 195 km/h (120 mph or 55 m/s).[2] This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on. Higher speeds can be attained if the skydiver pulls in his limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] which is also the terminal velocity of the peregrine falcon diving down on its prey.[3] And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards, or perhaps just dropped from a tower — according to a 1920 U.S. Army Ordinance study.

Interesting that the study done here makes references to the peregrin falcon's terminal velocity as being the same as that of a tucked in human sky diver. The shape of the hayabusa has been molded and perfected through tens of thousands of years of evolution for 1 single purpose, even it's feathers are designed to reduce drag (it is probably more efficient at reducing air turbulance than the "dimpled tape", we just can't replicated it yet) . The video stated clocked speed of the hayabusa at 242 mph sounds more believeable than stated in this quote.
 
that was pretty rad. 242 mph, holy crap. isn't terminal velocity something like 130 mph?
 
If you've ever seen a Peregrine, they're pretty small birds. About 1.75 pounds at the heaviest. That it can dive at any speed is an aerodynamic/physics mind-blower. Fantastic.

As for not being propeled...really, dude?
 
Fantastic video. National Geographic never ceases to amaze.

I think the bird should have been named "Fearless"... :laugh:
 
Only one way to find out for shure. Who wants to drop their bike out of a plane? I hear the genII's are more areodynamic with the rider on.:laugh:
 
Good thing HD doesnt make a bike called "Hayabusa"...
The chrome plating might help the aero's, but that bird could NEVER have attained 242 with the leather streamers, plus its beak woulda vibrated off anyway...

:laugh:

(Im just sayin...)
