Boeing’s next big VTOL surprise

Forget the VTOL patent I posted on this blog last week. That’s old news.

Walking amidst the exhibits at the Association of the US Army convention, I found out about a completely different kind of aircraft that may finally solve one of the most challenging aerodynamic puzzles: how to design an aircraft that can fly both vertically and horizontally without compromising efficiency in either regime.

Boeing has a contract with the Defense Advanced Research Projects Agency to study design concepts for a new breed of hybrid vertical takeoff and landing (VTOL) aircraft. It’s called the Disk Rotor, and it looks a lot like this:

I picked these photos off this Swiss web site, but I am reliably informed is very similar to Boeing’s concept.

The aircraft achieves vertical lift and hover with rotor blades that fold out from the rotor hub and retract during forward flight. A pair of engines provide the power for forward flight, during which the larger rotor hub functions as a wing.

    …I’ll believe it when I see a copy fly in reality. Until then, not so fast.

    Wise skepticism. But the point is that Boeing is chasing this, whether the aerodynamics add up or no.

    DARPA, BOEING and Virginia Tech please stop infringing / plagiarizing our disk technology
    Dr. Haynes, DEHAS In and the world first Space airline “ Blue Ridge Nebula Spaceline” (www.blueridgeairlines.com) prepare to demonstrate the advanced flight capabilities of the Haynes Saucer-7 and -8 craft, either in Colorado or New Mexico, next month. we
    The company ask DARPA, BOEING and Virginia Tech to stop infringing / plagiarizing our technology via the he DARPA BAA 08-31 rotating retracting winged disk solicitation managed by Michael D. That’s why we have a Black History month celebration and acknowledgement periods yearly, to keep others from stilling our accomplishment in front of God and you. Dr. Haynes was the first to successfully build and fly our patted aerodynamic rotating gyro disk on NBC television with retractable wings capability way back in 2003 in relation to the FAA/AST and X-Prize space race competition which we ran second in at the time.
    As always you welcome to come along on our historic adventure in aerospace science
    God Bless You all.
