Abstract: An improved slave propeller synchrophaser (l0) includes a first control (l4) responsive to a phase difference signal (28) and a phase difference reference signal (26) for providing a phase error signal (ll2) and for providing a propeller speed reference bias signal (40) for a speed governor (46), and also includes, according to the present invention, a second control (l2) responsive to the phase error signal (ll2) for providing an engine power reference bias signal (80) for an engine power control for providing a very limited amount of propeller fine speed control within the dead band of the propeller speed governor while at the same time substantially maintaining engine power at the commanded power level.
