Pulse 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 کاملToroidal 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 کاملOff-Design Performance Prediction of Jet Engines
In this paper it is attempted to predict the off-design performance of a jet engine. After a review of the governing equations, the off-design performance is investigated by two methods. In the first method, the component characteristic curves of the Gas Turbines are used. In the second method some design point parameters and the reference state conditions are employed. The results obtained by ...
متن کاملAIAA 2003-1171 Reactive Flow Phenomena in Pulse Detonation Engines
This paper describes oneand two-dimensional numerical simulations, with simplified as well as full reaction kinetics, of a single cycle pulse detonation engine (PDE). Focus of the present studies is on 1) the presence of a nozzle extension at the end of the tube, and its effect on performance parameters as well as noise characteristics, 2) critical “spark ignition” energies associated with the ...
