Title: Torque and RPM
Post by: Pei on July 08, 2002, 04:33:52 PM
I noticed this a few times now when I've forgotten to set the rpm/pitch to max at take off after landing my last sortie:

It seem to that the tendancy for the a/c to twist at take off (i.e. torque, p-factor and gyroscopic effect) is much greater at low rpm than high rpm.

Has anyone else noticed this (or have I been smoking crack again)?

Also is this the expected effect of low rpm on takeoff (it seems to me that all these effects would be reduced with low rpm)?

Low RPM -> Less Thrust -> Less Propwash -> Less Effectiveness of Tail Surfaces

Maybe this effect is stronger than the decrease in the forces and moments generated by the engine and prop, at least in AH.
