PICTURE: Virgin Galactic makes WhiteKnight Two structural changes
By Rob Coppinger

To solve handling and stability problems Virgin Galactic has made structural modifications to the vertical stabiliser fins of its WhiteKnight Two carrier aircraft prototype Virgin MotherShip (VMS) Eve.

Flightglobal.com has obtained photographic evidence that VMS Eve's two booms' vertical stabilisers have been reshaped by prime contractor Scaled Composites for a larger lower rudder hinge and a more pronounced horn that may contain a heavier counterweight. The image also shows two new vortex generators added just forward of the lower hinge point and the right boom's fin has a new antenna bulb attached to its top.

The two pictures in the composite image below were taken before and after the second test flight that took place on 5 February. The left hand side of the composite image was taken before that second flight and it is the port boom.

The right hand side of the composite image shows the starboard boom since the second test, now altered in preparation for the 25 March third flight. Before the 25 March test the left boom fin was altered in the same way as the right hand stabiliser.

The spaceline's president Will Whitehorn had described the 5 February second flight as "flawless".

The structural modifications to the fins would explain the seven week gap between the second and third flights. Virgin Galactic declines to comment on any aspect of the test flight programme in detail including technical matters regarding the flight test prototype VMS Eve.

Flight first reported a possible rudder issue for VMS Eve on 7 January this year and published a photo on 6 February showing the prototype with vortex generators added to the vertical stabilisers.

Official Virgin Galactic video of flight testing, released on 27 March, can be found here while earlier test footage including taxi runs obtained by Hyperbola can be seen in this blog post.

Images of the spaceline's air and spacecraft can be found here at airspace.aero's Virgin Galactic gallery.

Space Vehicle Profile: WhiteKnightTwo

With its successful maiden flight on 21 December 2008 Scaled Composites WhiteKnightTwo mothership is expected to start carrier flight tests with its SpaceShipTwo (SS2) payload later in 2009.

The WK2 design, an all-composite airframe with a 42.7m wingspan, booms that give it a length of 23.7m and a tail height of 7.62m, was unveiled in January 2008. The experimental WK2 prototype was rolled out at Scaled Composites’ Mojave air and spaceport facility on 28 July.

Using four Pratt & Whitney Canada PW308A engines WK2 has a payload capacity of 17,000kg (37,400lb) to 50,000ft, a range of 4,200km (2,270nm) with SS2 attached, and will be capable of a Viking departure without it.

WhiteKnightTwo’s four engines are to ensure a take-off capability while carrying SS2 even with an engine out.

The WK2 mothership uses the same cabin design as SS2, allowing for pilots and space tourists to prepare for flights in the spaceship. The mothership’s two pilots will operate the aircraft from the right fuselage's cabin, looking at WK2 from a plan view, while passengers could one-day travel in the left fuselage to watch SS2 launches.

Designed for spaceline Virgin Galactic’s proposed suborbital service that is to begin in 2010 from New Mexico’s Spaceport America, it will take-off from a normal runway and carry the SS2 to around 50,000ft, release it and then return to the spaceport.
