| 摘要 |
A two-phase shock wave generator including a combustion chamber including a first, combustion, portion having an input port and a second, detonation, portion downstream of the first portion and having an output aperture; an air-fuel supply line, operative to feed the input port with an air-fuel mixture, an igniter, associated with the air-fuel supply line, which ignites the air-fuel mixture in the supply line and initiates a burning front which propagates towards the input port and a turbulence stimulator, fixedly mounted in the combustion chamber, which enhances and controls burning of the air-fuel mixture and includes a first section, situated within the combustion portion of the combustion chamber and having a preselected first gas dynamic resistance and a second section, situated within the detonation portion of the combustion chamber and having a preselected second gas dynamic resistance, lower than the first resistance, wherein the first resistance is such that burning of the air-fuel mixture in the combustion portion yields a predetermined pressure level suitable for initiating detonation of the remaining air-fuel mixture, in the detonation portion, and wherein the second resistance supports continued detonation of the remaining air-fuel mixture in the detonation portion.
