Pressure gain
Energy release occurs through a supersonic wave rather than a constant-pressure flame.
Detonation propulsion systems
Propulsion built around the pressure wave.
SleipnirX is developing rotating detonation engines and in-engine thrust-vector control for the next generation of launch, high-speed and advanced aerospace platforms.

Why detonation
A different combustion architecture.
Conventional engines add heat through a comparatively slow flame. Detonation couples combustion to a shock wave, creating a pressure-gain cycle with the potential to improve efficiency and reduce system complexity.
Compact core
High energy-release density creates a path to smaller combustion hardware for a given mission.
Fewer mechanisms
Detonation architectures can reduce reliance on complex mechanical compression and moving assemblies.
Propulsion programmes
One technology stack. Two engine paths.
We lead with the rotating detonation engine while retaining pulse detonation as a future platform for mission-specific systems.

View RDE programme
Rotating detonation engine
A continuous detonation wave travels around an annular chamber, creating compact, high-density thrust with a steady overall output.
Programme 02 · Future
Pulse detonation engine
A cyclic architecture for applications where simplicity, pulsed operation and rapid mission-specific adaptation are valuable.
Engineering moat
Vector control designed into the combustor.
Instead of treating thrust vectoring only as an external mechanical system, SleipnirX is investigating controlled injection and chamber-pressure asymmetry inside the detonation engine itself.
- 01Commanded changes in injection distribution.
- 02Controlled azimuthal pressure asymmetry inside the chamber.
- 03A directed change in the resultant exhaust momentum.
