Gas Producer Tachometer (N1)
The pilot and gunner N1 tachometers display the RPM of the gas producer turbine speed in percent. The circuit is powered by the dc essential bus and protected by the GAS PROD circuit breaker.
|
106 Percent Maximum |
Volt - Ammeter Indicator
The pilot indicator displays the dc power voltage being supplied to the power distribution system. Simultaneous display of dc amperage is displayed only when the starter-generator is supplying power to the distribution system. The indicator right scale displays the voltage. The left scale displays the amperage. The circuit is powered by the dc essential bus and protected by the DCVM circuit breaker. There is no means of monitoring amperage load when dc power is supplied by the TRU. Overcharging of the battery or a thermal runaway condition could occur with no indication to the pilot.
|
Transient, operation in the yellow area may reduce generator life. |
Turbine Gas Temperature (TGT)
The pilot and gunner Turbine Gas Temperature (TGT) indicators displays the temperature in degrees celsius of the air in the first stage N2 nozzle. The circuits are powered by the dc essential bus and protected by the TGT IND circuit breaker.
|
400° C to 820° C Continuous Operations |
|
|
820° C to 880° C 30 Minute Limit (Military Power) |
|
|
880° C thru 950° C Transient for Starting and Acceleration (5 sec) |
|
950° C Maximum for Starting |
Transmission Oil Pressure / Temperature Indicator
The pilot indicator displays the pressure in psi and temperature in degrees celsius of the transmission oil. The electrical circuit is powered by the dc essential bus and protected by the TEMP IND ENG XMSN circuit breaker
| Transmission Oil Pressure | |

Engine Oil Pressure / Temperature Indicator
The pilot indicator displays the psi pressure of the oil at the pressure side of the oil pump and the temperature as degrees celsius of the oil at the engine oil inlet. The circuit is powered by the dc essential bus and protected by the TEMP IND ENG XMSN circuit breaker.
| Engine Oil Pressure | |
|---|---|
|
