AvionicsTwins Virtual Iron Bird Architecture

Cycle-Accurate Processor Emulation, Virtual ARINC Switches & Fleet Telemetry Ingestion

Central System: Virtual Iron Bird Core - Distributed Co-Simulation Engine

Aviation Architecture Nodes

  • Cycle-Accurate DAL A Core Models
  • Simulated AFDX / CAN Bus Matrix
  • Automated Fault Injection Engine
  • 6-DOF Aerodynamic Flight Model
  • Fleet Health Predictive Analytics

Architectural Layers & Protocol Stacks

  • Processor & Bus Emulation Layer (QEMU-based Core Emulation / SystemC / Virtual AFDX Fabric): Microsecond-synchronized emulation of flight computer SoCs and ARINC 664 switches executing unchanged binary machine code.
  • High-Fidelity Flight Dynamics Simulation (Nonlinear Aerodynamic Co-Simulator / FMI / FMU 3.0 Standard): Physics-based 6 Degrees of Freedom (6-DOF) aerodynamic equations, atmospheric turbulence, and actuator load simulations.
  • Automated Fault & Anomaly Injection (Safety Fault Injection Harness / DO-178C Tool Qualification): Exhaustive generation of edge-case scenarios: frozen Pitot tubes, hydraulic pressure drops, lightning strikes, and crossbar deadlocks.
  • Fleet-Wide Predictive Maintenance Analytics (Digital Shadow Sync / Kalman Filtering / Residual Analysis): Continuous telemetry synchronization comparing real-world airborne flight data against twin predictions to detect mechanical wear.

Flight Telemetry Metrics: < 50 µs (Co-Simulation Time-Sync Skew) | 100x (Faster-than-Real-Time Regression Speed) | 10,000+ (Automated Edge Failure Scenarios Run) | 99.4% (Physical Flight Data Correlation Accuracy)

以信息物理孪生变革飞机研发

Traditional iron bird test rigs cost tens of millions of dollars, occupy vast hangars, and create scheduling bottlenecks for flight test engineers. AvionicsTwins replaces physical wiring looms and hardware boxes with cloud-native, real-time hardware-in-the-loop (HIL) simulators capable of running automated regressions across hundreds of virtual aircraft simultaneously.
