Claim 12:
13. A pulse combustor system with improved air intake and thrust generation, comprising:
a pulse combustor including at least a combustion chamber, an inlet pipe, an exhaust pipe, and a fuel injector for injecting fuel into the combustion chamber, and an ignition means for ignition of a combustible fuel and air mixture in the combustion chamber at least for starting the pulse combustor, with a first open end of the inlet pipe and a first open end of the exhaust pipe pointing in a first direction; and
a ram air intake assembly connected to the pulse combustor, with the ram air intake assembly including at least
a plenum having a first end connected to an inlet pipe end of the combustion chamber and extending therefrom in the first direction past the first open end of the inlet pipe to form a second open end,
a plurality of diffuser ducts connected to the plenum and each in fluid communication with the plenum and each having a first open end open to atmospheric air pointing in a second direction that is opposite to the first direction and having a first cross-sectional area, and each having a second open end having a cross-sectional area greater than the first open end of the respective diffuser duct, and connected to, and in fluid communication with, the plenum, and each having a diffuser duct body that has a divergent shape from the first open end of each respective diffuser duct to the second open end of each respective diffuser duct, and
an augmenter having a first open end connected to, and in fluid communication with, the second open end of the plenum and a second open end facing in the first direction and open to atmospheric air, and an augmenter body that diverges from the first open end of the augmenter to the second open end of the augmenter.
