Problems solved by technology

[0002] The lean premixed flame in the combustion chamber of the power system such as aero-engine and gas turbine is easily affected by the air flow disturbance, and it is easy to form thermal coupling with the acoustic pulsation of the combustion chamber, resulting in unstable combustion, reducing the stable operating range of the engine, affecting the performance of the combustion chamber, and even affecting the performance of the combustion chamber. Structural damage caused by engine components

Abstract

The invention provides a swirler and a power system, and the swirler comprises a casing, a driving mechanism and a plurality of blades; the casing is provided with a first cover plate and a second cover plate which are oppositely arranged; each blade is provided with a rotating shaft, and the rotating shafts are rotationally connected with the first cover plate and the second cover plate; the driving mechanism is installed on the side, away from the second cover plate, of the first cover plate and provided with a plurality of output ends capable of rotating in a reciprocating mode, and each output end is correspondingly connected with the rotating shaft of one blade. According to the swirler, blade beating vibration and blade angle adjustability are achieved, the blade angle and the blade beating vibration frequency can be adjusted according to different working conditions of a combustion chamber, and therefore unstable combustion factors are actively restrained, and combustion stability is improved.

Description

technical field [0001] The present disclosure relates to the field of power systems, and in particular, to a cyclone and a power system. Background technique [0002] The lean premixed flame in the combustion chamber of power systems such as aero-engines and gas turbines is easily affected by airflow disturbance, and is easily thermally coupled with the acoustic pulsation of the combustion chamber, resulting in unstable combustion, reducing the stable operating range of the engine, affecting the performance of the combustion chamber, and even affecting the combustion chamber. Structural damage to engine components. SUMMARY OF THE INVENTION [0003] The present disclosure provides a swirler and a power system, which can realize blade beat vibration and blade angle adjustment, and can adjust the blade angle and blade beat vibration frequency according to different working conditions of the combustion chamber, thereby actively suppressing combustion instability factors and im...
