ARIS Completes Development of PEGASUS Gen1 Rotating Detonation Engine with Advanced Manufacturing Components
ARIS has completed the PEGASUS Gen1 rotating detonation engine, with cold flow testing ongoing and a first firing scheduled. Two engine variants were developed: Gen1-C, featuring active water cooling, and Gen1-U, an uncooled version. Each engine aims to generate approximately 1 kN of thrust with detonation waves reaching 20,000 cycles per second. The Gen1-C engine was 3D printed using a copper-nickel-silicon alloy, with manufacturing support from various companies.

ARIS has finalized the PEGASUS Gen1 rotating detonation engine, which includes two variants: the actively cooled Gen1-C and the uncooled Gen1-U, both designed for 1 kN of thrust and capable of detonation waves at 20,000 cycles per second. The Gen1-C engine was produced using a copper-nickel-silicon alloy, supported by Feramic AG, while post-processing was conducted by LEUKA GmbH.
Additional materials were sourced from Schmelzmetall, Looser, and PDZ. Cold flow tests are currently underway, with the first firing expected to follow soon. This project builds on ARIS's previous propulsion work with the HEPHAESTUS engine series.
