Full-flow staged combustion

The engine that redefines lift.

Aether Drive combines a full-flow staged-combustion cycle with additively manufactured turbomachinery to deliver more thrust, less complexity, and true reusability.

Capabilities

Built for reuse, tuned for performance.

Every subsystem is designed around the same goal: fly often, inspect fast, and fly again with minimal refurbishment.

01

Full-flow staged combustion

Both oxidizer and fuel-rich preburners drive the turbopumps before entering the main chamber, unlocking higher chamber pressure and cleaner exhaust.

02

Additive turbomachinery

Turbopumps, injectors, and manifolds are printed as single Inconel and copper-alloy units, cutting part count by 80% and improving reliability.

03

Throttled landing burns

Deep throttle range from 40% to 110% lets the same engine power ascent, entry, and precision touchdown without a dedicated landing motor.

04

Closed-loop health monitoring

Hundreds of embedded sensors feed a flight computer that adjusts mixture ratio, pump speed, and cooling in real time.

Performance envelope

Throttle deep. Burn long. Land precise.

Aether Drive is not optimized for a single point. Its wide throttle range and high expansion nozzle let it operate from sea-level ascent through vacuum coasting and powered descent.

40% throttle

Gentle terminal descent and hover capability.

110% throttle

Emergency ascent margin and gravity losses.

Technical data

Numbers worth knowing.

These figures represent the Aether Drive qualification baseline. Flight-proven variants may differ slightly based on vehicle integration and mission profile.
