Abstract

The invention belongs to the field of mechanical parts, and particularly relates to an exhaust steering support plate for an unloading cavity of an aero-engine. According to the technical scheme, the exhaust steering support plate for the unloading cavity of the aero-engine comprises a wedge-shaped shell and an installation base, the interior of the wedge-shaped shell is a cavity, the top of the wedge-shaped shell is a sealing face, the bottom of the wedge-shaped shell is an opening, the periphery of the wedge-shaped shell is a wide vertical face, a narrow vertical face and two wedge-shaped side molded faces, and densely distributed exhaust holes are formed in the narrow vertical surface and the two wedge-shaped side molded surfaces; and the installation base is arranged at the bottom of the wedge-shaped shell. According to the exhaust steering support plate for the unloading cavity of the aero-engine, high-temperature airflow in the inner cavity of a combustion chamber casing can be led out in the outer culvert airflow direction, airflow clusters are changed from being dense to being dispersed, high-temperature airflow and low-temperature airflow are mixed more evenly, damage to the outer culvert casing is prevented, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical components, and in particular relates to an exhaust steering support plate of an unloading chamber of an aero-engine. Background technique [0002] The combustion chamber casing of the aero-engine is equipped with an unloading cavity, which leads the airflow from the inner cavity to the outer culvert, balances the axial force of the rotor, and improves the reliability of the rotor. as attached figure 1 As shown, the existing unloading chamber is a straight row open type, and the outlet is not connected. 1. The low-temperature airflow is unevenly mixed, which causes the outer casing to be impacted by high-temperature heat load, causing damage and affecting the service life. Contents of the invention [0003] The invention provides an aero-engine unloading chamber exhaust turning support plate, which can lead the high-temperature air flow in the inner cavity of the combustion chamber casing along the d...
