WhiteKnightTwo ready

Virgin Galactic Breaks Own Altitude Record

Now that 2014 is finally here, Virgin Galactic‘s first commercial flight with its WhiteKnightTwo / SpaceShipTwo combo edges ever so closer to reality with every day that goes past. A few days ago, they launched SpaceShipTwo 71,000ft up in the sky and tested several critical features in the process, as Virgin Galactic’s Chief Pilot Dave Mackay was at the helm. One of the features being tested were the newly designed thrusters (RCS) which are used by the pilots to maneuver the vehicle in space. The other feature on trial was the tail section’s new coating which reflects heat produced by that massive rocket engine sitting just behind the passenger’s cabin as it were. SS2’s unique feather re-entry system was also tested during today’s flight.

As the company was gathering a ton of transonic and supersonic data, Sir Richard Branson said the following of the successful flight (the third supersonic, rocket-powered test flight of Virgin Galactic): “I couldn’t be happier to start the New Year with all the pieces visibly in place for the start of full space flights. 2014 will be the year when we will finally put our beautiful spaceship in her natural environment of space. Today, we had our own Chief Pilot flying another flawless supersonic flight and proving the various systems required to take us safely to space, as well as providing the very best experience while we’re up there.”

Scaled Composites WhiteKnightTwo

WhiteKnightTwo

The launch vehicle that Virgin Galactic will be using as part of its two-stage approach to sub-orbital spaceflight is the WhiteKnightTwo (also known as WK2), with the first one christened VMS Eve after Richard Branson‘s mother and the second one will be named after Steve Fossett, that other adventurer who sadly had a less than fortunate encounter with fate in 2007.

Developed by Scaled Composites under the umbrella of The Spaceship Company, the first WhiteKnightTwo was revealed to the public for the first time in July 2008 and the prototype has since made over 100 test flights. As a design, it is hard to miss. WhiteKnightTwo features a unique twin fuselage ‘catamaran’ design with an unswept single piece wing. This catamaran airframe configuration allows for flexible payload placement and configuration.

For the full technical specifications, you can download the pdf here. It is a true aviation milestone: the largest all carbon composite aviation vehicle ever built with an amazing 140 ft wing span, capable of carrying heavy payloads (up to around 16 tons) to high altitudes (around 50,000 ft, or over 15 km). Putting that in perspective, that payload is about equal to what an Arianne 5 rocket can launch into geostationary transfer orbit (GTO).
