Engine Architecture

Precision-Engineered. Commercially Sourced.

The PSGI-1A engine integrates a pressure-fed combustion cycle with COTS-qualified injector assemblies, turbopump-adjacent feed systems, and a regeneratively cooled nozzle. The architecture eliminates single-source dependencies while maintaining performance margins consistent with heritage liquid propulsion systems.

Test Campaign

Validated Through Fire.

14 hot-fire tests completed across 3 test campaigns. Data confirms performance margins, thermal stability, and restart capability.

Test fire campaign 1
CAMPAIGN 1

Campaign 1 — Initial ignition sequence, 3.2-second burn duration. Chamber pressure nominal at 847 psia.

Test fire campaign 2
CAMPAIGN 2

Campaign 2 — Extended duration test, 12.8-second burn. Thermal soak confirmed within design limits.

Test fire campaign 3
CAMPAIGN 3

Campaign 3 — Full-duration acceptance test, 45-second burn. All performance parameters within 2% of predicted.
