power performances T56-A-15 LFE (Serie III)


Recommended Posts

first of all I wish the whole community a nice and healthy 2016 ;)

A question,

related to the power performance; what is the difference between

  • a bare engine on a test stand
  • an engine in a nacelle on a test stand
  • an engine on wing
  1. installation effect?
  2. measurements?
  3. other influences? weather, wind, humidity
  4. ......

thx for coop, bob

Hi Bob, prosperous 2016 to you also.


Engine (power package) on test stand or aircraft match up within 1%, i.e. 98% on test stand will be around 97% on

the wing.


As to running on a dynamometer, we had some engines from RollsRoyce that came with dyno sheets. I was

pleasantly surprized when the performances came in within 2%


As to atmospheric effects: engines on cold wet days may be awesome, but the same older worn compressor

on a hot humid day looks like it has emphysema
