Why making an aeroplane pylon is a true collaborative process
Aeroplane pylons keep the aircraft’s engines attached to its wings. Today, the development of such a critical component involves a collaborative chain of different specialists and suppliers, with Seco Tools playing a central role. Joe Gooding and Gary Meyers explain more.
Pylons are not the most noticeable part of an aircraft, but they are critical to keeping it off the ground and to keeping its passengers safe, because they are the components that attach the aircraft’s engines to its wings.
“There’s often one engine per wing, with four pylons per wing to attach the engine to it,” explains Joe Gooding, a UK-based Development Engineer for Seco Tools, who supports our customers in their projects, providing them with tooling and strategy suggestions on how to machine components. “The pylon itself is made from titanium that’s often forged and then machined down to the required size.”
“The aeroplane manufacturers are using titanium structural components as it’s the best material that gives them the safest option for those parts to be on an aircraft,” adds Joe’s colleague, Gary Meyers, Global Product Manager for Solid Milling, who’s based in Sweden.
“There are a lot of different Seco Tools product areas involved in making a pylon,” he continues. “From face milling to copy milling strategies, indexable tools versus solid carbide, drilling, reaming, and lately new barrel machining developments for the finishing of these components. These are tough parts that often have inconsistencies because they’ve been forged, plus deep pockets that are hard to reach. It’s safety-critical, so there are also very tight tolerances and finishing requirements too.”
