TWO-SECTION RUDDER FOR A VEHICLE WITH HYDRODYNAMIC OR AERODYNAMIC PROPULSION

摘要

An engine for inducing the flow of fluid through a duct is provided ahead of a pair of sets of rudder vanes disposed at the discharge side of the duct which is of V-configuration having the apex of the V turned in the direction of fluid flow. Each set of vanes comprises a plurality of generally flat but aerodynamically shaped vanes swingable about respective vertical axes by independent controls for the vehicle direction so that either set may completely block or only deflect the fluid stream traversing the window of the outlet spanned by the set of vanes.
