Liquid rocket engine with regenerative cooling, successfully fired at 6 kN steady thrust, exceeding the 5 kN design target
Combined propulsion for runway takeoff. Jet engine for atmosphere, rocket ignition at altitude. No launch pad
Takeoff from a runway, reach the edge of space, return and land. Fly again within hours, not months
Real hardware, real data. Our engine completed its first hot-fire campaign with regenerative cooling holding at design parameters across every burn
Fuel channels in nozzle walls absorb heat. Thermal loads within design limits through every burn
Pintle injector: 30-100% thrust range. Trajectory control, fuel optimization, soft landing
Complex geometries, part consolidation. Design-print-test in days, not weeks
CFD surrogates for rapid iteration. ML test data analysis. AI structural optimization
Jet engine for runway takeoff and atmospheric cruise. Rocket engine activates at altitude for high-speed and suborbital missions. Returns and lands like an aircraft
Defense, science, commercial. A reusable vehicle that operates from any runway, reaches suborbital altitudes, and lands back for the next mission

Conceptual design. Configuration subject to development and funding.
Each step validates the next. Timeline depends on propulsion results and funding
No European country operates a reusable launch vehicle. Defense budgets are at historic highs. The infrastructure for responsive space access does not exist on this continent
Responsive launch from any military runway. Reconnaissance beyond air defense reach. Reusable, affordable, sovereign
Defense capabilities →NATO identified the capability gap. A reusable vehicle carrying test payloads at Mach 3 to 5 with post-flight hardware recovery

Reusable space access from any military runway, without dependence on fixed launch infrastructure
Rapid deployment from existing airfields. No fixed, targetable launch pads. The runway is the launch pad
Jet cruise for range. Rocket boost above 80,000 ft. Collect, return, land. Fly again
Test materials, sensors, systems at Mach 3 to 5. Post-flight recovery and inspection
A runway-operated vehicle launches from any suitable airfield. This is the difference between a capability that survives the first hours of a conflict and one that does not
A propulsion research project that outgrew the lab. A team of engineers who decided to build something that flies. The only company in the Czech Republic developing liquid rocket propulsion and reusable flight systems.
120+ aerospace companies. ESA member since 2008. EUSPA headquartered in Prague. Dense supplier network for propulsion, composites, avionics
Liquid rocket engine successfully test-fired. Regenerative cooling nominal. Thrust exceeding design target.
