Abstract: There is provided a magneto-hydrodynamic generator which utilizes pulsating combustion. The generator has a central combustion chamber and a radial expansion chamber annularly surrounding the combustion chamber and communicating with it. The expansion chamber is defined between two opposing walls. A combustible fuel mixture is introduced into the combustion chamber and pulsating combustion is initiated in the combustion chamber, so that gas flow in the expansion chamber fluctuates with time. Means are provided for ionizing gas in the expansion chamber, and further means are provided for applying an external magnetic field to the expansion chamber. Finally, electrically conductive means are provided for extracting electrical power from the ionized fluctuating gas flow in the expansion chamber.

First Claim:
Show all 24 claims
We claim:     1. A magneto-hydrodynamic generator utilizing pulsating combustion comprising:
  • first means defining a central combustion chamber and a radial expansion chamber annularly surrounding the combustion chamber and communicating therewith, the expansion chamber being defined between two opposing walls which converge in the direction away from the combustion chamber in order to preserve a substantially constant cross-sectional area at increasing radii, and thus preserve the volumetric requirement of an expanding shock wave,
  • second means for introducing a combustible fuel mixture into the combustion chamber,
  • third means for initiating pulsating combustion within said combustion chamber, such that gas flow in the expansion chamber fluctuates with time,
  • fourth means for ionizing gas in the expansion chamber,
  • fifth means for applying an external magnetic field to the expansion chamber,
  • and electrically conductive means for extracting electrical power from said ionized fluctuating gas flow in the expansion chamber.
