Title (EN) AUTO-DRIVEN PLASMA ACTUATOR FOR TRANSITION FROM DEFLAGRATION TO DETONATION COMBUSTION REGIME AND METHOD
(FR) ACTIONNEUR À PLASMA AUTO-ENTRAÎNÉ POUR RÉGIME DE COMBUSTION DE TRANSITION DE DÉFLAGRATION À DÉTONATION ET PROCÉDÉ
Abstract:
(EN) An engine that uses detonation for generating energy includes a housing (300); an inlet (306) configured to inject a fuel mixture (304) into an ignition region (320) of the housing (300), the inlet being attached to the housing (300); an ignitor (324) located in the ignition region (320) and configured to ignite the fuel mixture (304); a deflagration to detonation, DDT, region (330) in fluid communication and downstream from the ignition region (320); a pair of electrodes (362) located in the DDT region (330) and configured to apply nanosecond repetitive voltage pulses to the DDT region (330); and a detonation region (340), within the housing (300), in fluid communication and downstream from the DDT region (330). The nanosecond repetitive voltage pulses generate a non-thermal plasma that transition a combustion front propagation through the housing (300) from a deflagration mode to a detonation mode.
(FR) La présente invention concerne un moteur qui utilise une détonation afin de générer de l'énergie, lequel moteur comprend un boîtier (300) ; une entrée (306) configurée pour injecter un mélange de carburant (304) dans une région d'allumage (320) du boîtier (300), l'entrée étant fixée au boîtier (300) ; un allumeur (324) situé dans la région d'allumage (320) et configuré pour allumer le mélange de carburant (304) ; une région de déflagration à la détonation, DDT, (330) en communication fluidique et en aval de la région d'allumage (320) ; une paire d'électrodes (362) situées dans la région DDT (330) et configurée pour appliquer des impulsions de tension répétitives de nanosecondes à la région DDT (330) ; et une région de détonation (340), à l'intérieur du boîtier (300), en communication fluidique et en aval de la région DDT (330). Les impulsions de tension répétitives de nanosecondes génèrent un plasma non thermique qui passe par une propagation avant de combustion à travers le boîtier (300) d'un mode de déflagration à un mode de détonation.
