But a new type of engine — called a rotating detonation engine — promises to make rockets not only more fuel-efficient but also more lightweight and less complicated to construct.

University of Washington researchers have developed a mathematical model that describes how rotating detonation engines work.

YouTube’s Warped Perception channel cut an Estes model rocket engine in half (something you definitely shouldn’t try at home) and constructed a special see-through housing so they could film ...

An European aerospace company claims to have developed the first aerospike methalox 3D-printed engine, which was recently tested at the German Aerospace Center.

Shown here is a one-eighth scale model of the NERVA (Nuclear Engine for Rocket Vehicle Application) nuclear rocket test engine on a movable stand equipped with rails. Originally conceived by the ...

The company was formed back in 2020 with the goal of making a sort of mutant rocket engine that pairs the benefits of a rotating detonation design (RDRE) with those of a ramjet.
