Help required about Hydraulic Systems

Hi everyone. I know I haven’t posted in a while but I’ve been up to my eyes in Uni work.

I have a question / favour to ask you all: I’m currently working on a translation from Spanish to English about hydraulic fluids and hydraulic systems on commercial aircraft and I need a few parallel texts in English to check my terminology is correct (and make my bibliography look more impressive 😉 ). I have tried searching the net for articles but am really struggling.

Do any of you have any texts or know of any good websites that describe hydraulic fluids and systems as well as how they function. Just to put the pressure on a bit more, it needs to be in by thursday (aren’t I a typical student leaving everything util the last minute).

Any information would be VERY gratefully received.

Thanks
