A jet engine 14 is located at the rear of the vehicle. An operator/passenger compartment 16 including a canopy windshield 18 provides access to and from the compartment 16 at the front of the vehicle 2. The canopy windshield 18 has a removable portion to provide a convertible mode for both the road and aircraft forms of the vehicle 2. In the convertible mode, front and rear windshields remain in place, while a middle overhead or roof portion is removed. The canopy windshield 18 is also hinged to the vehicle body at hinge 20 at the rear of the compartment 16 to allow the canopy windshield 18 to be opened and closed as a unit which includes the front and rear windshields and the middle roof portion. The compartment 16 is accessible by retractable steps 22 that fold out from the compartment 16 at the front of the vehicle 2. A hood 24 of the vehicle is formed when the steps are in a folded in, retracted position. Headlights 21 are provided on the sides of the hood 24. Alternatively, access to the compartment 16 may be made by entering through access windows (not numbered) provided on the driver and passenger sides of the vehicle 2.
[0019] Rearward of a body panel 26 at the rear of the driver's compartment 16 is a propelling assembly 34 for driving the vehicle 2 in its aircraft form. The propelling assembly 34 is mounted on the body panel 26 and includes the rear engine 14 and a tail assembly 40 for use of the vehicle 2 in its aircraft and water form.
[0020] Rearwardly of the propeller assembly 34 is the tail assembly 40 for use of the vehicle 2 in its aircraft and water form. The tail assembly 40 has a pair of side vertical stabilizers 42 connected together at the rear thereof by a horizontal stabilizer 44. Stabilizer 44 doubles as an elevator and the vertical stabilizers have conventional rudders 48. The tail assembly 40 also includes a pair of horizontal rudders 50 attached to the vehicle body extending over and behind the rear wheels 12. All of the rudders and the elevator are controlled by the operator from the compartment 16 by suitable means.
[0021] The rear jet engine 14 of the tail assembly 40 is rotatable by 90 degrees about a horizontal axis relative to the vehicle body, at pivot element 52, which is shown as a pancake type gear motor. The engine 14 is pivo tally supported by the vertical stabilizers 42 and left and right side pivot elements 52 of the tail assembly. A mechanism (not shown in detail) is provided which rotates the engine 14 from a horizontal propelling position to a vertical propelling position. Furthermore, the rear jet engine 14 is rotatable about a vertical axis relative to the vehicle body, at pivot point element 54, also shown as a pancake type gear motor, so as to be positioned at varying angles within a horizontal plane. A mechanism (not shown in detail) is provided which rotates the engine 14 about pivot element 54.
[0022] The vehicle employs wings 60 capable of being folded to lie along the vehicle in the road form and capable of being extended out laterally in the aircraft form.
[0023] The wings 60 are each pivotally connected to a wing journal 64 by a hinge 68 and secured in an extended position by lock pin 66. The wing journals 64 are rotatable mounted to the sides of the vehicle body adjacent to the compartment 16. A mechanism
80 is provided on both sides of the compartment 16 for rotating the wing journal 64 of each wing 60. The wings are supported with extension arms 62 made of telescoping tube actuators which are attached at one end to the underside of each wing and at the other end to the respective wing journal 64. Extension arms 62 serve as reinforcing and anchoring struts for the wings 60 in the extended flying position of the wing 60 and in the retracted road position. Each wing 60 is provided with a jet engine 90. The wings 60 are retracted and extended by means of the telescoping tube actuators or hydraulic cylinders of the extension arms 62 and are rotated by means of the rotating mechanisms 80 for the wing journals 64. The wing journals 64 can be made for example with a rolled channel with cam rollers to bear the thrust load and wheels rolling in a channel web for example to bear the radial load. A standard type ball bearing could be used. Suitable control systems and mechanisms for automatic rotation and actuation of the wing assemblies are provided.
