FADEC Control Unit - CFM56-7B

A browser-based interactive dashboard that simulates a FADEC (Full Authority Digital Engine Control) panel for a CFM56-7B aircraft engine.

Assignment Requirements

• Title: Full Authority Digital Engine Control
• Objective: interpret real-time sensor data from changing air volumes and use FADEC diagnostic logic to decide whether the engine is Airworthy or requires maintenance
• Inputs:
  • Wa for air mass flow
  • Tamb for ambient temperature
  • N1 for fan speed
• Algorithm rule:
  • Golden Rule: every 15 units of air must provide 1 unit of fuel
  • Fuel flow formula: Wf = Wa / 15
• Throttle-to-Fuel map:
  • Throttle slider ranges from 0% to 100%
  • If throttle is above 50%, target N1 becomes 5,000 RPM
  • Below or equal to 50%, the system stays in STANDBY
  • FADEC checks the actual N1 and decides whether the fuel valve should open, close, hold, or reduce fuel during safety conditions
• Feedback loop:
  • Check whether added fuel increases engine speed
  • Check whether the engine is too hot
  • Reduce fuel when temperature is too high
• Software output:
  • Build the logic in a simple CBT or browser-based simulation
• Final hardware concept:
  • ECU or brain
  • Sensors or eyes
  • Actuators or hands

Overview

This project presents a futuristic aircraft engine monitoring interface with:

• Real-time sensor input controls
• Fuel flow calculation
• Throttle-to-fuel and N1 feedback logic
• Temperature warning states
• Engine status output: Airworthy, Caution, Standby, or Requires Maintenance
• Reset button for returning all values to default

Features

Feature	Description
Wa Slider	Air mass flow control in kg/s
Tamb Slider	Ambient temperature control in C
Throttle Slider	Engine input percentage (0-100%)
N1 Slider	Fan speed control in RPM
Fuel Flow	Live computation using Wf = Wa / 15
Fuel Valve	Open / Close / Hold / Reduce logic
Temperature	Warning and fault state detection
Log Ticker	Animated activity log
Fuel Map	Canvas-based fuel visualization
Reset	One-click return to default values

Logic Summary

• Fuel Flow = air mass flow divided by 15
• Target N1 = 5,000 RPM when throttle > 50%
• Standby = throttle <= 50%
• Valve Decision = compare actual N1 vs target when active
• Temperature States = Normal → Caution → Fault
• Safety Action = reduce fuel flow during overtemperature
