SUPERSONIC RAMJET ENGINE TRACTION AND ECONOMIC CHARACTERISTICS INCREASING METHOD (OPTIONS) Russian patent published in 2019 - IPC F02K7/00 

FIELD: engines and pumps.

SUBSTANCE: supersonic ramjet engine traction and economic characteristics increasing method includes flowing into its flow path supersonic air stream compression with the air intake device multi-jerk braking surface, air flow into the combustion chamber supply through the flow path, the fuel into the combustion chamber supply and the fuel combustion products discharge through the jet nozzle. Also performing the air flow removal, and the air duct closing by the closing device. Removal is performed from the braking surface in front of the air intake device neck through the grid of holes and the air duct into the external air flow reduced pressure acting zone, after the static pressure increase in the air intake device neck. At that, the air flow part removal is carried out through the opening in the flow path wall at the combustion chamber input and the combustion chamber and the jet nozzle cavity. For the air duct closing device operation using the air flow increased static pressure at the combustion chamber input after the fuel ignition therein.

EFFECT: invention is aimed at the air from the air intake device removal communication channel closing device design simplification and the aircraft side wall additional heating elimination.
