A rocket-powered spacecraft having a wing which has hinged aft portions
which can be elevated about a hinge line. Tail booms extend rearwardly
from the outer ends of the aft wing portions, and rudders are mounted at
the aft ends of the booms. Each tail boom supports a horizontal tail with
an elevon at its trailing edge. In normal flight, the wing aft portions
are not elevated, and the wing has a normal airfoil shape. During
atmosphere reentry, the wing aft portions are steeply elevated to provide
a stable high-drag altitude for the spaceship for speed reduction at low
thermal and structural loading. After reentry, the aft wing is returned
to an unelevated position which enables gliding flight to a
horizontal-runway landing.
