This presentation looks at new technology being used which is enabling commercial technology. the feathering design of the wings by Burt Rutan significantly reduces the risk associated with re-entry into the earth’s atmosphere.
The spaceships design ensures it will make what Rutan calls a "care free" re-entry, much like a badminton shuttlecock. With its rear wings steeply tilted, the spacecraft will experience enormous aerodynamic drag, minimizing re-entry temperatures and stresses, which will force the craft to assume a cabin-level orientation that does not require a precise angle of attack. In contrast, traditional space crafts must re-enter in a carefully controlled orientation with a steep nose-up angle of attack to keep temperatures at or below leading wing edge design limits of about 1650 degrees Celsius. Rutan’s feathering technique ensures maximum temperatures do not exceed 260 degrees Celsius.
