The mast torque measuring system was selected in order to optimize the performance
capability of the Bell 430 transmission, enabling the pilot to use the maximum power
to the main rotor for whatever ambient situational conditions exist (i.e., pressure altitude,
temperature, relative wind, etc.). Sensing elements [strain gages] are incorporated in
each of the transmission lift links. Measurement is accomplished by comparing the
difference between each lift link's electronic signal. The four signals are conditioned,
processed, and displayed on the IIDS [Integrated Instrument Display System] .
MAST TORQUE INDICATION
TRANSMISSION POWER RATING
The primary reference to power levels is through torque based loads in the transmission
struts with both engines operating. When one engine is inoperative, the reference is to
transmission input power.
Transmission power ratings at 100% rotor speed
(9598 rpm N2) are:
One Engine Inoperative (OEI)
(transmission input limit)
30 seconds 844 shp[629 kW]
2.0 minutes 811 shp[605 kW]
continuous 714 shp[532 kW]
All Engines Operating (AEO)
(main rotor mast limit)
takeoff (5 minutes) 1045 rhp[779 kW]
maximum continuous 989 rhp[738 kw]