[0023.2] With particular reference to the drawings, FIGs. 7 and 8 show the vehicle 2 according to a second embodiment of the invention. FIG. 7 shows the vehicle 2 in its road and water ready form and FIG. 8 shows the vehicle 2 converted to its aircraft or flying form. The second embodiment will be described and shown with like elements numbered the same as the first embodiment. The first and second embodiments of the convertible vehicle are substantially the same, except for the propulsion system which will be described hereinafter. Description of the like elements will thus be omitted.
[0023.3] In the second embodiment, shown in FIGs. 7 and 8, each wing 60 is provided with two ducted fans or in-wing propellers 90a which are fixed in their position relative to the wings 60. Rotation and positioning of the wings 60 in the second embodiment is the same as in the first embodiment and the description thereof will thus be omitted. [0023.4] Rearwardly of rear windshield 18a and body panel 26 at the rear of the driver's compartment 16 is a propelling assembly 34a for driving the vehicle 2 in its aircraft form. The propelling assembly 34a includes a rear propeller 14a and tail assembly 40a for use of the vehicle in its aircraft and water form.
[0023.6] Rearwardly of the propeller assembly 34a is the tail assembly 40a for use of the vehicle in its aircraft and water form. The tail assembly 40a has a rudder 48a attached to the propeller 14a. The rudder 48a allows the vehicle to be rotated about a vertical axis while in its aircraft and water form. The tail assembly 40a also includes a horizontal rudder/stabilizer 50a attached to the vehicle body behind the rear wheels 12. All of the rudders are controlled by the operator from the compartment 1 by suitable means.
[0023.8] The rear propeller 14a is moveable about a horizontal pivot element 52a, between a horizontal position shown in FIG. 7 and a vertical position shown in FIG. 8. A mechanism 56 is provided which rotates the propeller 14a about the pivot element 52a. The mechanism 56 has two actuators 57 linked to the vehicle body at one end and to a frame 58 which supports the propeller 14a and the other end. The actuators 57 enable the propeller 14a to be positioned between a flat or upright position, depending on the operating mode of the vehicle.
[0024] In both embodiments of the invention, the body of the vehicle 2 and the wings
60 are aerodynamically shaped to provide vertical lift when flying. The wings 60 can be rotated 360° to provide lift and to advance the flying position. Additionally, by rotation of the wing assemblies in mid air, the vehicle can hover in a stationary position. The rear engine 14 or rear propeller 14a of the vehicle rotates from a vertical to a horizontal position for take off and landing and flying vertical take off or landing (VTOL) teclinology is used for both takeoff and landing. When used as a car, the wings 60 are rotated and folded to lay flat against the sides of the car so that the site line is not blocked. To summarize, the rear thrusters can be propellers, jets or prop jets. In the propeller version of the flying car, there are two propellers 90a on each wing and the propellers are mounted within the body of the wing 60. In the jet version of the car, one jet 90 is mounted to each wing. A control system, i.e. a computer, could be used in automatic or manual mode for takeoff, landing and flying. The car is designed to float so that it can also be propelled in water by the rear engine 14 or rear propeller 14a, and steered by rudders 48a, 50, 50a. It is noted that a runway is not needed to take off and land the car. When used as a car, the propellers and jets are not used. Instead, the wheels of the car are driven by high efficiency hydraulic, air, or electric motors. It will be understood that all entrances, wheel wells, wing journals, windshields, etc. will be sealed so as to be watertight for use of the vehicle in its water form.
[0025] According to the present invention, a combined road, water, and aircraft vehicle is provided which is readily convertible from one form to the other. Such conversion is accomplished by a single person if necessary and without special tools and in a reasonably time. All the parts of the vehicle are intact and merely pivot or rotate into place during conversion.
[0025.2] The operating modes of the convertible vehicle will be described hereinafter.
The road and water ready mode of the vehicle are shown in FIGs. 3 and 7. In the first embodiment, the jet engine 14 is in a horizontal position, and in the second embodiment the propeller 14a is in a flat or down position. The wings 60 are folded back and rotated with the jets 90 facing downward in the first embodiment. The takeoff mode of the vehicle is shown in FIGs. 6 and 8.
