Liquid collecting ring on body part of thrust chamber of liquid rocket engine

Abstract

The invention relates to a liquid collecting ring on the body part of a thrust chamber of a liquid rocket engine. The liquid collecting ring comprises an upper liquid collecting ring cover (1) and a lower liquid collecting ring cover (2), and a radial hole (7) and a collection slot (8) are formed in the lower liquid collecting ring cover (2). The cross section of the upper liquid collecting ring cover (1) takes the shape of an elliptical arc, and a concave slot is formed in the cross section of the lower liquid collecting ring cover (2). The upper liquid collecting ring cover (1) and the lowerliquid collecting ring cover (2) are connected to form a liquid collecting chamber (6), and the liquid collecting chamber (6) communicates with the collection slot (8) through the radial hole (7). The liquid collecting ring has the advantages of good flow equalization, small pressure loss and good strength and rigidity and can also solve the problem that the welding airtightness of a steel jacket(3) and the body part of the thrust chamber is poor in the prior art.

Description

technical field [0001] The invention relates to a liquid collecting ring of a thrust chamber body of a liquid rocket engine, belonging to the field of liquid rocket engines. Background technique [0002] As a key component of the thrust chamber, the liquid collection ring is used to collect and distribute propellants. The engine’s design requirements for the liquid collection ring of the thrust chamber mainly include three aspects: (1) The flow distribution of the propellant is uniform; (2) The pressure loss of the propellant is small; (3) For high-pressure engines, the liquid collection ring must also have excellent strength and rigidity. Especially for the liquid rocket engine thrust chamber body that relies on the uniform distribution of coolant flow for reliable cooling and thermal protection, the design of the liquid collector ring is directly related to whether the engine can work normally. [0003] In addition, for the body of the thrust chamber, the liquid collecti...
