In a vehicle or device a fluid motor is employed to drive rotary members, such as wheels, propellers, tracks. The motor is provided with an arrangement which includes a control means and an axially moveable member. By utilizing the control means, for example, by a flow of fluid, the axially moveable member is used to apply an action, which is not common to the usual operation of fluid motors. The arrangement may be used to arrest the rotor of the motor from rotation when no pressure is in the driving fluid line. It may also be used to control the pitch of propellers with variable pitch arrangements. Also possible is to use the arrangement to automatically obtain an auto-rotation of rotor blades on vertical axes of vertically take off and landing vehicles, when the pressure in the fluid line to the motors for driving the motors drops below a predetermined minimum of pressure. The speciality of the preferred embodiment which is shown in FIGS. 18, 19, 24 to 26 and 34 to 37 consists in the provision of a tail propeller, a main lift propeller and a rate of power varying means in the transmission between the power plant and the mentioned propellers. Thereby the tail propeller acts as forward driving propeller, while the main lift propeller may act with vertical or slightly inclined axis or it may be stopped to rest. The vehicle can thereby fly as a helicpoter or selectively as a gyrocopter and as an aircraft flying on wings if the wing assembly is assembled to the vehicle.

A vehicle capable of travel in air, comprising, in combination, a body, at least one main propeller for the provision of vertical lift, at least one tail propeller for the provision of a forwardly directed thrust, a power plant and a transmission, wherein said transmission includes transfer means for the transfer of power from said power plant to said propellers to drive said propellers at least indirectly for rotary movement, wherein said transfer means include rate of power varying control means for the division of the entirety of the power which is supplied by said power plant into individual variable fractions of said entirety of power with each of said fractions defining a separate rate of power, wherein said at least one tail propeller is directed to drive said vehicle foreward, wherein said rate of power control means subjects said at least one main propeller to said entirety of power for vertical lift and landing, while it subjects said at least one tail propeller to said entirety of power at times of high speed foreward drive when it reduces the rate of power to said at least one main propeller to zero whith said rate of power control means provided with rate of power variation means which are steplessly variable to vary said individual rates of power to said propellers, and thereby the ratio of power between said rates of power, selectively, and; wherein said transmission is a hydrostatic transmission including a variable pump with at leat one variable fluid flow outlet and at least a second fluid flow outlet, fluid lines from said outlets individually to individual flow motors which have rotors which are provided with revolvable shafts which carry said propellers, respectively, while said variable outlet controls by its variability the rotary velocity of one of said propellers relatively to the other of said propellers.
