ECU.
a brain for the fire
The engine control unit runs the VD-100 from the first spin to shutdown. It sequences the start, meters fuel to hold the commanded speed, and never lets exhaust temperature or rpm go past their limits, no matter what the throttle asks for. Its hardware design and firmware are our own.
Full authority: the pilot or autopilot asks for thrust, the ECU decides how to deliver it safely.

Materials
STM32-class MCU
Deterministic control loop, CAN and plenty of timers.
Conformal-coated PCB
Vibration, fuel vapour and temperature near the engine.
How it works
- 01
Start sequence
Starter spin-up, ignition, fuel ramp, light-off detection, self-sustain.
- 02
Run
Throttle maps to rpm target; PID with fuel-flow limits for surge margin.
- 03
Protect
Over-temperature, over-speed and flame-out detection with safe shutdown.
- 04
Cool-down
Starter motors the engine after shutdown to protect bearings.
- 05
Log
Every run logged for health monitoring and test analysis.
and then we check it
- Hardware-in-the-loop tests
- Sensor fault injection
- Environmental & vibration testing
