This thesis investigates the configurations needed to demonstrate positive lateraldirectional controllability across the flight envelope of a hypersonic vehicle. Itexamines the NASA Space Shuttle Orbiter as a baseline reference configuration, as it
was a successful hypersonic vehicle. However, the Orbiter had limited high-speed
maneuvering capability; it relied on reaction-control jets to augment controllability
due to a strong tendency for its aerodynamics to “control couple.” It was seen that
many problems associated with the control of the hypersonic Orbiter are due to its
slender configuration. This work relies upon the Evolved-Bihrle-Weissman chart as
an accurate indicator of lateral-directional stability and controllability. The also
explores variant configurations of larger wing tip verticals to explore what
configuration changes are needed to reduce dependence on reaction controls.
