Description of the FADEC.
The FADEC (Full Authority Digital Engine Control) is a total system for the control
of a model gas turbine engine. Its main function is to control and regulate the electric
fuel pump, providing to the turbine engine the necessary amount of fuel for safe and
controlled operation, and to operate the ancillary devices for starting. The FADEC
measures the exhaust gas temperature, the relative position of the throttle stick and the
rotor speed. It monitors all of the controls necessary to guarantee that the engine stays
between the user defined parameters of operation, also providing failsafe shutdown of the
engine when it has detected any important anomaly. In order to make this assessment, the
FADEC has a rpm sensor, a thermocouple input, a throttle servo input, power connections
for the fuel pump, starter, glow plug, fuel and gas valves and the battery and a proprietary
digital port to program and read the engine data in real-time to a PC.
The measurements made by the FADEC are:
• Temperature of the exhaust gas
• Battery voltage
• Barttery current
• Width of the throttle pulses from the radio transmitter
• Engine rotor RPM
• Engine run time.
• External analog signal (airspeed sensor)

Features:

RPM input: Magnetic sensor up to 250.000 R.P.M. One pulse each turn.
•
Temperature range up to 1000ºC using a "K" type thermocouple
•
PWM control of 8192 levels for pump, glow plug and starter motor.
•
Adjustable power for the starter motor
•
Build-in electronic brake for the starter motor to help the clutch to disengage.
•
Blown glow-plug detector
•
Adjustable glow-plug power
•
Glow-plug temperature independent of the battery voltage
•
Elapsed engine run timers
•
Digital interface to a PC or to a handheld terminal.
•
Black box function. Record the engine measures each 0.5sec up to 52 minutes.
•
Radio link error counter
•
Battery usage counter in mA/h
•
Test functions for all connected devices.
•
Start modes: Manual, Auto Gas and Kerostart (1)
•
(1) Currently Xicoy Electronica offer 2 models of Fadec 10, one that allow manual and gas start, and the second,
that allow manual, gas and kerostart. In this manual all the comments about kerostart apply only to Kerostart
FADECs. Ignore them if you own a Gas start FADEC.
