apexlined Posted December 8, 2010 Share Posted December 8, 2010 Why synchophaser can be select to engine no 2 or no 3 (inboard engine) only? Why not engine no 1 or no 4 ? Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted December 8, 2010 Share Posted December 8, 2010 Only no.2 and no.3 are wired to the synchrophaser syetem to control the other props (be the master engine) Quote Link to comment Share on other sites More sharing options...
tenten Posted December 8, 2010 Share Posted December 8, 2010 Might be due to better stability of inboard engines to wing oscillation/vibration than outboard engines. Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted December 9, 2010 Share Posted December 9, 2010 Sorry for the short answer... good point being a fully cantilever wing (no support) the outboard engines are prone to vibration(wing flex) so at some level there would be an induced flux (VERY SMALL) but there. If the prop is moving up and down in the air, the load on the prop would be uneven and the speed (RPM) would vary, inducing a speed change (change in blade angle to gain relationship) command from the master.
