Drawings

These three pages are my Drafting drawings for my personal rail car. I ended up going with the first one (Lamborghini Hurrican)

Construction

I placed a sketch picture on the right face, and I cut out the outline for it.

Next, I placed a sketch picture on the FRONT face, and I cut out the outline for it.

Lastly, I placed a sketch picture on the TOP face, and I cut out the outline for it.

I then placed another sketch picture and extruded the classic design on the Lamborghini Hurrican.

This is the cut for the CO2 Cartrage hole.

these are the holes I cut out for my wheels to sit in.

These are the Axle holes.

Lastly this is the Boss/Base and cut outs for the guide hole.

Flow sim #1

This is my fully assembled car, ready for the flow sim.

Here is the graph for drag.

Tis is the numerical value for lift and drag on my car.

Here is the graph for lift.

This is my first flow sim before making any changes.

Flow sim #2

This is my final improvement for the car, In the flow sim above there is a slight amount of turbulence on the back so this improvement might be able to cut that up.

Here is the new graph for drag.

This is the numerical value for lift and drag after the improvement.

Here is the new graph for lift.

The improvement of the drag is 24.02% and the improvement of the lift is 24.29%

This is my final flow sim for my rail car.

Printing

This is a gif of my test print in the slicer.

This is a gif of my final print in the slicer.

This is a picture of my test print working with the axles, guide hole, wheels, and Cartrage holes.

This is a photo of my final car, all assembled, and after post processing.

Race 1 vs Logen Grimm

This is the first photo of the race set up with Logens car.

This is the third photo of the race set up.

This is the first front view gif of the race.

This is the second photo of the race set up.

This is the fourth photo of the race set up.

This is the second back view gif of the race (slomo).

This is a photo of the starter for the race.

This is the fifth photo of the race set up.

This is the final time, I finished in 3.1 seconds.

Calculations

Using my time (3.1 seconds) and the length of the track (60 feet) I have calculated that my car went 19.35 fps or 13.32 mph.

Race 2 vs Matthew Yelverton

Race 3's layout with Matthews car.

These are the finishing times (mine on the left) my car finished in 3.583 seconds.

Here is the slo mo gif of the race.

Calculations

Using my time (3.583 seconds) and the length of the track (60 feet) I have calculated that my car went 16.75 fps or 11.42 mph.

Race 3 vs Colton Longobardi

Here is the layout with Coltons car.

Here are the races times (mine on the right) my car finished in 4.118 seconds.

Here is the gif of my third race.

Calculations

Using my time (4.118 seconds) and the length of the track (60 feet) I have calculated that my car went 14.57 fps or 9.93 mph.
