FIELD: machine building.
SUBSTANCE: pulsating jet engine contains a body, a combustion chamber with a nozzle, a system for supplying components to the combustion chamber and igniting the fuel mixture. Combustion chamber has an annular cross-section. Nozzle is made in the form of a bifilar spiral formed by spiral bands and lateral rings. Output of each helix is oriented in the direction opposite to the direction of rotation of the body.
EFFECT: invention is aimed at increasing the efficiency of combustion products exhaust and sucking the fuel mixture into the combustion chamber.
