Claim 4:
5. 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 of the plenum,
a diffuser duct in fluid communication with the plenum having a first open end open to atmospheric air and pointing in a second direction that is opposite to the first direction and having a first cross-sectional area, a second open end having a cross-sectional area greater than the first open end of the diffuser duct, and connected to, and in fluid communication with, the plenum, and a diffuser duct body that has a divergent shape from the first open end of the diffuser duct to the second open end of the diffuser duct,
an augmenter having a first open end connected to, and in fluid communication with, the second open end of the plenum and the augmenter having 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.
