WebApr 12, 2015 · Detonation in a racing engine is often the result of an overly aggressive tune-up – too much spark advance or not enough fuel. An early warning sign of detonation is a loss of crankcase vacuum. Trace detonation can hammer the cylinders hard enough to break the ring seal and cause crankcase vacuum to decrease. Retarding the timing or … WebRotating detonation engines (RDEs) are a promising technology for future propulsion and energy systems due to their high potential thermodynamic efficiencies and compact designs. However, the development of these devices into robust, reliable systems requires continued experimentation. In the Hanson Research Group, we work with engine experts ...

Stabilized detonation for hypersonic propulsion PNAS
WebThe higher the specific output (HP/in3) of the engine, the greater the sensitivity to detonation. An engine that is making 0.5 HP/in3 or less can sustain moderate levels of detonation without any damage; but an engine that is making 1.5 HP/in3, if it detonates, it will probably be damaged fairly quickly, here I mean within minutes. WebA pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of … WebApr 28, 2016 · In the example shown here there were a number of culprits that caused detonation to occur. First and foremost the compression ratio was too high for the pump gas available, it was well over 10:1 ... dedicated load balancer
