The detail that caught me off guard first is the setting: a full static fire, held indoors, with the trailer parked on a concrete floor facing a concrete wall. The burn runs roughly thirteen seconds, and bright sparks reach the ground under the exhaust the whole time. Firing a motor inside a covered structure is a bold setup, and it seems to have worked.
The hardware around the motor is tidy. The stand is welded square steel tubing painted a red-orange shade, mounted on a steel frame fixed to a utility trailer. A front plate bolts onto the stand, and the motor carries its cylindrical casing with a green strip and a taped nozzle section. Thin electrical wires run along the frame for ignition and instrumentation, and a small action camera sits above the motor mount to record the run. A voice counts down from seven before ignition.
What stands out most is the exhaust: a bright, dense plume full of glowing sparks and embers. Sparks and light smoke show at the nozzle first, then a sustained high-pressure plume forms. After burnout the nozzle interior stays glowing. Alongside the firing, Space Concordia - Rocketry Division ran ignitor and cryo flow tests from January 2020, using water as a fuel analogue and liquid nitrogen as a safer stand-in for LOX.
One open point: the engine is described as a composite build of carbon fiber and fiberglass, but the chamber material was not specified separately. I would like that detail spelled out.
