Abstract

FIELD: manufacture of engines; pulsating ramjet engines used as heat generators. SUBSTANCE: engine has inlet diffuser, liquid-propellant jet engine, ejector, prechamber diffuser, afterburner, nozzle and fuel circulating system. Inlet diffuser is provided with pulsating combustion chamber instead of liquid-propellant jet engine. Combustion chamber is provided with aerodynamic valve and cooling jacket. It ensures suction of air through inlet diffuser at zero velocity of incoming flow and generation of vapors of main fuel at cooling jacket outlet which are mixed in ejector and are burnt in afterburner, thus providing thrust. Engine may work on one-component low-grade propellant. Mixing chamber of ejector is made in form of cone for blowing the air. Use is made of pulse of gases from aerodynamic valve by means of gas deflector mounted in nose cone. EFFECT: simplified construction of booster, enhanced reliability, possibility of use of similar fuel both for booster and ramjet with ambient air used as oxidizer.

Изобретение относится к области двигателестроения, в частности к пульсирующим воздушно-реактивным двигателям, и может быть использовано в качестве теплогенератора. Техническая задача - упрощение конструкции стартового двигателя, обеспечение работы как стартового двигателя, так и основного прямоточного на одном и одинаковом горючем с использованием в качестве окислителя окружающего воздуха, повышение надежности. Сущность изобретения: комбинированный прямоточный воздушно-реактивный двигатель содержит входной диффузор, жидкостный реактивный двигатель, эжектор, предкамерный диффузор, камеру дожигания, сопло, систему циркуляции горючего, во входном диффузоре вместо жидкостного реактивного двигателя установлена камера пульсирующего горения с аэродинамическим клапаном и рубашкой охлаждения, обеспечивающая подсос воздуха через входной диффузор при нулевой скорости набегающего потока, получение паров основного горючего на выходе из рубашки охлаждения, которые, смешиваясь в эжекторе с воздухом, сгорают в камере дожигания и обеспечивают получение тяги. Работа двигателя обеспечивается на однокомпонентном низкосортном топливе, камера смешения эжектора имеет коническую форму; для наддува воздуха, поступающего во входной диффузор, используется импульс газов из аэродинамического клапана с помощью отражателя газов, устанавливаемого в носовом обтекателе.The invention relates to the field of engine building, in particular to pulsating jet engines, and can be used as a heat generator. The technical task is to simplify the design of the starting engine, ensuring the operation of both the starting engine and the main once-through on the same fuel with the use of ambient air as an oxidizer, and increasing reliability. The inventive combined ramjet engine contains an inlet diffuser, a liquid-propellant jet engine, an ejector, a pre-chamber diffuser, an afterburner, a nozzle, a fuel circulation system, and a pulsed combustion chamber with an aerodynamic valve and a cooling jacket is installed in the inlet diffuser instead of a liquid-propellant jet engine air intake through the inlet diffuser at zero free flow speed, obtaining the main fuel vapor at the outlet of the cooling jacket expectations, which are mixed in the ejector with air, burn in the afterburner and provide traction. The engine is provided on a single-component low-grade fuel, the mixing chamber of the ejector has a conical shape; For pressurization of air entering the inlet diffuser, a pulse of gases from the aerodynamic valve is used with the help of a gas reflector installed in the nose fairing.
