Rotating detonation rocket engines (RDRE) are being developed with potential to be more efficient and safer than traditional rocket systems. Supercomputer simulations are helping guide their design.

Here’s how it works: Essentially, the rocket has to make thrust – that is, create force – by burning propellant to make hot gases. Then it shoots those hot gases out of a nozzle. It’s sort ...
