Virgin Galactic announces milestones in next SpaceShipTwo manufacture

 

 

Virgin Galactic (Mojave, Calif., U.S.) has announced two manufacturing milestones for its next SpaceShipTwo spaceship, which is planned to enter service after VSS Unity: the fuselage and cabin have been mated to the completed wing assembly, and the two tail booms have been mated to the spaceship’s rear feather flap assembly. 

With these milestones, the part fabrication of the wing, fuselage, cabin, nose and feather flap primary structures is now complete for the second commercial spaceship, the company says. In addition, the majority of systems integration for the wing is complete, as well as the build of the cabin crew station installation.

SpaceShipTwo vehicles are assembled in a modular fashion, with the cabin, fuselage, wing and feather assemblies built in parallel. Employing Design For Manufacturability and Assembly (DFMA) techniques, this approach is said to grant easier access for systems integration earlier in the build process, as well as an overall shorter assembly duration.

 

 

Virgin Galactic established operations in Mojave, through its development and manufacturing arm, The Spaceship Co., to build and assemble a fleet of spaceships and carrier aircraft for the Virgin Galactic operations in New Mexico. While VSS Unity continues to progress through its comprehensive ground and flight testing program, the Mojave-based team has been diligently building two additional SpaceShipTwos.

“Our passionate and talented team has made great progress on the next SpaceShipTwo,” says Enrico Palermo, president of The Spaceship Co. “Our passionate and talented team has made great progress on the next SpaceShipTwo. Seeing VSS Unity adjacent to the assembly of the next vehicle as well as the cabin of our third spaceship makes it very clear that we are building a fleet of remarkable spaceplanes for commercial service.”

Before mating the two assemblies, the metrology team used laser trackers to capture precise measurements of the fuselage and cabin and the wing. These measurements confirmed that the assemblies would come together as they were designed to, the company says.

In parallel to this operation, the feather assembly is taking shape. The inboard skins have been bonded to the boom internal structures and then rotated vertical and mounted on the feather flap assembly. The feather flap assembly is responsible for moving the spaceship’s booms into the feathered position used for stable re-entry through Earth’s atmosphere.

“It is exciting to imagine these two vehicles operating shoulder-to-shoulder from Spaceport America in New Mexico,” says George Whitesides, CEO of Virgin Galactic and The Spaceship Co. “We have a strong block design which we believe we can replicate to build the remainder of the fleet, continuing our march toward commercial service.”
