Jet II
Design & build a car to the highest level
Jet II
Aim & Intention
Concepts
The aim and intention of Jet II was to apply the knowledge gained from my placement at Red Bull to design a car using CAD software and to build it to the highest standard.
Jet II is a full carbon fibre monocoque construction. Not only is the construction stiff but with controlled use of materials, reduced weight by up to 40% when compared to Jet.
Holder of the all time Greenpower F24 and F24+ records and winner of every F24+ race in 2016. Despite new 2016 regulations designed to slow the cars, Jet II still managed to break many records.

Solid Edge
Design & Development
Jet II was designed within Siemens Solid Edge over the course of 8 months. During which time, the designs were refined with close to 100 different iterations. Limited amounts of CFD was also used to help refine the overall form.
The Solid Edge files were then used to build Jet II, from the machining of the tooling block patterns to the central bonding jig.
A top down modelling strategy was used to develop the components design within the organic body. This also included the design of jigs and tooling.
Winner of the Best Engineered Car 2015 & 2016 and the Siemens Design & Manufacturing award.

Composite applications
Cullimore Racing is always looking push the technical boundaries. An example of innovation applied in Jet II was the application of carbon fibre used in the construction of the wheels. Not only a new material but also new innovative processes and practices were developed. With 4 wheel braking and a composite driver cell, the design of Jet II strives to be above the minimum safety regulations.

3D Printed Composite Tooling
A relatively new consumer technology in 2015, a 3D printer was used to make tooling for composite parts. In this instance, wheel spats were moulded and then trimmed to shape.
Sections were printed individually and mounted to a board.
Wet layup carbon fibre being applied which was then vacuum bagged.
