DARPA DiscRotor might just be UFO that fooled everyone all the while

You can bet your bottom hard-earned dollar that DARPA has a bunch of devices, gizmos and vehicles that we have yet to lay eyes upon as the US strives to maintain their military might worldwide. Recently spotted was the DiscRotor, a vehicle that seems to be a rather strange amalgamation of a helicopter and airplane which can hide its rotors in a spinning disc to get around. Currently in the planning phases (who are we to argue?), why not check out the video in the extended post to see just how the DiscRotor will zip about in real life?

cool hybrid thing

im sure i would also be surprised to see that in the sky

thx for sharing

That's weird because the down draft of the blades pushes on the wings, which you would think cancels out some of the upward thrust. Anywoo....a hybrid is neither a good plane, nor a good helicopter. Plus, it's gotta carry 3 motors....or does the helo-blade get it's drive from the 2 turbines on the wings?

I was thinking it was about to drop a bomb on those people instead of a rope, lol, I guess rescueing people, or one out of three people, is better PR though.

I'm guessing that's an alternative to the horribly accident-prone, and ill-fated mechanical nightmare, the Boeing/Bell V-22 "Osprey"

Maritime armed services (well, the USNavy, and in conjuction, the Marines) strongly desire a viable V/STOL aircraft, with a wide operating envelope in flight, and ability to land/take-off in very close confines.

Here's more, with comments about the program's problems: www.history.navy.mil...

I guess, some of the latest updates seem to show improvements in reliability, and fewer accidents. I haven't read it, but a new book is out about its history.

I suppose its (the "Osprey") worst limitation is speed. 250 knots Max. This new thingie looks faster....

And,not such a good day for those guys...

Common misconception, but a helicopter doesn't produce its lift by forcing air downward, thats just an unwanted byproduct - helicopters produce their lift in the same way as conventional planes do, by moving their lifting surfaces forward through air.

The rotor blades on a helicopter are essentially small wings, the same as on a typical Boeing 747, and they do the same job as those on a typical Boeing 747 - the rotors are turned, which moves the blades through the air, which causes the air to split above and below the blades, causing low pressure about the blades and thus lift.

That lift lesson aside, i find the round shape of the high speed airfoil to be interesting...does it also provide lift or just retracts so the other wings can work better....Whar are the control sufaces in each stage?
Also dos the round part spin when the wings are retracted as well?
Hmmmmm???
