A method for operating a pulse detonation system. The method includes providing a pulse detonation chamber including a plurality of detonation tubes extending therein, and detonating a mixture of fuel and air within each detonation tube such that at least a first tube is detonated at a different tim

대표청구항 ▼

1. A control system for a pulse detonation system including a plurality of detonation tubes and a pulse detonation chamber having an exhaust chamber and the plurality of detonation tubes disposed therein, said control system comprising a processor programmed to control detonation of a mixture of fuel and air within each detonation tube, such that at least a first detonation tube is detonated at a time that is different from a time of detonation of at least a second detonation tube, and at least one pressure sensor electrically coupled to said processor and configured to sense pressure within the exhaust chamber. 2. A control system in accordance with claim 1 further comprising a firing sub-system electrically coupled to said computer, said firing sub-system configured to supply each detonation tube with air and fuel, said firing system further configured to detonate a mixture of the air and fuel based on sensed pressures within the exhaust chamber. 3. A control system in accordance with claim 1 wherein said computer further programmed to control detonation of the detonation tubes such that a region of a first pressure wave is substantially aligned with a region of a second pressure wave, wherein the first pressure wave region has a reduced pressure relative to the second pressure wave region. 4. A pulse detonation system comprising:a pulse detonator comprising a plurality of detonation tubes extending at least partially within said pulse detonator;a detonation chamber comprising an exhaust chamber, said plurality of detonation tubes disposed within said detonation chamber; anda control system comprising a processor programmed to control detonation of a mixture of fuel and air within each said detonation tube such that at least a first detonation tube is detonated at a time that is different from a time of detonation of at least a second detonation tube, and at least one pressure sensor electrically coupled to said processor and configured to sense pressure within said exhaust chamber. 5. A pulse detonation system in accordance with claim 4 wherein said pulse detonator comprises an inner casing, and an outer casing substantially coaxial with said inner casing and spaced radially outwardly from said inner casing, said inner and outer casings defining said detonation chamber therebetween said control system further comprising a firing sub-system electrically coupled to said processor and configured to supply each said detonation tube with air and fuel, said firing system further configured to detonate a mixture of the air and fuel within said detonation tubes based on sensed pressure within said exhaust chamber. 6. A pulse detonation system in accordance with claim 4 wherein at least one detonation tube comprises a length that is unequal to a length of at least one other detonation tube. 7. A pulse detonation system in accordance with claim 4 wherein at least one detonation tube comprises a diameter that is unequal to a diameter of at least one other detonation tube. 8. A pulse detonation system in accordance with claim 4 wherein said computer configured to control detonation of said detonation tubes such that a region of a first pressure wave is substantially aligned with a region of a second pressure wave, wherein said first pressure wave region has a reduced pressure relative to said second pressure wave region. 9. A pulse detonation system in accordance with claim 4 wherein at least a portion of at least a third detonation tube is stacked radially outwardly from at least a portion of at least a fourth detonation tube, wherein said third detonation tube is adjacent said fourth detonation tube, within said detonator such that a first central axis of said third detonation tube is spaced radially outwardly from a second central axis of said adjacent fourth detonation tube.
