WebTriple Oil Pressure Indicator Mast Moment Indicator. General. General The BO 105 is equipped with an hingeless rotor and therefore high bending moments on the rotor mast can occur. The pilot has to avoid extreme cyclic stick motions on the ground with the rotor turning. The bending of the rotor shaft is monitored by the mast moment indication ... WebThe indicator generates a carrier frequency which is supplied to the strain gauge bridge via the rotary transmitter. Bending moments of the rotor mast alter the resistance value of the strain gauge bridge. This modified signal is then returned through the rotary transmitter to the MM indicator where it is evaluated and then indicated by a ...
