Title: Saucer Car

Description:
Since mini car is getting much smaller and lighter the engine power requirement is lighting up. The price tag to make a flying car will be more affordable and easier. My idea is using the current manipulation of a car, which ordinary people already know how. When is needed, it can fly from driveway, at allocated shoulder space on the road, at lake shore or sea shore, it can sails as a ship. The followings are in consideration:
     1) The car needs a more powerful engine   2) Need lighter structure, the material are most of fiberglass or aluminum   3) The car should be waterproof at bottom, move as inverse umbrella, which has propeller design   4) The car will he saucer shape to have more even woight   5) The car should be fly and sailing straight without rotation to avoid vertigo   6) The Propeller of helicopter need to fold like a bird wing, in order to drive on regular roadway.
       When prepare to fly, it need a larger shoulder space to unfold the propeller.   
       7) The main requirements in additional to current cars are:
       a) Vertical, top and bottom, 2 propellers   b) Car differential need be convertible, Lock and Unlock, for car and vertical fly situation   c) Additional front and back propellers   d) Additional transmission stick to control front and back propeller when helicopter in hover position to move forward. (this can adopt current helicopter measure too)   e) The Propeller movement need opposite each other direction controlled at the differential box   f) Vertical Fins attach to main wheels for direction control when driving wheel is handled   g) Drop down pad when braking while in flying or sailing
 
As the above idea, the following designs and drawings is requiring your honor to judge the feasibility.

     SPECIFICATION 
     The following utility design is to modify the structure and control mechanic of the current car with the combo functions: Drive on land; Fly in air; Sail in water.
         1) Drive on land: same as current car in structure and handling
           But in order to drive in current roadway, the long propellers are foldable by a joint,   which is operated by a small motor similar to the closing device of a car window as show in  FIG. 1 .   
           2) Fly in air: The “ DIFFERENTIAL”, in the car for wheel diving, will covert power to vertical upper and lower propellers driving as in  FIG. 3 . Both propellers move in opposite directions at “ DIFFERENTIAL.” box. The lower propeller designed as an inverse umbrella in order for water sailing purpose. Forward moving is depended on 2 propellers mounted in the front and rear. Those move in opposite manner.   3) Sail in water: The reverse umbrella acting as floating cup, the vertical axle is a sealed cylinder at both ends as  FIG. 3 . The forward movement is depend on 2 propellers mounted in the front and rear as  FIG. 4 . The vertical 2 propellers also add the floating power of the car.       

    
    
     Explanation of Drawing 
       FIG. 1 : is the bird eye view of the saucer car (big circle), folding joint, (small circle). The joint is sandwich or biscuit like structure, in order to enforce the strength of propellers. The folding or unfolding is controlled by window motor in current car. 
     Fig. 2 : is the bird eye view of the saucer car (big circle),  4  wheels (sausage shape), front and back  2  wheels are passive wheels. 
       FIG. 3 : demonstrates the differential box to convert the land driving to helicopter driving. The box in the center has locking and unlocking gears wheels, which is controlled by differential stick as shown in  FIG. 6 . The differential at center bottom is fixed, it is similar to ordinary front wheel drive. The half circle represents the reverse umbrella propeller. 
       FIG. 4 : is the side view of saucer car 
       FIG. 5 : is the posterior view of the saucer car 
       FIG. 6 : is the regular car handling stick, driving wheel, brake, gas pedal, plus add on differential stick for functional change of air, land and sea and another stick for moving forward . 
     FIG. 7 : is to demonstrate current car gear box modification for front and rear propeller control and helicopter differential box
