The invention provides a radiation cooling thrust chamber body part structure for a liquid rocket engine, and belongs to the technical field of liquid rocket engines. The radiation cooling thrust chamber body part structure for the liquid rocket engine comprises a thrust chamber body and a lattice structure layer, wherein the thrust chamber body comprises a combustion chamber and a spray pipe, thelattice structure layer is tightly attached to the thrust chamber body and is coated on the outer wall of the thrust chamber body. According to the lattice structure layer, the radiation heat exchange area of the outer wall of the thrust chamber body is increased, the radiation capability of the outer wall is improved, the thrust chamber body part temperature is facilitated to be reduced, and theworking reliability of a product is improved; meanwhile, the lattice structure layer increases the rigidity and strength of the thrust chamber body.
Description
technical field [0001] The invention relates to the technical field of liquid rocket engines, in particular to a radiation cooling thrust chamber body structure for liquid rocket engines. Background technique [0002] The radiation cooling of the liquid engine means that the gas transfers heat to the inner wall of the combustion chamber by convection and radiation, then to the outer wall of the combustion chamber by heat conduction, and finally radiates to the outer space through electromagnetic waves, and finally establishes heat balance, heat flow and wall temperature To achieve a balanced and stable state, improving the body radiation cooling capacity of the thrust chamber of the liquid engine will help to increase heat flow, reduce wall temperature, and improve engine reliability. [0003] Single-wall radiation-cooled body is a common structural form of liquid rocket engine thrust chamber, and it is mostly used in small-thrust space engines. Due to the limited heat diss...
