Aviation Architecture Nodes

• Channel A: Primary Compute Node
• Channel B: Dissimilar Compute Node
• Channel C: Backup Fallback Core
• Direct Rotor Inverter H-Bridge Gate
• Triplicated IMU & Air Data Sensors

Architectural Layers & Protocol Stacks

• Tri-Channel Voting & Hardware Dissimilarity (DO-254 DAL A Dissimilar Silicon / TMR Hardware Voter): Three independent flight computers running 2-out-of-3 bitwise voting, utilizing dissimilar microprocessors to eliminate common-cause silicon bugs.
• Instantaneous Rotor Failure Accommodation (Dynamic Control Allocation / Quadratic Programming Solver): Control allocation algorithms that redistribute rotational torque and lift across healthy rotors within 5ms of an inverter or motor loss.
• Hard Flight Envelope Protection Limits (Control Barrier Functions / Certified Invariant Envelopes): Mathematical barrier functions preventing pilot inputs or automated autopilots from exceeding maximum bank angles, pitch attitudes, or G-loads.
• Electromagnetic & Lightning Surge Shielding (RTCA DO-160G Section 22 Level 5 Lightning Hardening): Rugged galvanic isolation, optical sensor coupling, and surge arrestors certified against direct lightning strikes under DO-160G Section 22.

Flight Telemetry Metrics: < 5 ms (Rotor Failure Isolation & Re-trim Latency) | 10^-9 (Probability of Catastrophic In-Flight Loss) | DAL A (DO-254 and DO-178C Certification Level) | 100% (Aerodynamic Departure Prevention Rate)
