M1
Single-sector cold-flow + ignition; flashback margins characterized
Certification-Ready Stack
Technology
Hydrogen-combustion without cryogenics, engineered for certification and scale. We develop turbofans that burn compressed gaseous H₂ (350–700 bar) and a supporting stack—combustor, storage & delivery, AI-assisted software, and safety—to move from lab data to multi-country passenger operations.
Engines first. Aircraft family next. Designed to be certifiable, testable, and exportable across authorities.
Why Hydrogen Combustion Now
Battery energy density can’t meet turbofan payload–range at commercial scale today. Hydrogen combustion delivers jet-class thrust using proven turbomachinery while we drive NOx down and safety up. We start with gaseous H₂ to accelerate testing and reduce operational complexity—then scale.
No Cryogenics
Fewer ground constraints and faster iteration at 350–700 bar.
Known Physics
Build on turbofan architectures operators already understand.
Cert From Day One
Aligned to ARP4754A/ARP4761, DO-160, DO-178C.

Design Principles
We structure the program to generate evidence quickly and package it for certification across authorities and airports.
• Certification-ready: requirements → architecture → analysis → test → evidence.
- • Operationally pragmatic: fueling, ventilation, PRD, & maintenance for real airports.
- • Scalable: short-haul to multi-country aircraft family; shared core.
- • Safety first: fault containment, leak detection, graceful degradation.
- • Data-driven: every test point becomes a certification artifact.

FAQs
Is the aircraft electric?
No. We use hydrogen combustion in turbofans, not fuel cells/propellers.
Why gaseous H₂ instead of liquid?
It removes cryogenic complexity and accelerates testing/certification. Gaseous H₂ at 350–700 bar is a practical on-ramp for early deployments and real airport operations.
How do you manage NOx?
Combustor geometry and staging (lean-premix/micromix), mixing strategies, and control logic—validated by pressurized test data with emissions/stability maps.
Where do you operate?
We develop in Liberia, Costa Rica (LIR) to move fast, then export evidence and playbooks to partner airports and authorities for multi-country deployments.
What about safety?
PRD strategies, ventilation, purge, leak detection, interlocks; HAZOP/FMEA feed authority-specific means-of-compliance.
When flight?
Core-engine ground run precedes flight testbed work with DOA/ODA partners per roadmap.
