Renishaw is contributing its knowledge in additive manufacturing to create key prototype parts for the Bloodhound SSC supersonic car, which will attempt to break the 1,000mph speed barrier during summer 2015.

One of the most critical components is the nose tip for the car, which will be the very first part to break through any new land speed record and is subject to forces as high as 12 tonnes per square metre.

To cope with such loadings, a prototype tip has been designed in titanium using the AM250 additive manufacturing machines and will be bonded to the Bloodhound SSC’s carbon-fibre monocoque body, which forms the front half of the car.

Renishaw is providing a manufacturing resource to the project team to produce the nose tip on its laser melting machines, which use an additive manufacturing process to fuse together very thin layers of fine metallic powders to form highly complex functional components. The prototype will be used by the Bloodhound team to evaluate possible manufacturing processes and to carry out further engineering analysis.

Key benefits of product application

  • The additive manufacturing process used to produce the nose tip provides the ability to create a hollow but highly rigid titanium structure. According to the lead engineer at Bloodhound SSC, machinining this component conventionally would be challenging, would result in design compromises and would waste as much as 95 per cent of the expensive raw material.
  • Renishaw’s laser melting machines utilise an additive manufacturing process to fuse together very thin layers of fine metallic powders to form highly complex functional components.
