Amazon's idea of employing drones to deliver packages to your doorstep might not be so far-fetched after all if the latest viral video is to be believed.
No, it's far fetched. Have you ever heard of the FAA? Do you know what a "TCA" (terminal control area) is.
Military "drones" should be capable of lifting a model. But, those are fixed wing aircraft. As such, they would be markedly unsuitable for STOL on your average city streets.
Now, if you want to "surface to ground" a package through the customers front window, liability be damned, a loitering drone would be a worthy launch platform.
Then, all Amazon would need is local "spotters", to light up the customer's house with a LASER.
If anybody cares, military "Harriers", are normally launched from a runway. British aircraft carriers have a "ski jump", type addition to the end of the deck. Why? Because launching a Harrier vertically, is massively "fuelish"!
Helicopters have some of the lowest hourly service intervals in all of aviation. The smaller an engine is, the shorter time to a complete teardown. For example, "Rotax" two stroke engines, which are used in ultra light aircraft, (and in snowmobiles), have a 200 hour to tear down permitted service interval.
Even the Lycoming and Continental piston engines in standard light planes, are only 2000 hours to tear down.
So, (IMHO, of course), your video is a fake, and Amazon's CEO, is talking out his A**.
I think a few of you are going to be eating humble Pie I say very real .. also don't go by the size or diameter of the motor alone to say if it has the power to lift a person .. there are a lot of variables here. the weight of the person the batteries used the motor / gearing and the blades. each blade is 700mm if not bigger couldn't tell but when you do the math your talking about two 4.5 foot disk lifting someone.. I own a heli 600 size helis and im sure two can do the job to pull and lift someone ..of course within a reasonable weight.
Dude, if the batteries go dead in 40 seconds, the helo(s) in question couldn't possibly travel any distance with "XX" cargo. You'd need to run an extension cord from your friendly local power substation, ,to keep it airborne for any length of time.
So realistically, this whole story is reminiscent of, "the woman who lifted an automobile of of her child". Yeah, it can be done, but not for very long.
You might be the one having pie with dinner this evening.
Once upon a time, one of these would go ungodly fast, and pull an ungodly amount of freight. Crank down those pantographs, or forget to pay the electric bill, you got yourself the world's largest paperweight.
So I know "now all we have to do is design more efficient batteries", "the better mousetrap", or ask the Romulans if they'd be willing to share the singularity technology which powers their warp drives with us..
