Combine it with a Segway while you're at it.

interesting that is original design was a BI rotor, but he switched to quads.
my guess is that it was for stability and additional lift and safety

Definitely would like to try this. Looks cooler than a Segway by far
 
2014-08-21 06:38:55 AM
Too much damned noise, like all drones.  Still, hope it works out, would love to try it.

OK That looks awesome but if it were a reality it would have somepretty hefty restrictions on the use of it get ready for a nightmare getting each individual country to make them legal.

And:
Moron drivers are bad enough, placing people in the air on less stable flying contraptions will only amplify the problem..

But think of the benefits to society in culling the "hold my beer, Bubba. I wanna try somethin'!" crowd. These could be better than ATVs.

Especially when they crash down on the nun pushing a baby carriage out of the cancer ward of the children's hospital to tell the parents that their daughter will live a long healthy life.

While it sounds good in practice, these people are going to have less boundaries and will be falling on top of people like us.  A car plowing through a farmer's market does just that, plow.  Some broken legs and some ruined vegetation.

When one of these things comes down on a person, it is going to turn them into mincemeat.

We have a hard enough time looking out for morons on the ground, and with a threat from above, our own risk grows two fold.

Battery duration would be the stumbling block here. I don't imagine the manned version  getting more than ten-fifteen minutes in the air.

  The over/under overlap of the rotors keeps the overall size down, while giving more stability in roll. Having one set of blades overlap the other will make it louder in flight, and may reduce efficiency a bit due to turbulent flow into the lower rotor, but he must figure the trade-off for stability is worth it.

The bi-rotor fore-aft  design has a critical angle in roll, beyond which you can't recover without trying to complete the roll.  That's dangerous at low altitudes. Close-coupled quad rotors give you more roll authority to resist rolling too far over.

It'll be like that level in battletoads....

They could also get killed by a de-orbiting satellite. What's life without a little risk?

His (?) idea to use the shrouds as engine mounts creates an awesome visual effect.  I'd copy it if I were building an arduino RC version.

I don't know about building one but you can buy the RC version.http://www.hover-bike.com/MA/product/drone-3/

...and redone, and redone, and redone.

They're long overdue to just build a real one already.

Does the thing look anything like this one?

Quad fans instead of dual fans, but otherwise yes.

Cool proof of concept, but just like jetpacks, anything that's man sized just requires too much power to stay in the air for long enough with current battery/engine tech.

Dyson bladeless fans, and Segway gyroscope and autoleveler.

Better add a ballistic recovery 'chute to it while they're at it.

/more weight = less flight time

It's an evolution of that one.

That's not entirely the case tho. 
Both the X-Jet and the Martin Jetpack (and, if I recall, the solo-trek) boasted of half hour long flights. They were also unoptimized prototypes. 

/The physics are sound and the technology can do the job, but no one's put serious effort into designing a jetpack.
/Its always some back yard mechanic with a bunch of motors he found lying around.

Two points define a line. His original produced an axis of thrust.
Three points define a plane. Perfect if you want to place your camera somewhere.
Four points define a surface. And if he has individual blade control then he can warp the surface of a thrust vector to produce all his motions without vanes and ducts.

X-Jet is tethered so it's technically not a true jetpack, there you can fly unlimited time as long as someone else is pumping your water.

The Martin Jetpack is much better, 30 minutes really isn't bad, but that is a very optimized product at this point.

Seems like a really bad idea.

My bad, I should have specified the Williams X-jet.

The Martin product is still very young where the Solo-Trek was rumored to have four times the range using a similar setup.
They should be able to get another hour or two out of it with some advancement.

Going beyond that, there's been a number of VTOL transports proposed and flown over the years. Each had varying degrees of success, but many showed stability and useful range.

Problem being that its very difficult and expensive to develop an entirely new kind of aircraft, and the market just hasn't responded the way you'd expect when someone says they've got a flying car.
 Its not really a physics or engineering problem so much as a bureaucracy and marketing problem. 

What the FAA doesn't stall is killed by lack of interest.

Yea but nobody's actually introduced a flying car yet. The vehicles that have made it to market are all either light airplanes that have detachable wings and are terrible cars or some some variations on the helicopter which are too difficult for the average person to fly. No "flying car" yet available had approached the reliability or ease of use of the automobile which is the whole point of wanting a flying car.

That looks like fun, even for only 10 or 15 minutes.

Johnsnownw: Seems like a really bad idea.


yeah - I think they said it was a 1/3 sized prototype, but they also said it was designed to go up to 9,000 feet.  That's insane.  You're going to need some sort of 5 point buckle system so you don't fall off and what's going to happen if you turn too sharply.  I'm guessing you'll drop like a rock.

Something like this would be cool to go pick up groceries with, but there's no place to put the groceries.  I could get to a grocery store without going higher than 50 feet as well - maybe up it to 100 just to be sure but I would not want to fly in one in bad weather.
