Problem StatementStephen Christiansen

• Design and fabricate a competitive car while keeping in compliance of the FSAE rules. These are some of the key concepts for the competition:

• High Strength (Durability)

• Low Weight (Improves braking, handling, and acceleration)

• Assembly (Low maintenance)

• Expense (Low production cost)

• Innovation (Engineering design challenge)

• Safety

Side PodsChristopher Caulkins

• Designed and fabricated side-pods

• A reversible female mold

• 4 ply of fiberglass using a cross pattern weave for torsional rigidity

• Left side pod houses cooling system

• Right side pod houses exhaust system

• Lower and more centered C.G. improves handling significantly

Nose ConeKevin Kelly

•Designed and fabricated nose cone

•Mixed 2-part expanding foam

•Carved/sanded away excess foam

•Laid 3 plys of fiberglass over mold

•70% weight reduction

•Lower mass allows for better acceleration,

braking, and handling

Body PanelsAaron Hopkins

• Designed and fabricated body panels

• Advanced vacuum bagging technique

• 4 ply fiberglass was used for body panels

• 10 ply fiberglass was used for underbody panels

• Female molds allowed a smooth finish on outside

• 63% weight reduction

• Less weight will help acceleration

Suspension and FrameAndrew Myers

• 1" Chromolly Steel tube frame

• Double wishbone suspension

• Fully adjustable camber, toe,

and caster angle

• Motion ratios: Front 1:1 Rear 1:1.25

• Custom front uprights and spindles

Brakes and ControlsThomas Guglielmo

• Fabricated rear control arms

• Added Anti-penetration bars for

driver safety

• Fabricated front & rear rockers

• Attached front push rods

• Mounted shocks and springs

• Assembled steering linkage

• Designed pedal assembly

• Dimensions, shapes, and materials put into SolidWorks program

• Appropriate loadings placed on parts to be tested

• Ran FEA to determine factor of safety

• Optimized parts to reduce weight while retaining desired factor of safety

SolidWorks ModelingKevin Kelly

Fuel SystemAndrew Rowe

• Fuel map from 2012 car improved

• Cured mid range surge

• 8% increase in power, expecting additional 13% with new manifold

FundraisingKamod Gautam

•Raising Canes Fundraiser (over $180)

•Panda Express Fundraiser (over $150)

•Upcoming fundraiser at two Skinny dip

locations (VB Blvd or Colley Ave)
