METHOD FOR OPERATION OF SUPERSONIC PULSE ATHODYD AND SUPERSONIC PULSE ATHODYD Russian patent published in 2009 - IPC F02K7/02 

FIELD: engines and pumps.

SUBSTANCE: method for operation of supersonic pulse athodyd includes supply and combustion of fuel in supersonic flow in expanding channel of combustion chamber. Fuel supply and combustion is carried out in several expanding sections of combustion chamber in pulse periodic mode. Combustion chamber is made of expanding sections that are serially installed one after another with devices for pulse periodic supply of fuel into points of sections joint and via pylons that are available in flow of every section. Sections of combustion chamber are arranged so that inlet section of subsequent section is more than outlet section of the previous section. Amount and frequency of supplied fuel in every section of combustion chamber is specified based on condition of non-stationary flow supersonic speed maintenance in the whole of chamber channel.

EFFECT: invention is aimed at increase of pulse athodyd operation efficiency to increase Mach number of flight.
