The program · Phase 0 under way

Engines first. Evidence at every step.

Our program moves in phases. Each phase ends with data that proves it worked, and the next phase starts only when it does.

  1. NOW

    Phase 0: Foundation

    • Combustor and injector design studies with ColibriV Design AI
    • Hydrogen safety framework and procedures
    • Test-site planning and supplier selection
    • Test-site selection and agreements in the Denver area

    PROVESA design ready to build, and a plan to test it safely.

  2. GATE → PHASE 1Test design selected and safety framework approved

  3. Phase 1: Test site & first fire

    • Planned hydrogen test facility at Denver International Airport
    • Hydrogen storage and handling with leak detection and emergency shutdown
    • Test stand and data acquisition
    • Cold-flow tests, then controlled ignition
    • Stable combustion across multiple operating points

    PROVESWe can handle and burn hydrogen safely and repeatably. Ends with Evidence Pack v1.

  4. GATE → PHASE 2Stable combustion and a complete test report

  5. Phase 2: Performance at pressure

    • Endurance testing
    • NOx and stability maps at pressure
    • Paid technology evaluation programs with airline and engine-maker partners
    • Certification evidence to aerospace standards

    PROVESPerformance and emissions data partners can evaluate.

  6. GATE → PHASE 3Emissions and stability data at pressure; partner evaluation under way

  7. Phase 3: Toward ground runs

    • Safety case documentation
    • Core-engine hydrogen ground-run plan
    • Flight-testbed planning with an approved design or production organization
    • Certification pathway with the FAA, and with EASA for international operation

    PROVESA credible path to an engine ground run and certification.

  8. GATE → PHASE 4Ground-run plan and certification pathway agreed

  9. Phase 4: Aircraft

    • Preliminary aircraft design and trade studies around our engines
    About our aircraft plans

The test site

Denver, Colorado.

We plan to build our hydrogen test facility at Denver International Airport, in the same region as our Lakewood engineering team. Keeping design and testing in one region shortens the loop from simulation to hardware, and keeps the program under one US regulatory jurisdiction.
