Renishaw metal additive manufacturing optimises engine design

To optimise the design of its engine cylinders, Cobra Aero worked with Renishaw to gain expertise in AM. The company visited a Renishaw Additive Manufacturing Solutions Centre, USA, and collaborated with Renishaw engineers to use AM to improve the design of a cylinder for an unmanned aerial vehicle (UAV).

Using AM technology allowed Cobra Aero to design a lattice structure to increase airflow, it also allowed them to produce one solid, lightweight part.

Sean Hilbert, President of Cobra Aero explains: "Staying at the cutting edge of manufacturing is important to Cobra Aero. Investing in AM allows us to develop tools and new products for high value, small volume applications, speed up the manufacturing process and produce designs that would not be possible using conventional subtractive machining.

"We decided to redesign the cylinder because of its importance in an engine. Design changes to this part of the engine must happen rapidly and it is also a high value part, which is why we have chosen to additively manufacture this component. Improving the performance of the cylinder will also improve the overall performance of the engine."

Stephen Anderson, AM Business Development Manager at Renishaw Inc. explains: "By using metal additive manufacturing, Cobra Aero was able to design a part that was unique to the application. By using our laser powder bed fusion technology, Cobra Aero was able to produce a single part with complex lattice structures that performs better than conventional component manufacturing techniques."
