Combustion chamber (versions)

RU patent № 2120560

A combustion chamber and its version, which relate to rocket technology and, in particular, to liquid-propellant rocket engines, comprise an injector head and an oscillation suppressing device. In the first version the oscillation suppressing device is made perforated as a hollow thin-wall truncated conical body with uniformly arranged radial plates. In the second version the oscillation suppressing device is made as an insert installed right up to the injector face of the injector head with a perforated zone. The invention specifies dimensions of the hollow thin-wall truncated conical body and the insert. Such design of combustion chamber and its version leads to an increase in effectiveness of suppression of high-frequency oscillations.
