Toroidal Imploding Detonation Wave Initiator for Pulse Detonation Engines
Imploding toroidal detonation waves were used to initiate detonations in propane–air and ethylene–air mixtures inside of a tube. The imploding wave was generated by an initiator consisting of an array of channels filled with acetylene–oxygen gas and ignited with a single spark. The initiator was designed as a low-drag initiator tube for use with pulse detonation engines. To detonate hydrocarbon...
متن کاملDetonation Initiation in a Tube via Imploding Toroidal Shock Waves
The effectiveness of imploding waves at detonation initiation of stoichiometric ethyleneand propane–oxygen– nitrogen mixtures in a tube was investigated. Implosions were driven by twice-shocked gas located at the end of a shock tube, and wave strength was varied to determine the critical conditions necessary for initiation as a function of diluent concentration for each fuel. Hydrocarbon–air mi...
متن کاملPulse Detonation Engines: Initiation, Propagation, and Performance
Research carried out from 2003-2005 at the Explosion Dynamics Laboratories at Caltech under an ONR contract has examined many issues critical to Pulse Detonation Engine (PDE) development. These include: detonation structure imaging using OH PLIF; a narrow channel facility for examining regular and irregular detonations; detonation diffraction; mechanism of soot track generation; fundamental and...
متن کاملMultidisciplinary Study of Pulse Detonation Engines
Research at the Explosion Dynamics Laboratories at Caltech over the past three years under an ONR contract has examined many issues critical to Pulse Detonation Engine (PDE) development. These include: fundamental and applied studies of detonation initiation; detonation cell width measurements to characterize fuels, including JP10; visualization of the reaction zone structure of propagating det...
متن کاملDetonation Initiation via Imploding Shock Waves
An imploding annular shock wave driven by a jet of air was used to initiate detonations inside a 76 mm diameter tube. The tube was filled with a test gas composed of either stoichiometric ethylene-oxygen or propane-oxygen diluted with nitrogen. The strength of the imploding shock wave and the sensitivity of the test gas were varied in an effort to find the minimum shock strength required for de...
