Architectural Layers & Protocol Stacks

  • FADEC High-Frequency Telemetry Ingestion (ARINC 429 to IP Gateway / Lossless Telemetry Compression / FADEC Adapter): Continuous real-time ingestion of 120+ engine parameters: N1/N2 rotor speeds, exhaust gas temperature (EGT), fuel flow, and variable bleed valve positions.
  • Gas Turbine Thermodynamic Cycle Simulation (Zero-D/1-D Gas Path Analysis / Extended Kalman Filter State Estimation): Physics-based thermodynamic modeling of the Brayton cycle calculating compressor efficiency drops, high-pressure turbine blade creep, and thermal stress.
  • Transonic Aerodynamic Drag Tracking (Euler Aerodynamic Estimator / Machine Learning Drag Penalty Correlator): Continuous evaluation of aircraft lift-to-drag (L/D) ratios against pristine delivery baselines, quantifying drag penalties from bug strikes, rivet gaps, and leading edge erosion.
  • In-Flight Trajectory & Cruise Optimization (Dynamic 4D Trajectory Solver / Satellite CPDLC Uplink / EFB App Interconnect): Broadcasting optimized step-climb altitudes and Cost Index (CI) speed recommendations directly to cockpit electronic flight bags (EFB) in flight.

Flight Telemetry Metrics: 3.8% (Average Fleet Fuel Savings) | ± 0.5°C (Exhaust Gas Temp (EGT) Accuracy) | 100% (FADEC Data Lossless Transmission) | 30 Days (Advance Engine Fault Warning Time)

Optimizing Modern Airplanes Bit by Bit, Flight by Flight

Every individual aircraft in a fleet flies through varying atmospheric humidity, volcanic aerosols, and thermal cycles, causing unique engine and aerodynamic degradation. AirplaneTwins creates a bespoke digital twin for each tail number, calculating optimal cruise altitudes and engine wash intervals based on real-time physics.
