Problems solved by technology

However, on the one hand, the existing atomization device has a complex structure, a large number of parts, and an extremely complicated gas and oil circuit system, and the processing and manufacturing costs are relatively high.
On the other hand, the structure size of the existing atomizing device is large, and a large nozzle mounting seat needs to be provided on the casing of the combustion chamber to install the atomizing device, which reduces the strength of the casing

Abstract

The disclosure provides a combustion chamber, an atomizing device thereof, and an aviation gas turbine engine, belonging to the technical field of aviation engines. The atomization device of the combustion chamber includes a main combustion stage, a pre-combustion stage and a nozzle assembly; the main combustion stage includes a main combustion stage inner sleeve and a main combustion stage outer sleeve sleeved on the main combustion stage inner sleeve; wherein , the inner sleeve of the main combustion stage is provided with a nozzle socket; the pre-combustion stage is penetrated in the inner sleeve of the main combustion stage; the nozzle assembly includes a pre-combustion stage nozzle and a main combustion stage nozzle; wherein, the main combustion stage The stage nozzle is arranged on the pre-combustion stage, and fits through the nozzle socket. The atomizing device can reduce the complexity of the combustion chamber and improve the strength of the combustion chamber.

Description

technical field [0001] The present disclosure relates to the technical field of aero-engines, in particular to a combustion chamber and an atomizing device thereof, and an aero-gas turbine engine. Background technique [0002] Lean fuel premixed pre-evaporative combustors are widely used in aviation gas turbine engines, which realize fuel supply and assist tissue combustion through atomization devices. However, on the one hand, the existing atomization device has a complex structure, a large number of parts, an extremely complicated gas circuit and oil circuit system, and high processing and manufacturing costs. On the other hand, the existing atomizing device has a large structural size, and a large nozzle mounting seat needs to be provided on the casing of the combustion chamber to install the atomizing device, which reduces the strength of the casing. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the backg...
