PROMETHEUS

We are a propulsion company.

Prometheus develops propulsion hardware. The computation, optimization and geometry exist to make better hardware in fewer iterations, and every result is proven in metal.

What we make

Rotating and thermal components, where geometry, stress, temperature and manufacturability all constrain each other.

  • Compressor and cold-section hardware

    Validated on the GE T700 cold-section module.

  • Impellers

    Centrifugal impellers with computed blade geometry, machined on 5-axis CNC.

  • Combustor assemblies

    A custom impeller and combustor assembly is under LOI with a design partner.

Materials we machine

Inconel 718
Nickel superalloy for hot-section and high-temperature parts
Ti-6Al-4V
Titanium alloy for high strength-to-weight rotating parts
6061-T6
Aluminium alloy for structures, housings and development hardware

Underneath propulsion programs, not competing with them.

We are not building another launch vehicle. We build the propulsion hardware, and the engineering and manufacturing capability behind it, that many different programs depend on.

The same pipeline that produced a turbomachinery cold section applies wherever propulsion hardware is limited by how quickly it can be designed, made and measured.

Applications

Marked by where each stands today.

  • Turbomachinery

    Compressor and cold-section hardware. Validated on the GE T700 cold-section module.

    Demonstrated

  • Impeller and combustor assemblies

    A custom impeller and combustor assembly is the subject of a signed LOI with a design partner.

    Under LOI

  • UAV propulsion

    Compact, high-performance rotating and thermal hardware for unmanned systems.

    Target

  • Defense propulsion

    Propulsion components for defense and aerospace programs, starting with our design partners.

    Target

  • Rocket propulsion components

    Turbomachinery and thermal components for rocket propulsion systems.

How we work with partners

The business starts with hardware and grows into production and platform access.

  1. 01

    Engineering and hardware

    Design partners bring a propulsion requirement; we deliver computed, machined and inspected hardware.

  2. 02

    Repeat production

    Validated parts move to repeat production for the same partners.

  3. 03

    Platform access

    Over time, deeper access to the engineering pipeline for partners with ongoing programs.

Stage one is where we are today, with design partners and signed LOIs. Stages two and three are the plan.
