It's the latest Electric Tethered Observation Platform from Israel Aerospace Industries, photographed at the Paris Air Show, according to km2804.
Basically a long camera boom, as shown in this earlier concept image:
And this is a human version
A big AR.drone, pretty.
Shrouding is more than trendy, it is efficient (payload) and secure. Tough in this version, the rather straight shroud wall is not birnging much added thrust. The 160x160 centimeters size means large triblades, producing 5kgf each.
They do exist today, can cite 2:
MARTIN jetpack: A personal bi ducted fan (reached 5000ft in May 2011 unmanned, before assessing the overall security, parachute equipped).
MOLLER SkyCar and Jetson quad ducted fan
there was also a design for a flying cart that was basically a quad like in design and a few human powered helicopters but not much else. You hit the reason on the head when you pointed out the safety problem. All engines fail while in flight at some point which is why aircraft don't get very far in manned aircraft design.
Speed of deployment and the ability to be deployed while the cars is moving are the really the only other small advantages. So too me this idea seems best suited for on the move front line duty where you don't want to be bothered with batteries. But if you ask me I’d take a tether less UAV over this any day myself.
Just remember to winch it in before you go under the power lines...
Someone asked me a while ago, why don't we have quad's big enough to put people into? The only thing I could think of is that they take a lot of space and they don't crash nicely like planes and (regular) helicopters. Anybody have any other good reasons?
The manned quad was built and flown in the 50's if you can believe it. What can be done with today's technology and simple controllers?
