WDS supports Bloodhound SSC project with high accuracy components

Published: 4 April 2014 - Rachael Morling

WDS is supplying the Bloodhound Project with vital components free of charge. Bespoke-built angle plates were manufactured for use as assembly jigs for the front and rear suspension to ensure that the vehicle is assembled with absolute precision.

Accuracy was extremely important throughout this project as the angle plates act as a datum point for the chassis build. Cast iron was used to create the angle plates because its stability meant that it would not flex or expand in the event of temperature fluctuations and which would in turn affect the overall performance of the car. WDS carried out all of the casting and machining in house meaning that it could ensure that the very high standards required were guaranteed. Once the work was complete the parts were supplied with a certificate of conformity to confirm that they met with the signed-off design.

Tony Parraman, head of supplier liaison observed “It’s impossible to overstate the importance of accuracy as we put the car together and the parts WDS has supplied will play a significant part in this. It’s great that a British company has been willing to support our efforts. This project wouldn’t have got any further than the drawing board without the support of our sponsors.’

Chris Putman, WDS sales and marketing director, added: "We supplied similar components to the team that built Thrust SSC and set the last record in 1997. When we heard that Andy Green was making another attempt at the record it seemed fitting that we offer the same support, so approached Bloodhound to see if they required our services. We understand the importance of precision in a project like this as the smallest misalignment could be catastrophic. Fortunately we are used to working to such fine tolerances due to the other industries that we work with."

Bloodhound SSC (Super Sonic Car) is a jet and rocket powered car designed to go at 1,000 mph (just over 1,600 kph). It has a slender body of approximately 14m length with two front wheels within the body and two rear wheels mounted externally within wheel fairings. It weighs over 7 tonnes and uses a Eurojet EJ200 jet engine and bespoke built rocket to produce more than 135,000 horsepower. A third engine, a 750hp 2.4 litre Cosworth CA2010 F1 V8, will also be used as an auxilliary power unit to drive the fuel pump for the rocket. Bloodhound SSC is a mix of car and aircraft technology, with the front half being a carbon fibre ‘monocoque’ like a racing car and the back half being a metallic framework and panels like an aircraft. The tolerances to which it's being designed can most closely be compared to the aerospace industry.

The Land Speed Record currently stands at 763.035mph over a one mile pass, which was set by Andy Green in Thrust SSC in 1997. This time Green has set his sights at achieving a speed of 1,000 miles plus in the Bloodhound SSC.
