ABSTRACT:
A vehicle for traveling in the air and/or on the ground is equipped with two, four, or eight propellers on vertical shafts, each driven by a rotary hydraulic motor of the radial-piston type. The motor may comprise two rotors which are connected in individual hydraulic circuits supplied with fluid from different hydraulic pumps. One embodiment of the vehicle comprises an automobile with the propellers mounted in oblique air ducts or in shrouds pivotable in the travel direction. Each rotor of the hydraulic motors is coupled to the shaft unidirectionally so that in case of failure, the shaft can be driven by the other rotor. Each hydraulic pump preferably produces four equal fluid flows and comprises two rotors on a common shaft, each rotor with two separate groups of cylinders, the eccentricity of at least one of the rotors being adjustable. Both the hydraulic motor and the pump have inlet and outlet connections on the radial periphery of the housing. The pumps and the engine are mounted on a lowerable and retractable substructure which may lowered below the body of the vehicle at flight in air and be retracted into the body of the vehicle when travelling on the ground.
