Solar Centaur Turboshaft engine test
December 2nd, 2009 | by cmotel |Caterpillar industrial turbine engine test at S&S Turbines outdoor test cell in FSJ, BC Canada. Dual air vane motor starters. Free power turbine. Journal bearings. A very different type of engine for our test cell, yet it passes with flying colors!

The only explanation I can offer is this:
The nominal speed of the free power turbine (n2) is 15,000 rpm.
I’m guessing that 300-800 rpm is so low on the range of the pickup that the readings may be a bit unstable.
On the other hand, for this test the power tubine has no load, so it could gain speed very quickly. But coastdown would be slower…

at 1:00, on the monitor, the n2 window is just bugging or why is it hopping?
