APU testing

Postby laser » 13 May 2017, 19:49

Hello, everybody,
I am at a university research project and we want to test an apu. The model is GTCP36-280 and is controlled by a FADEC. We have access to generic test cells. What is the problem with the fadec? Do we need a special test bench? I only have experience on testing engines that do not use a fadec.

Thanks!

If you have the schematics, you should be able to simulate all power sources and interfaces for the fadec. It must think its installed in an aircraft so all parameters it needs must be there. Or if you are able to re-program the fadec than you may fool it by simulating inputs it needs. (for example apu inlet door open , fuel valve open, fire handle not pulled etc..)

Thanks for your reply!
As i understand it means that we need the fadec to conduct the test?

yes the FADEC is the controller or the "boss". Without it it will not work. (Full Authority Digital Engine Control) the words say it all...

Ok this is clearly thanks for your help.
Do you happen to have the corresponding technical manual for the GTCP36-280 model, or do you know the reference?
That would really help to clear things out.

Thanks!!!
