Blindaje Fly-by-Wire con Triple Redundancia para Movilidad Aérea Urbana

eVTOLShield garantiza una estabilidad absoluta de control de vuelo para aeronaves multirrotor y de ala basculante, aislando al instante fallos en motores, amortiguando turbulencias y previniendo la pérdida de control bajo normas FAA 10^-9.

eVTOLShield Triple-Modular Redundant Architecture

Tri-Channel Voting, High-Bandwidth Actuator Bus & Real-Time Thrust Allocation

Central System: Tri-Channel Voter & Control Executive - 2-out-of-3 Fault Elimination Core

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)

Acomodación de Fallo Catastrófico a 300 Metros de Altitud

Unlike conventional airliners with aerodynamic gliding capability, multi-rotor eVTOLs rely entirely on continuous thrust to stay airborne. eVTOLShield deploys triple-modular redundant (TMR) flight control computers that detect motor failures in less than 5 milliseconds, dynamically redistributing thrust across remaining rotors to maintain stable, level flight.
