TECHNOLOGY DEMONSTRATOR / EPOCH ORBITS

PROJECT ZEORTH.

World's first actively cooled 3D-printed aerospike engine. Bimetallic LPBF architecture combining CuCrZrTi liner and Inconel 718 jacket with conformal regenerative cooling channels.

THE ENGINE, ON ITS TEST STAND.

Move across the figure, or use the arrow keys, to climb from sea level to 40 km and watch the exhaust plume and thrust change.

Illustrative. The engine drawing and the shock and plume structure are estimates built from analytical relations, not CFD or test data, and the figures shown are model assumptions rather than confirmed Zeorth values.
