Abstract

The invention provides a fuel manifold structure with centrifugal nozzles arranged in a crossed mode and relates to the field of aero-engine combustion chambers. The fuel manifold comprises an oil inlet pipe, a fuel manifold main body, a fuel oil branch pipe and centrifugal nozzles. According to the invention, the centrifugal nozzles are arranged layer by layer according to a certain rule, so thefuel injection area is greatly increased; the fuel oil atomization effect and the ignition performance of the fuel oil are also enhanced; different from the integrated design of a conventional fuel oil main pipe, the provided fuel manifold is formed by connecting the two semi-circular rings, so that the fuel manifold is convenient to disassemble, the problems of assembly, shape correction and assembly stress can be well solved, and inspection and maintenance of a combustion chamber are facilitated.

Description

technical field [0001] The invention belongs to the field of gas turbine engines, and in particular relates to a fuel oil main pipe with centrifugal nozzles in a novel arrangement. Background technique [0002] As one of the key components of the aero-engine, the combustor is located between the compressor and the turbine. Its function is to release the heat from the chemical energy of the fuel through combustion, and the heat generated will do work and be converted into the thrust of the engine. Therefore, The reliability, economy and life of the engine largely depend on the reliability and combustion efficiency of the combustion chamber, and in the combustion of the combustion chamber, the performance of the fuel supply device largely determines the combustion stability of the combustion chamber . [0003] In the working process of the combustion chamber of an aero-engine, it mainly relies on the fuel system to regulate and supply fuel, so the position of the fuel system ...
