Abstract
A pulse combustor system for operating pulse combustors in anti-phase. The pulse combustor system includes two pulse combustors connected at their combustion chambers by a connecting tube. Each of the pulse combustors has a fundamental oscillation mode and one or more additional oscillation modes when operated in isolation. The connecting tube has a length corresponding to ¼ of the fundamental oscillation mode wavelength.
Claims19
A pulse combustor system, comprising:
- a first pulse combustor, comprising a first combustion chamber, a first inlet pipe, a first exhaust pipe, and a first fuel injector for injecting fuel into the first combustion chamber;
- a second pulse combustor, comprising a second combustion chamber, a second inlet pipe, a second exhaust pipe, and a second fuel injector for injecting fuel into the second combustion chamber, the first pulse combustor and the second pulse combustor having a fundamental oscillation mode and one or more additional oscillation modes when operated in isolation;
- and
- a tube connecting the first pulse combustor combustion chamber to the second pulse combustor combustion chamber, the tube having a length corresponding to ½ of the fundamental oscillation mode wavelength.

A method of reducing noise and/or vibration in a pulse combustor system, comprising:
- providing a first pulse combustor comprising a first combustion chamber, a first inlet pipe, a first exhaust pipe, and a first fuel injector for injecting fuel into the first combustion chamber;
- providing a second pulse combustor comprising a second combustion chamber, a second inlet pipe, a second exhaust pipe, and a second fuel injector for injecting fuel into the second combustion chamber, wherein the first pulse combustor and the second pulse combustor have a fundamental oscillation mode and one or more additional oscillation modes when operated in isolation;
- and
- connecting the first pulse combustor to the second pulse combustor by attaching a first end of a connecting tube to the first combustion chamber and a second end of the connecting tube to the second combustion chamber, wherein the connecting tube has a length corresponding to ½ of the fundamental oscillation mode wavelength.
