back to article SpaceShipOne firm to build DARPA's Heliplane

The US military's ongoing bid to revive grand old vertical lift concepts of the 1950s under the name "Heliplane" has gained a new lease of life. The financially-distressed main contractor is to be replaced by researchers at the Georgia Institute of Technology (GIT), and the airframe will now be made by renowned high-tech company …

I was sure I'd seen the rear end of the thing before somewhere -- just looked on the bookshelf and there is it -- on the back of Thunderbird 2.

"The involvement of Scaled would seem to promise at least one surefire benefit: The relatively dull biz-jet based concept art for the Heliplane (as shown above) should soon be replaced by something a bit snazzier. ®"

Carter Copter

Attended a conference at Sun-n-Fun last year. Reviewed the concepts involved for the jump-takeoff carter-copter. http://www.cartercopters.com/

This technology actually works! The are able to tip the mast forward, and slow the blades to reduce drag for high-speed flight. That, and they can control the pitch of the blades for jump takeoffs and near-vertical landings.

GIT - a propitious name

They might have sent the thing to Texas' Sam Houston Institute of Technology.

But what is the deeper meaning of America's move to failed technology from Blighty? As I recall, this design was from the start of Britain's decline as a world-beating engineering power- does this mean that America is entering a similar death-spiral?

Not a new idea

Lockheed did it back in the Sixties with the AH-56; Piasecki is doing it now with the X-49, and Sikorsky with the X2. "compound helicopters" have been a good idea for a long time.

The problem is that the USAF got all butthurt about them; "they're aircraft!", cried the blue-suiters, but since they're expected to do helo duties the USAF didn't actually WANT to operate them. (Similar to UAVs now.)

As A US Engineer... yup.

Thumb Up

one small detail incorrect

this concept, which is pretty much the aforementioned Cartercopter concept in military form, does *not* have tip jets. The rotor is prespun by driveshaft. After it's up to operating RPM it's up to the patented braking magic to get the rotor travelling at lower speeds, as well as tricks to avoid nasty blade oscillation. This is a "simple" concept, that hasn't worked in the past because of a whole lot of "little" details that the Carter crew have found some rather elegant solutions for.

The Sikorsky single-rotor craft failed because they could not address blade oscillation problems. Dual rotor craft are much more complex with all sorts of nasty control linkages that fail easily. This might actually be the first shot at making this type of aircraft efficient, reliable and safe.

hell, Carter is talking about making a turbodiesel powered model. That's right, biofuel time. So now it's cool, quieter and *green*

Mine's the one that smells like onion rings and french fries.
