Question about P&W R-1830-? and R-2000

Fri Oct 20, 2006 9:17 am

Would any of you enthusiasts know if a 2:1 gear reduction for an 1830 and an R2000 are interchangeable? I'm looking to fit the 1830 1.77:1 reduction to my R2000 Yak-3U. Tips are at .82Mach right now and am looking for closer to .90 @ 385 MPH.

Thanks,
Will

Hello Will,

Why would you want to run less blade angle?

Bring the .82Mach tip speed up to .90-.92.
