Just to share thought on making simple protection for the front section of the turbine. Happy compressor and no performance degrade. Good for grass field operation too.

Here's one on my PST J600 fitted on YA F16C. Cost around $1.50 and this screen actually saved the compressor wheel and the turbine after fatal crash of the F16.

Here's another one in Avonds F15. Simple, yet very effective.

where can I get one for my P80?

I believe they are tea bag strainers, do a search, its been gone over in good detail.

John
Can you please tell me the search word.

Hi Sabre!

Contact Peter at www.jetworld.com. They have a real good one for P-120 and P-80. I wrote a review in german jetmag.

JetCat USA has them for 20 bucks !

They are $25.95 at JetCat USA (includes shipping)... just bought one.

Hi Sabre,

Use keywords "FOD screen".

FOD stands for "Foreign Object Damage", in case you were wondering...

Bought mine at a kitchen store for 2 bucks. Cut off the handle and used RTV to stick it to the cover.
Cheapest thing I've done to a turbine..

Thanks to all

I found this thread posted originaly by cairoman for
a sheap smart solution.

HallO!

Just remember: With such a screen you have a loss in airflow of about 20-25%. That's qhy you need a bigger one. With our gas-engines we had the problem that they got too hot, with the turbine you may have a loss in power. With the www.jetworld.de screnn loss is at minimum. I could not measure the loss.

Greetings,

B777,

I have been trying to figure a way to fit a similar but non-metalic screen to the front of my RAM 500 for FOD protection.

Have you found or seen any evidence for EMI interference due to the metal to metal rubbing of your stainless screens on the front of the J600?

The other issue is of course, the size of the screen and airflow restriction. Would you think 8 mesh screening wire would be adequate, eg screen squares 1/8 of an inch (about 3 mm) on a side?

Hi

To prevent damages/scratches or interferrences dur to metal to metal rubbing, you use a simple rubber

You take the interior of a motobike wheel, cut a 1/3" "rubber-ring" and pull it on the turbine-frontcover. Than you put on your mesh and fix it with a second rubber.

For the e-starter you can use a bike-rubber..
Just like that:

And after installing, it just looks like that:

I didn't notice any RMI interference on my J600 with the screen fitted directly to the front cover. If you have that much metal-metal rubbing at the front of your turbine, its time for service! You should not have any vibration there.

No thrust lost or increase EGT with the small tea strainer fitted as shown in the first picture. The overall air flow into the turbine is still sufficient for normal operation. Actually, that particular F16C was lost due to structure failure at the right wing root during high speed pass (recorded 260kph).

When I used my tea strainer on my Tubines, I cut a piece of inner bicycle tubing into a ring, just like Jetcat does, with a smaller diameter hole than the starter motor. I then force fitted the rubber onto the motor which holds the strainer from slipping out.

I found this strainer/ sifter at Wal Mart. It is out of a flour sifter, looks like a large fruit can with a crank handle. $4.59. Fits perfectly on the P-120. Just pop out the handle and the strainer comes right out.
I used a Dremel to cut out the center hole for the starter, then soldered the edges. It is held in place with an automotive O-ring.

Takes two seconds to install or remove. Great idea and cheap insurance......

Ron, great minds think similarly! I found the same exact flour strainer at Walmart. But I just cut a hole in the middle and fit the appropriately sized grommet from the local hardware store into the hole, then slide the entire assembly onto the front of my TJT 3000. Perfect!
