Sean and Admin, I’m no GE YF-120 expert, but I’d hazard a guess that what you’re both thinking is the first stage, is probably a set of vanes (which can be either static or likely in this case, variable), which are used to help shape the airflow into the first compressor stage (like the F110 and F404)
That however does make it easier to screw yourself up on the first stage! Put your fingers in, spin the stage, get them caught between fixed vanes and moving compressor will probably put at the least a small pause in your concert pianist career.
The perspex tho, as Admin points out, is there to stop that – and to stop ppl putting ‘stuff’ in there and to seal the internals fairly air tight (perpex on both ends, in case you didnt notice) to prevent or slow any oxidisation or degreneration of the guts…
What you’re seeing is the “2-dimensional thrust vectoring” module. (2D hence it’s square/rectangular appearance). This would be analogous to a drift car’s hydraulic e-brake, used to pitch/turn the car even farther than just turning around the corner. (i really hope you know what i’m saying lol). As the jet makes a turn, the jet stream of the engine can be tilted slightly up, down, left, or right. This gives pilots advantages in dog fighting situations.
interesting, is that the radar blocker on the front end? it looks static.
What, you mean the sheet of plexiglass? It’s there to keep morons from sticking fingers into the turbines and chopping them off.
