FOD Guards
When the use of FOD guards started I wasn't keen as the converted sieve looked cheap on aeroplanes where you could see the turbine. With ducted installations I started using them and I'm glad.
Over the last few weeks we have received a run of turbines with compressor damage where FOD's weren't fitted. Now JetCat have a nice moulded cover that looks good and supports the motor housing there is no excuse. People like Wren with the built in FOD lead the way and I think long term all manuafctures should do the same.
On my Inspiration I couldn't get a std FOD on the turbine as the turbine is already a bit long for the ducting, so I bought a cheap sieve and cut out the centre to glue into the removable inlet section. I'm glad I did as looking in the inlets after flying last weekend on our muddy field the pix shows the mud stuck to the screen.

RE: FOD Guards
Good point,
We offer a free F.O.D Guard with every Turbine that we sell ( Or a UBT bubble tank), and over the past 2 years we have gone through just over 300 ( of two different size) F.O.D's So it looks like the public are also embracing the protection.

RE: FOD Guards
I have used home made ones on my AMT Pegasus engines and have come to the conclusion that I will need to do the same on the Olympus in my UB. Bennie doesn't make them but I have found some great cooking sieves with the right depth and strength to do the job. Tom.

When I looked for FOD screens for my Olympus I was told that larger turbines do not tolerate airflow limitations imposed by FOD screens - is there any truth to this?

I've tried a home made, rather corse mesh FOD guard on my P180 with no increase in EGT or acceleration time. i.e. it works fine. After meeting Olivier "OLNICO" who has made quite a few test with P200's, I tried a std 160 eng. FOD guard from Ali. It worked as good as my home made one. Only marginal increase in EGT with <10C.
So I'll stick with the finer mesh as it seems not to impose any significant decrease in performance.
My 2 cents
