2 Blade Propeller Dynamic balancing
2 Blade Propeller Dynamic balancing
(OP)
Hi All
I'm trying to balance a small propeller using a vibration meter. Is there a way I can balance it using trial weight runs and without using phase measurements? Something similar to the 4 run method?
I'm trying to avoid the effort of trimming weights constantly to obtain the final solution.
thanks

Trial one Xgcm on blade 1 =>v1 (fiddle with X until v1 is about 50% or 150% of v2, ideally)
Trial two X gcm on blade2=>v2
If v2-v0=v0-v1 then the answer is obvious
If v2 and v1 are>>v0 then you should have used a different X
If v2 and v1 are roughly =v0 then you should have used a different X
If v2 or v1 are zero then the answer is obvious.
