A six-layer flight engine controller operating from the vehicle's 48 V avionics bus. The board commands solenoid valves and igniters while acquiring differential sensors, RTDs, and pressure transducers used during engine start and shutdown. After major first-revision faults were found, I owned the electrical and PCB revision, led bring-up, and became the board's day-to-day operational owner.
Design Focus
- Audit and correct inherited schematic and pin-mapping errors
- Restore stable igniter power by correcting converter behavior and compensation
- Correct ADC signal polarity and digital boot-state conflicts
- Separate high-current actuation paths from low-level sensor acquisition
- Verify the revised board behaves predictably during engine-control operations
This case study is under construction; public evidence is focused on the revision story, layout, and 3D board view.
