FIELD: aviation and space vehicles. SUBSTANCE: proposed jet engine has combustion chamber, nozzle, combustion chamber fuel feed system and device for initiating fuel combustion and preparation of working medium, and housing of all these systems. Nozzle member - bell is located inside combustion chamber and is connected with combustion chamber through its wide part. Critical section of nozzle is opposite to combustion chamber bottom. Fuel lines are laid first to nozzle critical section, forming around nozzle heat exchange chamber of engine cooling system, and then into lower bell part of nozzle to mechanism providing injection of fuel into combustion chamber at level of connection of combustion chamber and nozzle. Engine nozzle can be made up of rings arranged one after the other coaxially and at a distance from each other. Clearances between nozzle rings provide passage of gases into nozzle space. Channels to feed air into combustion chamber are located at place of connection of combustion chamber and nozzle. Edges of nozzle can be curved forward to form air intake. EFFECT: reduced overall dimensions and weight of engine. 4 cl, 3 dwg
