Hello everyone,
Question, mainly to Leon:
What are the balance values the maintenance/overhaul
manual requires and what values to you go for and get?
I am doing Track &Balance on helicopters ocassionally
and virtually all tolerances are 0.2 IPS (inch per second acceleration), though
we try to get them as low as possible.
E.g. The cooling fan on a R-44, which is directly mounted
to the engine crankshaft (Lyc-540), I will get easily to 0.02, sometimes to
0.015 IPS.
Just wondered what a Rotary requires and what you
recommend.
Cheers,
Thomas J.
