Test Bed
Test Bed
(OP)
Hi,
I am trying to determine if it makes a difference for a test bed to have the following options? This test bed will test a turboshaft / turboprop engine.
The arrangements on the test bed are:
1) Engine -> Flywheel -> Dyno
2) Engine -> Dyno -> Flywheel
Would these setups affect the torque? Friction?
Would you have any references.
Thank you,
Gabriel

At another level, the flywheel could represent the normal load on the engine, so a direct coupling between the engine and the flywheel would make sense.
Ultimately, you need to determine, possibly by asking around, what the intent of the flywheel is. Only then could you ask where it's supposed to go.

Thanks guys!

A direct drive engine won't need any flywheel at all (T-56 as in a C-130). It can go direct into the dyno.

(1) is what is used on a typical IC engine, and (2) is effectively a chassis dyno.
(1) is nice because the flywheel decouples the two other shafts for TVs.
