Who Are We?
• We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. • This is our third year entering the
competition, with our previous teams being very successful– winning the best rookie team and competing at the national competition.
![Page 3: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/3.jpg)
Meet The Team• LunAR comprises of six key members, all
with different roles which are adapted to their talents. We also have a support team of a further three members to ensure that we reach the highest level of success in the competition. These are the cool ones. The crème de le crème.• We are hoping to exceeded our predecessors
the regional competition in Exeter (on the 3rd of February) which will allow us to race at national level, and hopefully then at an international level.

Planning the Project
• Regular team meetings• Donny specifically allocated roles in order
to make sure that each of the members had an idea of what to do.• Gantt Chart
![Page 15: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/15.jpg)
Our GoalsShort-term goals:
• Establish a strong, professional image by production of business cards and presentations at school.• Plan effectively for a high
quality car design.• Produce a professional
sponsorship prospectus to attract possible sponsors.
Long-term goals:
• Sustain strong relationships with at least 3 sponsors
• To maintain a well-managed team image that will be built up in the early stages of the project.
• To design and manufacture a car ourselves which will race at under 1.15 seconds at the regional competitions.
![Page 16: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/16.jpg)
Projecting Risks
• Along with planning, we created a list of possible risks and area which could go wrong in our campaign, how they could impact on our success and also how they could be prevented. We used this as a means of checking our progress and it helped us to minimise possible risks as we had already taken steps to prevent them.

Wheel Design
• Balance between a low rolling resistance and stability• Optimum dimensions• Figure 1 shows our first design• Figure 2 shows the second design
[Figure 1] [Figure 2]
![Page 27: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/27.jpg)
Wheel Manufacture
• Accurate manufacture with smooth finish • Consistent surface means minimal
friction• Renishaw offered to allow us to use their
more accurate industry-standard CNC Lathes
![Page 28: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/28.jpg)
The Bearings
• Ceramic over steel bearings• Lighter, higher quality and faster spin• Boca bearings • 2 sets of fully ceramic radial bearing of
dimensions 4 x 10 x 4 (ID x OD x W) mm• Resulting in 80% less friction with a 3 to
10 times longer track life.
![Page 29: Regional Competition. Who Are We? We are LunAR, an ‘F1 in Schools’ competition team from The Crypt School, Gloucester. This is our third year entering.](https://reader030.fdocuments.us/reader030/viewer/2022032601/56649dd15503460f94ac763f/html5/thumbnails/29.jpg)
The Axles
Material: Weight: Frictional Coefficients:
Density (g/cm3):
Advantages: Disadvantages:
Steel 4.03±0.01g 0.78 7.90 Inexpensive, easily accessible, large supply in school, very strong
High density and therefore weighs a lot, warps easily, ‘Burrs’ created when cutting
Carbon Fibre
3.90±0.10g 0.65 1.80 Lightweight (low density), extremely strong, high tensile and compressive strength, stiff
Expensive, slightly flexible where large force exerted
• Comparison of recommended materials:
• We decided to use carbon fibre. • Saving weight will increase the velocity of
the car.

Finishing the car• Added cellulose sanding sealer to seal the pours in the
Balsa600 grit wet and dry sand paper and fine wire wool to remove and smooth out the finer impurities
• Added a bespoke amethyst base coat to prime the car• Added gold base coat to contrast the purple and to
make the purple pop• Added sparkling purple spray paint as top colouring
layer• Added clear lacquer to protect and maintain the finish
on the car• Sanded the car down with 800 grit sand paper very
lightly between each spray
