Pentagon Clears Flying-Car Project For Takeoff

unassimilatible writes "DARPA has announced a 'Personal Air Vehicle Technology' project. It will 'ultimately lead to a working prototype of a military-suitable flying car — a two- or four-passenger vehicle that can "drive on roads" one minute and take off like a helicopter the next. The hybrid machine would be perfect for "urban scouting," casualty evacuation and commando-delivery missions, the agency believes.' Wired has the summary of the project." Maybe they'll take inspiration from Terrafugia's "drivable airplane."

Will 80 mph do?

[jmichaelg]

Here's a real flying car. At 80mph, it doesn't have the airspeed that DARPA is looking for but it does hit all the other check items and supposedly it's easy to fly.

The downside is that it's LOUD as heck, since it uses the fan for propulsion while on the ground.

Apparently not:

"The fan's static when you're driving around," says Cardozo. "The engineering challenge was getting a really reliable system that will switch power between wheels or fan."

That is by far the coolest flying car I've ever seen. It takes off at only 35 MPH, would be relatively cheap, and looks like it would have great off-road mobility in car mode. Only problem is I couldn't find it on youtube, so I hope it's in the new Bond movie :)

Hard to evacuate soldiers in a one-person dune buggy that needs to take off horizontally with a 'shute that tangles on street rubble and powerlines.

Oh, but I still want one.

Except that you won't catch me flying a para-car, the disadvantages are many.

PLUS:
~) it's cheap; fairly easy to implement.

MINUS:
~) Parawings have a tendency to fold when you turn too sharply.
~) It does poorly in windy conditions.
~) Slow, inefficient, high drag.
~) Tendency to "rip".
~) Takeoff is difficult.
~) An in-flight rainstorm is a once-in-a-lifetime experience, by definition.
~) Poor handling in engine-out / emergency circumstances.

I'll pass, thanks! Even as a VFR pilot, I've flown in rain many times, and at 150 MPH, it happens surprisingly quickly... I can only imagine what the power-fail glide slope is on something like this. (7:1 for a Piston Cessna, as high as 20:1 for jets, often as poor as 2:1 for an ultralight/paraglider - you sink like a STONE when the power goes out!)

It's amazing what weirdo's with a bunch of money can do http://en.wikipedia.org/wiki/Hughes_H-4_Hercules
This one will probably turn out to be as useful but at least someone is trying!!! Too bad it's with my money this time.

Re: How far does it have to fly?

With enough explosives altitude won't be a problem but distance and landing may be an issue.

Flat screens, too...

[Ungrounded Lightning]

I've been reading since the early '50s about the imminent personal flying craft and similar wonders in such august publications as PopSci, Popular Mechanics, etc. I grow weary.

Yeah.

But I've also been reading about flat TV screens for as long, too. (They had a cute one back then: Neon switches, crosspoint matrix, electroluminescent elements at the crosspoints for scan, then transparent conductor, opaque light-controlled-resistor, and another layer of electroluminescent matterial for the screen light source. Plastic "circuit board" so you could wrap it around a pencil.)

It took 'em half a century to get (several types of) TV quality flat screens. And they're all STILL more expensive than CRTs. (Maybe now that the LCD price fixing conspiracy is broken that will FINALLY change.)

Ditto "dynabook". Ditto microscopic robots - some circulating in the blood stream - for microsurgery and/or immune system assist against diseases. Ditto cloned replacement teeth. Ditto age-retarding-or-reversing drugs.

A lot of stuff is FINALLY STARTING to happen. But I've been waiting a LONG time for it. And at this rate maybe I'll get to see prototypes of some of it by the time I retire, but still won't get the benefit of playing with the toys. B-(

Re:No one on Moller yet?

[Egotistical Rant]

I remember reading about Moller's Skycar in Popular Science when I was a kid...about 30 years ago. It's a pretty well-documented fraud now.
