NASA's rotating detonation rocket engine posts record test results

Combustion engines are tried and true, and however angry they might look and sound in a top-fuel dragster or space rocket booster, the combustion process of oxidizing fuel in air is relatively slow and predictable. Detonation, on the other hand, is as chaotic and destructive as it sounds. It's how most bombs work; you take an explosive fuel and hit it with a jolt of energy, and the chemical bonds holding each molecule together break apart, releasing wild amounts of energy in a shockwave that expands at supersonic speed.
