This project explores a bench-scale, three-chamber pulsed combustion demonstrator that uses mechanical phase-locking instead of software timing or fast solenoid valves. Three identical steel chambers are arranged radially and fed sequentially from a common rail using a rotary aluminium disc valve. Ignition is indexed directly from valve position using Hall sensors, so fuel admission and ignition are physically tied to rotor phase rather than firmware.

Each chamber exhausts independently to reduce pressure coupling and flashback paths. The system is intended as an experimental platform, not a propulsion device, and is operated at low repetition rates suitable for controlled bench testing. Early validation relies primarily on video and audio evidence to study sequencing order, repeatability, misfires, and isolation before adding instrumentation.
The focus is on clarity and observability—understanding how simple multi-chamber pulsed combustion sequencing can be made without complex el
