LEAP-1A26 Engine Model & Control

status license

About

A FlyByWire Repo focused on the analysis, development and full integration of a realistic CFM LEAP-1A26 engine model and control (FADEC).

Please be aware we are still within the assessment and analysis phase of this initiative, so no installations or integrations can be performed yet within the Sim.

Stay tuned for updates!

❌ Issue/ feature pending

⌛ Work in progress

Roadmap

Tentative roadmap is as follows (it will be updated accordingly):

  • Understand Asobo's Engine model approach (basically engines.cfg) ✔️
  • Gather data and information on the LEAP-1A (Official/ Unofficial) ✔️
  • Physical/ theoretical modeling ✔️

Engine Primary Parameter Modeling

  • N1 and N2 ⚠️
  • EGT ✔️
  • Fuel Flow ✔️

Engine Secondary Parameter Modeling

  • Oil Qty, Pressure and Temperature
  • Vibration Parameters
  • Nacelle Temperature

FADEC/ EEC

  • Start-up and Ignition
    • Auto ⌛
    • Manual
  • Thrust Limits ⌛
  • EGT and OAT Limiting
  • Fuel Injector/ Dumper ✔️
  • Idle Management
    • Minimum Idle ✔️
    • Approach Idle
  • Thrust Reverse Management

Visuals

  • Upper ECAM
    • Units (Metric & Imperial) ✔️
    • Overall Fidelity (i.e. N2 decimals above 100%)
  • Lower ECAM
    • Units (Metric & Imperial) ✔️
    • Engine Page Fidelity
    • Fuel Page Fidelity ⌛

Misc/ Non-Normal Ops

  • Independent Engine Control ✔️
  • Windmilling
  • Gravity Feeding
  • Engine Cycle and Wear

Requirements

  • Python code developed and ran in Jupyter Notebooks on python 3.8.3 for x64.
  • MSFS Converter developed with AutoHotKey 1.1.30 for x64
