Pelican's Perch #43:
Detonation Myths

We've all been taught about detonation in piston aircraft engines. It's what occurs when combustion pressure and temperature get so high that the fuel/air mixture to explodes violently instead of burning smoothly, and it can destroy an engine in a matter of seconds. Right? Well, not exactly. AVweb's John Deakin reviews the latest research, and demonstrates that detonation occurs in various degrees much like icing and turbulence with the milder forms not being particularly harmful. Heavy detonation is definitely destructive, and the Pelican offers some concrete data on how to avoid it.
