Swirler for aero-engine combustion chamber

The invention relates to the technical field of aero-engines, and discloses a swirler for an aero-engine combustion chamber. According to the swirler, each radial blade is provided with a rotating end part and a swinging end part, so that the blades can rotate along with the change of pneumatic parameters of an inlet of the swirler. For example, when the pneumatic parameter at the inlet end of the swirler is increased, the pneumatic parameter at the inlet of the swirler is also increased, so that the sectional area of an airflow channel formed between adjacent radial blades is increased, the incident angle of airflow at the inlet of the swirler is reduced, and the rotational flow strength is reduced; when pneumatic parameters of an inlet of the swirler are reduced, the sectional area of an airflow channel between the radial blades is reduced, at the moment, the incident angle of airflow of the inlet of the swirler is gradually increased, the rotational flow strength of the swirler is gradually improved, and t
