(1)FADEC hardware components

  The main part is dealing with a computer chip can also be used. The main inputs are: the accelerator pedal signal, the speed sensor signal, temperature signal, the pressure sensor, vibration sensor signals, the signal flow sensor, flame detector signal, the switch command signal, position feedback signal, as well as from the other computer to get the look bus information.
  These received signal processors act accordingly, then the corresponding output control actuators, including: deflation, or who, guide vanes, the main fuel metering valve, fuel dispenser afterburner, afterburner fuel metering valves, vents, variable stator vane compressor, the signal to the flight control system.

Main FADEC control function
Start Phase control
 It have 2 type of this control: Starting on the ground; starting in the air.
   For Starting on the ground, its main function is just the starting on cold condition, oil keeping, and start flying process control
   For Starting in air, its main function is automatically start in the air, hit the air start, air and other process control manual start.
(2) start control key control principle, is divided into three parts:
Logical operations,
start calculating the amount of oil,
Troubleshooting
(3) main combustion chamber fuel flow control
The main executive body by the main fuel metering valve, solenoid valve and emergency valve and other control accessories transform the composition;
The main fuel metering control software module according to throttle position and engine condition lever to calculate the fuel supply;
Electronic controller hardware output signals corresponding to instructions; main fuel metering valve to achieve the fuel flow measurement.
(4) Critical area of the nozzle and nozzle control
Depending on the engine condition, the nozzle control module control software calculates the location and status corresponding to the nozzle,
Electronic controller will correspond to the signal transmission to the nozzle actuator servo valve, nozzle actuator electronic controller output in accordance with the instructions to complete the critical area of the control jet.
(5) Afterburner fuel flow control
Afterburner afterburner actuator is in the original pump regulator on the basis of composition, and retains the plunger, remove the regulator part, to increase the afterburner afterburner fuel metering valve and hydraulic locks and other components.
