Somebody is going to be gored by a drone, and it will be horrible.

(On the other hand, someone else will get a taco delivered to them by a drone while they are flying and it will be sublime.)

As discussed in the comments...the symmetrical design is horrifying. When one engine goes out, you are in a spiraling tornado to the ground. But as a technology, cool, if you want to fly for 10 minutes...then refuel...all Jetsons love to you.

You stash the spare fuel in the trunk of the flying car.

I'm more worried about leg burn. The exhaust gas temperature of those types of turbines is usually hot enough to melt aluminum! [pdf]

Non-issue. Just cut the other engine and plummet normally.

I'd love to hear the 911 calls placed by people on boats in the harbor.

This bit is scary:
In terms of performance, the JB-9 will fly for at least 10 minutes before running out of fuel, with its specific endurance dependent on how much the pilot weighs. Top speed of the JB-9 is about 100 kilometers per hour, with a climb rate of between 150 and 300 meters per minute. Both the speed and climb rates will increase as fuel is burned off. Jetpack Aviation speculates that you'd have no trouble hitting 10,000 feet.
You could "hit" 10,000 feet (just over 3,000 meters or three kilometers) by flying directly up for ten minutes, at which point you would run out of fuel. Yes, you would hit 10,000 feet, but from the wrong direction.

This fills me with a childlike delight. I know it's still probably not practical and has issues but they do nothing to ameliorate my childlike delight one bit.

You climb to 10,000 feet and take a parachute down, right?

So... Where do I put in my credit card number? Because that was awesome as all get out. The helmet camera footage reminded me of flying the helicopter a few feet off the water in GTA IV.

As one who has spectaculary crashed a quadcopter due to orientation error, I'll let the rest of you do the jetpacking.

Add an emergency parachute and increase flight time to 1 hour, and I'm in!

It appears to have some kind of rollcage at the top and back? That's an accessory science fiction seems not to have foreseen.

A few years ago I read this book about a few guys a few minutes drive from where I'm sitting who decided to build their own rocketbelt. They succeeded, but also ended up in jail, kidnapped, or murdered. A typical Texas mess.

Jetpack Aviation speculates that you'd have no trouble hitting 10,000 feet.

Minus the, you know, certification and pilot training, safety devices of any kind, lights, transponders... Especially in and around some of the busiest and most complicated airspace in the world. Do you remember how a teeny tiny little bird took an airliner down into the Hudson? Imagine what happens when some schmuck with one of these decides to see if he can race a 777 on departure from JFK.

The closest current analog we have to someone flying something like this is skydiving operations. However, skydiving happens at fixed locations that are clearly marked on aviation charts to provide pilots the information necessary to be cautious. Air traffic control announces when skydiving is happening if those locations fall within their areas of control. Jetpack enthusiasts currently would need to operate in the same way in order to ensure safety.

Flying around New York City is tons of fun but also can be very dangerous. Small aircraft are transiting the area over the rivers at very low altitudes - airplanes flying up the Hudson are only at about 1,000 feet, and helicopters are going to be even lower. And as has been shown previously, it's really hard to see small aircraft and it would be even harder to visually identify someone flying around on a jetpack.

So let’s do a quick back-of-the-envelope guesstimation. Getting all the pieces to work together like they should certainly took a lot of time, testing, and experience on Jetpack Aviation’s part, and we're not trying to minimize that in the least. But, the most expensive parts seem like they have to be the engines.

They are completely missing the point that, by far, the biggest cost for any new aviation product is the integration. Parts are literally orders of magnitude cheaper.

Also, over the whole lifecycle of an air vehicle, the biggest cost (again, orders of magnitude over integration) is sustainment. Jet engines are not cheap to maintain. And, you know, these R/C engines aren't certified in any meaningful way and probably can't be without significant effort and cost.

And whatever happened to the autocar? No really, I'd seen the address of their headquarters and drove by when it was on the way, oh, sec, here's the google map. Well not exactly, but quite literally in a garage!

It's actually quite exciting charming cute(?) that folks are still building super science devices basically in their garage, even when physics, law, social norms, rationality are all conspiring against success.

A quick 8 minute dash well above and over traffic really could be handy at times! Park out of the way break out the pack, make that appointment in style!

Hmm. I'm not seeing the practicality of this until they put in a tiny nuclear reactor instead of fuel.

Actually, wait a minute. Ten minutes of flight could give us about 12-15 miles of range. That would be enough to cross the Mexican border- what's the weight capacity?
posted by happyroach at 8:59 AM on November 16, 2015


Ten minutes might be long enough to make this interesting to the military. And the CIA probably already has some batshit plans for it.

I don't see these ever being sold to private individuals, and it would only take a whiff of fear mongering to convince the public to go along with a ban.

Legit question: four quadrocopters + some kind of robust fabric = magic carpet? How powerful do we need these devices and materials to be to make this happen?

You just need a 100lb propane tank on wheels and 1000ft of hose. Easy peasy.

> Legit question:

Ever hang up a hammock? The force required to keep a carpet taut enough to ride on would be enormous. You'd be better off nailing your quadcopters to a sheet of plywood.

That said, electric multicopters strong enough for manned flight are already a thing. There's at least one company making an all electric prototype multicopter based on hobbyist parts and batteries. It has something like 20+ fairly large rotors, in 1-2 foot range.

The design has a lot of benefits. More rotors means it's less likely that you'll simply plummet to the ground if you lose a couple of rotors.
