Final Design

I started doing the 3Ds Max for our final design. I started by importing the autoCAD plan that I did so I can follow the dimensions. I actually had a hard time getting the pattern of the roof as it is quite hard to get the curves. This was my first time doing a vehicle using 3Ds Max and I was really afraid that it might not turn out to be as realistic. Another hard part was making the vehicle look streamline. The curves have to be obvious to show the streamline body. I had a hard time making choice for whether the material should be matte, pearl or glossy. You really have to imagine how each part will affect the design, be it good or bad.

Process of rendering

The fun thing of doing 3Ds Max is that you can play around with different kind of materials. You will also feel a great relieve after it turns out to be what you expect.

This is my final outcome of my final design. I make the backgrounds look like a sky to make it look like it is flying in the sky. I went to show the interior as it really gives people a feeling how seating in it feels like.

Choices of material for the final design

I wanted the vehicle to be built out of aluminium, copper, magnesium and chromium because those are a common type of metals use to made aeroplane as according to my source <http://www.ask.com/question/what-metals-are-aeroplanes-made-from>. 

For the seats, I imagine that the passengers have to take a very long flight as landing and taking off will take a longer time for a vehicle this size. So i picked leather to be the material for their seats so they will have a much comfortable ride. 

The entrance and exit for the plane, I intended to use sliding door as it will not take too much room. Unlike the pivot door.

Color

Before doing the 3Ds Max. We had a group discussion on what color to use. We listed out some color like light blue, blue, grey, black, white, beige, yellow, orange, red and purple. We then imagine the vehicle out using this color to see which color will suit the vehicle more. We wanted to use as little color as possible so the vehicle will not be a moving rainbow in the sky. One of my group mate suggest that we take out any color that is related to sky. So we took out the color, light blue, blue, purple and grey as she thinks that if the vehicle is to blend in with the sky, other airplanes in the sky will not be able to see it very clearly and chances of those two crushing into each other is very high. We are then left with white, beige, yellow, orange, red and black. We wanted something with light color so our design will not look too 'scary' to the passenger. We wanted them to know that they will have a safe trip to their destination. We took out red, yellow and orange as they resemble flame. We also took out black as that color means the evil to most people. We decided to use beige and white as our airplane color.

AutoCAD drawing

With all the dimensions decided, a visual imagination of how our vehicle should look like. We then decided to use AutoCAD and Autodesk 3Ds Max to make our final design.

The hard part of doing AutoCAD is turning our perspective imagination into the top plan, front plan and side plan.

Reason for the streamline body

We wanted our vehicle to be streamline body as we believe streamline body will make the vehicle go faster.

According to our research, <http://wiki.answers.com/Q/How_can_making_things_streamlined_make_them_go_faster?#slide=2>, making a vehicle streamline reduces the ar resistance on the object. So it will not have to work as hard at high speeds and can therefore go faster.

According to another source, <http://wiki.answers.com/Q/How_streamlining_affects_forces_and_speed_on_cars?#slide=2>, Streamlining is an application of fluid dynamics to an object in order to reduce its drag coefficient. The drag force on an object is determined by three things, the shape of the object, the fluid it's moving through, and how fast it is moving through that fluid. The idea of streamlining is to reduce the drag coefficient of a car by changing it's shape, thus reduces the amount of force the car has to fight against at a given speed or alternatively given the car's power allow it to go faster. It makes the car move easily through the air, which cuts down fuel consumtion. For race cars it gives more speed.

Added lightning proof feature

We added a new feature to our vehicle which is to make it lightning proof. We thought to ourselves that if our vehicle is to be in the sky most of the time, there would be chances that the vehicle will have to fly into thunder clouds.

According to our source <http://edition.cnn.com/2010/TRAVEL/08/17/planes.lightning.strikes/>, It's estimated that lightning strikes each plane in the U.S. commercial fleet about once a year without any serious consequences, according to Lightning Technologies Inc., a Massachusetts company that designs lightning protection for civilian and military aircraft. If a plane is struck by lightning, it will be require to land to avoid more damage. But there are report that one passenger was killed after the plane broke apart while trying to land in bad weather. 

This is the reason why we wanted to add lightning proof feature to our vehicle so it will not be required to land even if lightning struck it. 

Research on how the vehicle will look like

I drew sketches of aeroplane to get a rough idea of how the jet engine should look like and how long the wingspan should be.

I drew car to know how is a vehicle state to have streamline body.

I drew double decker bus to see how high one deck should be.

I also research on double decker car to get an idea for our design.

I went and discuss with my group mates about the dimensions of our vehicle. We concluded that it have a length of 20,000 millimetre, a height of 6000 millimetre and a width of 5180 millimetre. We also concluded that the wingspan have to be about 21,000 millimetre in order for the vehicle to be able to take flight.
