Architectural Layers & Protocol Stacks

• 6-DOF Real-Time Physics & Aerodynamics (High-Speed Real-Time Linux / FPGA Aerodynamic Solvers): Calculating aerodynamic lift, drag, ground effect, and atmospheric turbulence at 1,000 Hz with sub-millisecond determinism.
• Hardware Sensor & Bus Signal Emulation (ARINC 429 / MIL-STD-1553 / Analog Signal Generators): Converting simulated physics variables into real electrical voltages, synchro angles, and serial packets fed to the LRU.
• Automated Electrical & Bus Fault Injection (Fault Insertion Units (FIU) / High-Speed Solid-State Relays): Simulating lightning transients, broken sensor wires, stuck actuators, and corrupt bus packets during active flight.
• Virtual Cockpit & Telemetry Verification (Synthetic Vision Display Engine / Automated Test Executive): Rendering realistic visual scenes for test pilots while automated regression runners verify compliance criteria.
