We specifically look at how air and oil flow through the transmissions and core of an aeroengine, from the bearings and injectors, through the gears, onto the engine walls and into the sump, ensuring they are all properly lubricated and cooled.
This is particularly important because these transmission elements are placed under a lot of duress in a bid to derive maximum performance from the engine cycle. Temperatures, pressures and engine speeds are getting far greater and service intervals longer.
If you look at the way engines have been designed over the past 30-40 plus years, it has very much been reliant on inherited methods and knowledge, what you could call "pedigree" and a strong element of testing. Now the emphasis is on trying to design things right first time using numerical tools.
I work on those computer simulations, providing analysis that can ultimately reduce the number of design iterations, to accelerate the time to production and reduce cost.
When you’re trying to push the envelope, with ever greater efficiency levels and onto new architectures, simulation can offer key insights.
