Understanding the risks in the aerospace supply chain

Posted by Geoff Haines on 15-Sep-2017 11:00:00

As consumers around the world are demanding greater access to air travel, this has led to orders for 38,000 new aircraft. Although this represents the potential for significant revenue, OEMs and suppliers face significant risks that they must overcome in order to develop these aircraft cost effectively and ensure a quick time to market. 

A major trigger of these risks is how OEMs are now tasking suppliers with designing aerospace parts in addition to manufacturing.

Topology Optimisation and 3D Printing

Posted by Andy Woodward on 26-Apr-2017 09:00:00

The use of FEA to design ‘optimal’ components has been around for nearly two decades.  In general terms it works by meshing an available volume for a part and then eating away at the space iteratively to leave just those bits of the mesh that are doing work while aiming at a target mass for the part, as in the examples below.

 

Using this method ‘raw’ it is easy to see how un-manufacturable designs can result, so much effort has been invested by software developers to place manufacturing constraints on the optimisation process to, for example, eliminate voids or undercuts in moulded parts.
