Transportation technology has change dramatically in the past century. With the growth of the population, the greater the need is for an improvement in transport. By 2050 the population of the earth is expected to be around 9.6 billion people. Within 1000 years, who knows what the population will be. Driving cars on the road will take too long. There will be an increase of traffic gams with the large amounts of people travelling to work in citied. A solution to this would be to scrap the automobile and introduce the hover car. Multiple lanes of traffic could be located on top of each other.
The hover car design that was made in 123D uses the same principles as airplanes today. Each propeller has a slant on the right-hand side. When the propellers spin anticlockwise, air is forced into the propellers. The air above the propellers is forced to go over the propeller and down the slant at a quicker pace then the air underneath. This elevates the hover car. There are also small versions of aeroplane wings at the front of the hover car. This will also elevate the hover car while it is traveling forwards. At the back of the hover car, there is turbine that follows the same principles as the propellers on this hover car. This is to move the hover car through the air once it is elevated.
Step 1: The Shape of the Hover Car
The basic shape of this hover car was made by drawing a rectangle using the rectangle commanded. Then the circle commanded was used to make the rest of the shape. The centre of the circle was located on the back corners of the rectangle. The complete shape was then extruded to make the basic 3d shape of the hover car.
Step 2: Cylinders
To make the propellers a whole was extruded out of where the rounded parts of the basic shape were. A cylinder was then added to become a support to draw the structures off. The cylinders were then extruded down to the height of the basic shape and then they were extruded down an extra 7mm on both sides of the cylinder.
Step 3: Propellers
At the top of the cylinders and at the bottom, 4 lines were drawn. Each line being drawn from the centre of the cylinder to the end of the basic shape (there is 90 decrease between each line). 4 triangles were drawn by using the original lines as guides. The original lines were then deleted. These lines formed a 2d sketch of the propellers. The cylinder that was used to draw the propellers was then deleted. The 2d propellers were then extruded together and formed the basic look of the propellers.
Step 4: Moving Forward
To make the hover car move forward, a turbine was added. The outside shape of the turbine was made by drawing a circle standing vertically. The circle was then extruding. The back of the turbine was filleted to make it look more realistic. The turbines were made in the same way as the propellers were.
Step 5: Seating
The seats for this hover car were made by drawing a rectangle on each side of the seating space. These rectangles were then extruded upwards. Another rectangle was added on top of each of the first seating rectangles. These rectangles were then extruded up wards as the backs of the seats.
Step 6: Compartments
Hover cars along with cars today have consoles for the owner to store items such as CD's, iPods and other items. Consoles were added to this hover car by drawing a rectangle and then it was extruded upwards. The front of this rectangular prism was then fileted to round it off. This makes it look realistic. A gear box was also added the same way as the console was. A gear stick was added onto of the gear box be drawing a circle and extrude upwards. A larger circle was then drawn and extrude on top of the first cylinder.
Step 7: Adding Aerodynamics
To make the propellers work and allow the hover car to elevate off the ground, slants were added to each of the propellers. On the left side of each triangle shaped propeller, a slant was added. When the propellers spin anticlockwise, air will be forced on top of the propellers and then forced down the slants at a quicker speed then the air underneath the propellers. The air that is being forced down the slants lifts the hover car off the ground. The slants will also support the hover car while in the air.
Step 8: Wings
To give the hover car more support while in the air, small wings were added to the front of the hover car. These small wings are made the same way as wings on aeroplanes today. There is a curved slant at the back end of the wing. When air hits the front of the plane it travels over the top of the wings and then down the curve. The air heading down the curve travels quicker than the air underneath of the wing. This downward air pushes the hover car into the air as support to the propellers.
