Description White Knight SpaceShip One
White Knight

The White Knight is a manned, twin-turbojet research aircraft intended for high-altitude missions. First flight was on August 1, 2002. Design mission - provides a high-altitude airborne launch of SpaceShipOne, a manned sub-orbital spacecraft. The White Knight is equipped to flight-qualify all the spacecraft systems, except rocket propulsion. The White Knight’s cockpit, avionics, ECS, pneumatics, trim servos, data system, and electrical system components are identical to those installed on SpaceShipOne. The White Knight’s high thrust-to-weight ratio and enormous speed brakes allow the astronauts in training to practice space flight maneuvers such as boost, approach, and landing with a very realistic environment. Thus, the aircraft serves as a high-fidelity moving-base simulator for SpaceShipOne pilot training.

Other White Knight mission capabilities include: reconnaissance, surveillance, atmospheric research, data relay, telecommunications, imaging & booster launch for micro-satellites.

FEATURES/CAPABILITIES:

* Carriage and launch of payloads up to 8,000 lbs
* Internal fuel capacity up to 6,400 lbs
* Altitude capability above 53,000 ft
* Large, three-place cabin (60” diameter outside, 59” inside)
* Sea level cabin qualified for unlimited altitude
* ECS scrubs CO2, removes humidity and defogs windows
* Two crew doors with dual seals and dual-pane windows
* Manual flight controls with three-axis electric trim
* Avionics include INS-GPS navigator, flight-director, flight test data (recording and T/M), air-data, vehicle health monitoring, backup flight instruments, and video system
* Propulsion is two afterburning J-85-GE-5 engines
* The 82 ft wing can be extended to 93 ft for increased climb capability
* Super-effective, pneumatic speed brakes allow steep descent with L/D < 4.5
* Hydraulic wheel brakes and nose-gear steering
* Pneumatic main gear retraction
* Dual-bus electrical power system
* Cockpit allows single-pilot operation (VMC-day conditions only)

SpaceShipOne was developed by Mojave Aerospace Ventures (a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company, in their Tier One program), without government funding. On June 21, 2004, it made the first privately funded human spaceflight. On October 4, it won the $10 million Ansari X PRIZE, by reaching 100 kilometers in altitude twice in a two-week period with the equivalent of three people on board and with no more than ten percent of the non-fuel weight of the spacecraft replaced between flights. Development costs were estimated to be $25 million, funded completely by Paul Allen.

During its test programme, SpaceShipOne set a number of important "firsts", including first privately funded aircraft to exceed Mach 2 and Mach 3, first privately funded manned spacecraft to exceed 100km altitude, and first privately funded reusable manned spacecraft.

SpaceShipOne is an experimental air-launched rocket-powered aircraft with suborbital flight capability that uses a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folded upward along a hinge running the length of the wing; this increased drag while remaining stable. The achievements of SpaceShipOne are more comparable to the X-15 than orbiting spacecraft like the Space Shuttle. Accelerating a spacecraft to orbital speed requires more than 60 times as much energy as accelerating it to Mach 3.

The only thing this is missing is the ability to attain and return from orbit. That ought to be another 10 years from now. Here's hoping.

Um, I would hazard to disagree with you. A lot of the actual work on re-entry shaped bodies has already been done by NACA/NASA back in the 60's and 70's.

It will just take the right amount of application/experimentation to join the research with the hard ware.

Much cheers!

You aren't wrong there. The "feather" design makes it better for re-entry as a more controlled fall. What I'm thinking of is having enough thrust to actually get to orbit and still have enough fuel or propellant to get back down. So Far as I know Spaceship one can not actually make a sustained orbit. It just glides on the outer edge of the atmosphere for a bit before coming back down.

Ah, well adding fuel and dropping passenger space would allow for a higher flight, possibly even putting it into low The problem is S-1 has no heat shielding against re-entry/deceleration. Hence the sub orbital stuff. Adding shielding/changing the shape makes for a whole new craft. I'm sure folks are working on something like a fully orbital craft, though.

Much cheers!

Hence my original comment that it may take 10 years.

*snerk Sorry, yah well we'll see where people spend their money.

The thing I still find interesting is from reading Chuck Yeager's autobiography. In there he says that the early NASA folks basically realized that a suitably 'stretched' and tweaked X-15 would effectively make it easily into the sub orbital range and be useful for doing a lot of the 'early' research stuff for stepping beyond into full orbital. (Plus Yeager knew about the ballistic lifting body experiments, having test flown one of the experimental vehicles himself.) The big wigs canned and poo-pooed the idea since they couldn't see the 'practical applications' of such....

Of course a year or so after, Yuri Gagarin cam along and then, suddenly, every one from the top down seemed to go into panic mode.

I found reading Mr Yeager's book entertaining, interesting and insightful. Of course they are still just the thoughts and experiances of one man, but what a life that one man has be fortunate enoug to lead?

Young-ish reporter interviewing Elder statesman:
"Mr Yeager, what did you do the first time you saw a jet aircraft"

Chuck Yeager's reply:
"I shot the damn thing down."



Cheers!
