The Rutan SpaceShipOne Revealed 404
smartalix writes "Burt Rutan's company, Scaled Composites, announced that they have been developing a commercial manned space program in secret for the past two years. The system consists of a carrier vehicle called the White Knight and a piggyback (actually underslung) orbital spaceplane called SpaceShipOne. My money is on this effort capturing the X Prize." Well, it's pretty, whatever it is. Space.com has a story with pictures for those of you who weren't quick enough to hit scaled.com before it melted.

Re:Rutan history (Score:4, Insightful)
In a conventional layout, the horizontal tail generates lift in the downward direction, to balance the center of gravity, which for stability reasons is located ahead of the lift vector of the main wing. Therefore, the main wing must generate enough lift to carry the aircraft, and enough lift to offset the downward force from the tail. This extra lift also creates extra induced drag. (Any time you create lift, you also create drag. No getting around it.)
Since the canard locates lifting surfaces at either end of the airplane, with the CG in the middle, both surfaces can generate lift in the upward direction. Less lift overall is required.
Properly designed canard aircraft are also extremely resistant to stalling. Since the canard is typically shorter in chord than the main wing, it will stall first and bring the nose of the airplane down.
Rutan has built two aircraft that have been resounding public successes (the Vari-EX homebuilt and its derivatives and the Voyager), and numerous military prototypes. Just for fun, he designed his personal aircraft (the Boomerang) to be completely asymmetrical.
The thing that I love about aero. engineering is that aircraft that are properly designed also, by virtue of the laws of nature that drive their shape, have an aesthetic sensibility to them. So, in that sense, it IS about the thing being pretty. Obviously, there's more to it than that, but there is a fundamental aesthetic to good aerodynamic design.
Rutan also has a history of extreme lateral thinking when solving aerodynamic problems. Unlike most designers, he throws the history book out the window when he builds a new airplane, and he often comes up with insightful and clever new layouts in the process.
The Pond Racer was another favorite of mine, but its engines were problematic. Unfortunately, it crashed in 1993, killing its pilot. Air racing is dangerous.
How about borrowing from German ideas? (Score:5, Informative)
Late in World War II, the Junkers company built a number of specially-modified Ju 88 bombers that had a large explosive warhead fitted in place of the four-man cockpit. Junkers fitted special brace mounts on top of this modified Ju 88 so accommodated a small fighter like an Me 109G or Fw 190A series fighter airplane. The whole composite flying unit (called Mistel) was guided by the pilot in the fighter until near the final dive into the target, where the fighter separated from the Ju 88 to escape while the bomber flew straight into the target. Mistel was used late in World War II, though its success was marginal at best.
Very late in World War II, engineers at Daimler-Benz took the idea of Mistel to the next level with their A composite flying machine project proposal. It was essentially a large jet-powered airplane with relatively tall fixed undercarriage that had a smaller jet powered bomber slung underneath. This allowed the smaller bomber to fly much further than possible, since the smaller bomber didn't need to consume fuel on the way to the target.
Essentially, the Rutan SpaceShipOne unveiled today uses the same technological ideas pioneered on the Daimler-Benz A project, but with modern aerospace materials and engines the whole composite flying unit is vastly lighter than the German project.
Just FYI. =)

The FAQ
Frequently Asked Questions
VISION
What does Burt Rutan think of the other X-Prize designs?
Burt prefers to discuss this only after the X-Prize is won.
How long has Burt been working on all this?
The concept dates back to April 1996. Design work and some limited testing was started 3.5 years ago. The full development program began in May 2001.
What's going to be next in Burt's bag of tricks?
Scaled has completed 34 manned research aircraft and none were announced until they were ready to fly.
BUSINESS
How much does it all cost?
This is generally not known until the program is complete, but projections place it close to a Soyuz ride.
How much will it cost to get a ride into space?
Rides will not be offered in SpaceShipOne. The price of a ride will have to take in consideration the cost of certification and establishing an airliner-like operation. One goal of this research program is to see how low it might be without the burden of regulatory costs. At program completion we will have good data for operational costs and may publish them.
Is it physically stressful?
It is expected to be on the order of some modern theme park rides. The highest forces occur during reentry but build up gradually and peak near 6 G's for less than 10 seconds. With the pilot and passengers reclined, these forces should be quite tolerable for anyone in reasonable health.
Is Burt Rutan going to ride in the vehicle?
Yes, as soon as the opportunity presents itself.
WHITE KNIGHT
Why did the first flight last only 2 minutes?
The airplane had outboard spoilers on the wings to help improve roll control in the event of gusty cross wind landings. They were pneumatically actuated (using the same tanks, valves and fittings as the RCS system on SpaceShipOne) and returned to recesses in the wings by springs. On the first flight, the low air pressure, at rotation was sufficient to "suck" the spoilers out which killed the lift and caused the return springs to slam them closed. Four of these surfaces chattering out on the wingtips during the climb out produced significant airframe vibrations and the pilot elected to turn downwind and land immediately rather than aggravate the condition any longer than necessary.
How can you see where you're going?
The visibility is actually much better than you might imagine. By moving your head slightly you can piece together an acceptable picture of the outside world and maintain adequate "situational awareness". What is more difficult is spotting other airborne traffic. However, between radar advisories from ground controllers and an onboard traffic alert system called "Skywatch," this limitation is minimized.
Isn't it hard to land with all those wheels?

he can hold them off until about 45 knots during the landing roll.

Why is the cockpit called a "pressure vessel"?
The cockpit is airtight and the air is not freely exchanged with the outside air. So like a submarine the structure must be able to withstand large forces due to the pressure differential. In the case of this vehicle, there is high pressure air inside compared to the near vacuum outside.
How do you keep the air breathable?
There are three components to keeping the cockpit environment suitable for flight. One, oxygen needs to be added at a small rate for that used by breathing. This is done with a small bottle carried in the cabin. Two, the carbon dioxide from the exhaled air needs to be removed and this is done by means of a substance called "Sodasorb". Finally, the humidity is controlled by another substance called "3X"that removes water vapor, keeping the cabin cool and dry.

It is true that you won't be orbitting at 1mph. However, if you consider the the velocity vector that is perpendicular to the Earth's surface, it is most certainly possible to reach orbit with a vertical velocity of only 1mph. Not fuel-efficient, of course.

Escape Velocity is what's required to escape the earth's gravity.
Reaching Earth Orbit is NOT escaping earth's gravity.

When it's a couple inches from my back, I don't really distinguish between exploding and burning really fast.

And in typical Rutan fashion, it'll probably work perfectly the first flight, and cost less than 1/10th what NASA could do it for
Interesting story:
I attended a lecture Burt gave last year (at Oshkosh Airventure 2002) and he was talking about the Proteus. They were involved in an air quality experiment. There were several layers of airplanes in a vertical stack -- the Proteus was assigned the 65,000ft layer, and a NASA U2 was given the 68,000ft assignment. The U2 (which was only flying 3000ft above the Proteus) had a full maintenance crew of 40. The Proteus came with a crew of 2! Rutan stated that they spent most of their day on the ground, playing cards and waiting for the U2 crew to finish maintenance....

As I recall when the U2 was on the boards, they had to practially reinvent the wheel just to keep it from bursting at their mission altitude.
Rutan simply capitalized on the work that Lockheed's Skunk Works team did and took it a step higher and further, with fewer nuts to take care of the bird..
Of course, you gotta remember, the U2 IS a government aircraft so there is some beraucracy behind it..
If it was stil
