A propeller mounted toward the front of the vehicle provides both propulsion and air cushion. A body section has lateral openings on each side of the vehicle behind the propeller. Front steering and thrust spoiling are obtained by sets of vanes rotatably mounted in these openings and spaced progressively rearwardly and inwardly in diagonal disposition. In turning, predetermined vanes of one set are turned outward and those of the other set inward. For thrust spoiling, both sets are preferably turned inward. Air flow to rear steering vanes on the outside of a turn is maintained for at least smaller turning angles by initially turning the forward vanes of a diagonal set faster than the rearward vanes of the set, or by using fixed air channels, or both. It is presently preferred to use fixed air channels controlled by respective rearward vanes of the diagonal sets to maintain air flow to the rear steering vanes on the outside of a turn for a major portion or all of the steering range, while reducing air flow to the rear steering vanes on the inside of the turn for at least larger turning ranges within the steering range. Transversely-disposed sets of vanes mounted between the diagonally-disposed sets are controlled to direct air toward the outside of a turn progressively as the turning angle increases. Differential control of air flow to the rear steering vanes is also described.
