Turbine Starting / Running
1. Prepare to start by completing the startup checklist (previously described on
page
5
).
2. Briefly hold the model upward, to ensure there is no residual fuel in the turbine.
3. Set the AUX switch to the
Off
position. All LED’s will be off.
4. Move the throttle trim lever to idle (maximum) position.
5. Set the AUX switch to the
Start/Standby
(middle) position.
6. If the throttle stick is not at the idle position, the LED’s will blink in a continuous
sequence of yellow to red to green. Bring the throttle stick to the idle position,
changing the LED blink sequence to green to red to yellow, continuously. The
turbine is now ready to start!
7. Advance the throttle stick to its maximum setting and the turbine will start.
8. Once the turbine begins to accelerate, the throttle stick can be returned to idle
position. As soon as the turbine stabilizes at idle speed, the green
OK
LED will
illuminate, indicating that thrust control is now handed over to the pilot. The throttle
stick must be in the idle position, for the green
OK
LED to illuminate.
When the throttle stick is set to the maximum position (Step 7 ÜBER), the ECU will
begin a fully automatic starting sequence. This starting sequence can be immediately
disengaged, by moving the AUX switch to the
Off
position.
After the start process is initiated, the following occurs:
1. The starting motor spins the turbine rotor up to approximately 2,500-3,500 RPM -
then the starting motor is stopped.
2. Next, the glow plug is switched on and the starting gas valve opened.
3. The speed of the turbine begins to fall slowly, while ignition normally occurs during
this period. Should ignition not occur, the starter will automatically make more
attempts. If the turbine does not ignite, during a 30-second period of attempts, the
process is aborted and the green
OK
LED will blink.
4. As soon as ignition occurs, the yellow
Standby/Manual
LED will illuminate and the
starting motor is re-engaged to accelerate the turbine. At approximately 5000 RPM,
the fuel pump switches on and the red
Pump running
LED illuminates.
5. Turbine speed will progressively increase until achieving stable speed. When the
turbine speed surpasses the idle RPM value, the starter motor disengages and the
yellow
Standby/Manual
LED goes out.
6. As the turbine approaches approximately 55,000 RPM, it will briefly stabilize, before
automatically decelerating to idle RPM.
7. When the turbine attains idle speed and the throttle stick is placed at idle position,
the green
OK
LED will illuminate, indicating that thrust control is now handed over to
the pilot.
