SleipnirX is building a new class of high-efficiency detonation engines — Rotating and Pulse Detonation systems — engineered to deliver more thrust from less fuel, and to power everything from launch vehicles to next-generation air-breathing aircraft.
Engineered for the markets that move the world
Conventional jet and rocket engines rely on slow, constant-pressure deflagration. Detonation combustion releases energy through a supersonic pressure wave — a thermodynamically superior cycle that extracts more useful work from every kilogram of propellant.
We are advancing both leading approaches to pressure-gain combustion in parallel — choosing the right platform for each mission while building toward a unified detonation technology stack.
A cyclic detonation engine that delivers high specific impulse with a remarkably simple architecture. Underexplored commercially — and our fastest route to a demonstrable, fundable prototype.
A continuous detonation wave travels around an annular chamber, producing steady, compact, high-density thrust. The platform with the broadest long-term potential across launch and air-breathing systems.
A disciplined, milestone-driven path — starting with a focused detonation demonstrator and expanding toward air-breathing and advanced propulsion as the company matures.
Company formation, core team, market validation with launch and defense partners, and design of our first detonation demonstrator targeting our inaugural research grant.
Build and fire our first sub-scale engine on the test stand — characterising detonation stability, thrust and thermal performance to de-risk the architecture.
Partner with an established platform provider to fly the engine, generating the flight data needed to penetrate the propulsion market.
Adapt our detonation combustion core to replace conventional chambers in air-breathing engines — and begin foundational research into advanced and nuclear propulsion.
We're talking with investors, research bodies, launch providers and aerospace founders. If you're working on what flies next, let's talk.
