FADEC — Full Authority Digital Engine Control

Digital Engine Management

Microprocessor-based closed-loop control managing fuel flow, compressor stall prevention, and ignition timing for optimal engine performance at all altitudes and conditions.

Thrust Vectoring Control

Precise thrust magnitude and direction control integrated with flight control systems to enhance UAV maneuverability, stability, and precision payload delivery.

Real-Time Health Monitoring

Continuous vibration, temperature, and pressure sensing with onboard diagnostics (OBD) providing engine health status, fault detection, and predictive maintenance alerts.

Fuel Optimization Engine

Adaptive fuel scheduling algorithms minimize specific fuel consumption (SFC) across all flight regimes, extending mission range and reducing operational costs.

Turbojet Engine Control Capabilities

Control Function	Description
Start-up Sequencing	Automated ignition, acceleration, and warm-up sequence with battery and APU pre-heat support
Idle Speed Regulation	Stable idle RPM control across -40°C to +85°C operating range
Acceleration / Deceleration	Slew-rate-limited throttle response preventing compressor surge and flameout
Max Continuous Thrust	Governed maximum thrust with EGT limiting for engine longevity
Emergency Shutdown	Failsafe overspeed, OAT overtemperature, and flameout detection with instant fuel cutoff
Afterburner Control (if equipped)	Plumbed fuel injection timing and exhaust nozzle actuation for augmented thrust modes
