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?

Here's a real flying car [timesonline.co.uk]. 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 :)

From the times article:

Re:Terrafugia? I don't think so.

Drag your wings behind you??? Have you even looked at their prototype?

Before you start making stupid comments, check your facts. The Terrafugia folds it's wings vertically. They are folded electrically, so you don't have to even get out of the car. In fact, you land at an airport and before you even get off the taxi-way, the wings are folded.

BTW... I just chatted with Carl the other day and they are getting ready to start flight testing. They're just waiting for their final signoff for their airworthy certificate. They've have driven it up to 70 mph so far.

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!)
