- The page says the Medusa igniter fired four times out of four; earlier designs reportedly succeeded only 0–33% of the time.
Field notes
Each project is presented with its propellant pair, cooling approach, static-fire record, team size, and his role. The Medusa section follows specific hardware through design and fabrication: nozzle cooling channels were assessed in RPA and ANSYS, while valve actuators moved from Inventor studies to fabricated parts. The pintle injector section reports cold-flow results against a target and says hot-fire testing is scheduled; it does not present that test as completed.
