Experimental Investigation on the Performance of a Direct-connected Pulse Detonation Engine
摘要
Abstract
In order to predominate the performance of detonation initiation and propulsion, based on the direct connected test of a gasoline/air pulse detonation engine(PDE) mock-up, the corresponding detonation initiation and propulsion experiments at different operation frequencies are carried out. The results indicate that detona tions are fully developed quickly in the PDE mock-up at the operation frequency range of 0-35 Hz, in which the deflagration to detonation transition(DDT) distance is about 0.9 m(from the ignition). As the operation fre quency increases, the PDE average thrust increases linearly while the increasing slope decreases slightly. The volume specific impulse and mixture specific impulse are of the similar change trend with the operation frequen cy. The maximum values of volume specific impulse and mixture specific impulse are both obtained at the opera tion frequency of 25 Hz. Meanwhile, the fuel specific impulse increases dramatically and the specific fuel con sumption decreases gradually. When the operation frequency exceeds 25 Hz, the fuel specific impulse and spe cific fuel consumption changs slightly.关键词
