“We’ve been doing it since the early 90s. “Drilling holes is not a new thing,” begins Manesh Pandya, CEO of Lancashire-based ELE Advanced Technologies. That coupled with technology advancements are ensuring solutions that work on paper can also be made possible on the shopfloor. The solution - drilled cooling holes - has been around for a while, but today developments in cooling hole geometry are enabling this to happen more efficiently. The nickel-based alloy material making up turbine components needs to withstand temperatures of up to 1,400ËšC, without melting. A turbine blade component with film cooling holesīut firstly, let’s start with a reminder on why the holes are so important. Producing these ‘cooling holes’ sounds simple, but it’s not as straight forward as you might initially think. It is amazing to note that these ‘hot end’ components operate at temperature above their melting point.ĮLE Advanced Technologies is pioneering new technology and techniques to precision engineer holes that help these components to keep their cool – and it involves combining hundreds of shapes and sizes of holes, each created by varying types of technology. Being responsible for extracting energy from the high temperature, high pressure gas produced by combustion, to generate enough force to lift an aircraft off the ground – they work hard. We all know that aircraft turbine blades by their very nature get hot. Producing complex turbine components for aero engines, ELE Advanced Technologies has developed novel cooling hole technology to improve engine performance.
