1-Does the test bed mean test cell?
I am wondering about the 17 tests and hours on high power engine run stated by Hangar_RAT (or 45 minutes as stated by Swedish Steve)?
The engine that you want to install on aircraft is supposed to be good: I assume (I might be wrong?) this engine was overhauled or repaired and tested in test cell in engines shop especially if internal items of engine were replaced. Either the engine is overhauled/repaired or new, it will require only few tests (leak test, gen disconnect,...) and not hours of high power engine run. May be you are using engine aircraft run as a substitute to engine test cell?
I hope I can get some clarifications regarding this subject: I guess I am missing or mis-understanding something especially when it come to engines shop work and Hangar or line work.
2-When you are performing high power engine run on engine (mounted on wing) do you run the opposite engine?
3-Steve, what do you mean by GI/FI?
Feedback appreciated.
Thank you.
