Not getting my hopes up. These are the reason I didn't bother to learn to drive, forty farkin' years ago.

It would only be a matter of time before the sky is full of assholes leaving their turn signals on, texting while jetting, etc.

People have enough problems in 2 dimensions, they really don't need to add a 3rd.  Can you imagine seeing the "Student Driver" sign on a flying car (or a jet pack flier?)
 
2013-08-18 12:08:13 AM  
Nope. People cannot drive vehicles without farking it up. No way are we ready to let ordinary joes fly a jet pack around. That'd require new laws. Sorry to burst your bubble.

THIS. I have yet to see many other people even make a left turn correctly, let alone fly a jetpack.

(the correct way to turn left at an intersection is to pull up when the light is green, await your chance, and TURN left... Not to wait behind the line when the light turns gree, and then ANGLE/SLANT left, veering partway into the other lane or middle oncoming lane when you're doing it.)

Oh, and when your engine quits on the road, you probably won't die. If your jetpack engine quits while you're in the air, you can kiss your ass goodbye.

If there are jetpacks in 2014, does this mean we get hoverboards in 2015?

From what I remember (and it's been a while since I last read about these things) the "jetpacks" qualify as ultralights, so no license is required.

If you live 8000 or less feet from your work, you don't HAVE a commute.  You have a brisk 20 minute walk.

Not claiming to be an engineer, but if the thing can't glide, (and it can't) it should need (nearly?) as much downward thrust going horizontal as vertical.  It probably goes farther on the parachute than on the actual jets.

I think altitude will depend on engine power and fan efficiency which is a factor of altitude, temperature, etc.

So at 8,000 feet the power of the engine and fan efficiency is not to sustain level flight.

It doesn't get to 8000 feet and then run out of fuel, it gets to 8000 feet and then continues at 8000 feet for about 32 miles, Just think of it like it's a very small, two bladed helicopter.  It can do everything a helicopter can do.  Well, it probably can't rotate in place as quickly, but that's not the point.  It maneuvers in a very similar manner.

Where are you seeing that?  The article says "the jet pack can almost a mile high" (5280 feet) and that "it can probably move about 8,000 feet."

That's poor wording, but it clarified by the remainder of the sentence "We reckon it can probably move about 8,000 feet, but we don't think many people will want to go much higher than that, particularly when they're strapped into this machine,"

When he says "move," he is referring to the operational ceiling.

I got the range by Googling "Martin jetpack range," which returned 32 miles.  However, the company's site itself states 30km, which is significantly less:

So no engine out capability, got it.

And if you lose just ONE engine, or if it tips over on takeoff or landing, you are now strapped to a giant one of these:

Um it doesn't work like that. People who do not have the skill required are never allowed to solo. My CFI had one person who had over 50 hours and he still never would allow him to solo.

I don't see that's necessarily true. If it has the intelligence of a cell phone it should be able to throttle down the running engine if single engine capabilities are terrible, and throttle down both engines if it tips over, at which point you are relying on your ballistic parachute.

Came to make sure this was said. When people say jetpack, they mean jetpack. Hot or pressurized air or liquid must be forced through a nozzle to push it off the ground and propel it forwards. This is like referring to a paddleboat as a torpedo.

Tell that to a few friends of mine from college, with pilots licenses, who I wouldn't trust to operate a mechanical pencil, much less a plane.  Why yes, two of them crashed their cars while drunk (their parents were just SO proud).  Why do you ask?

I think the problem was their rig was too heavy. 65 horsepower ought to be plenty to get a human airborne. But then, they were testing whether you could build a personal VTOL using plans ordered from the back of a magazine. If they'd had a custom-built powerplant and a carbon-fibre frame it might have gone differently.

Looks like these guys are using a 2.0 litre V4 piston 200-horsepower gasoline for their JetPack.


I have a hard enough time puttering around horizontally in the pattern in a Cessna 152 with 108 hp.


Flying vertically on a 65 hp engine might be hard to manage for my 220 pound frame but it would be interesting to see someone pull that off.

Not that much to do with getting shot at.
Its the cost, complexity, limited flight time, and skills needed to pilot them that ultimately curbed the militaries interest.
They did manage to solve two of those problems around the time Helicopters became better at filling the transportation niche.

/they did not resolve the problem of enemies shooting at low flying things, however.
/the difference now is that you lose twenty men instead of just one.
