Marks On The Eurofighter - Why?

Tue Feb 10, 2004 8:56 am

Hi guys.

I you look at the side of the air intake on the Eurofighter EF-2000 Typoon in the photo below you'll see many black & white marks that have numbers beside them. As you can see, these marks are scattered all around in no particular order of arangement.

Does anyone know what these marks are for, and why they're scrambled around like they are?

They look like they're marking the location of bullet holes in the order that the Typoon was hit. I didn't know the EF-2000 had seen action!  Laugh out loud

PS, if you check, you'll see that the photographer would like to know the answer to this question too. Big grin

If I'm not mistaken those are reference points for taking photos of the plane in flight. There are pictures of the F/A-18E/F with the same marks.
Never take financial advice from co-workers.

Remember that the aircraft shown is a development aircraft. All sorts of parameters will need to be recorded. Those shown are datum points, unfortunately though I have no idea what they will be measuring.

This is one of the aircraft used in the air to air weapons trials if I'm not mistaken. The datum marks are probably for measuring the seperation parameters.

Hi guys.

Thanks for your answers.

Ok, so if these are datum marks because the fighter is still under development, do you think it's possible that they're measuring different weight & balance parameters based on what type of ordanance it's carrying (different weights) and what weapons stations they're located on (different balance), as well as external fuel tanks, etc?

Having some relevant experience, I can confirm that those marks are visual reference points for, among other things, separation trials. You’ll find’em plastered all over the stores to be released as well. It is harder than you’d think tracing the path of the released stores relative to ground and aircraft, as well as the path of the aircraft, with sufficient accuracy. That’s nothing I’m personally involved in though, so don’t ask.

Getting new stores certified is not something to be taken lightly.

Setting out to measure weight and balance visually would be a very interesting way of doing things...

Cheers,
Fred
I thought I was doing good trying to avoid those airport hotels... and look at me now.
