[0003]
In a typical sleeve and head plate structure, the head plate is mainly used to fix the swirler, while the sleeve is mainly used to adjust the recirculation zone, which makes the structure of the flame tube head slightly redundant and complicated
against
figure 2
The structure shown has the following defects: 1) The structure of the head plate and the sleeve, although the functions of each structure are obvious, it will obviously increase the weight of the combustion chamber
When the combustion chamber is burning, the flame in the main combustion zone and the flame in the corner recirculation zone interact with each other, which is prone to combustion instability and affects the safety of the combustion chamber

The cyclone sleeve and head plate integrated structure comprises a cone plate (6) and arc plates (7), a cyclone (2) is installed at an opening in the front end of the cone plate (6), the arc plates (7) are arranged on the upper portion and the lower portion of the rear end of the cone plate (6) respectively, the upper arc plate (7) is connected with the inner wall of an outer flame tube (4), and the lower arc plate (7) is connected with the inner wall of an inner flame tube (5). According to the invention, the structure is compact, the function integration of the sleeve and the head plate is realized, and the corner backflow area is optimized; by the adoption of the integrated head plate, the purposes of reducing the weight of the combustion chamber and improving the performance of the combustion chamber can be achieved.
Description
technical field [0001] The invention belongs to the technical field of aero-engine combustion chambers, and relates to an integrated structure of a swirler sleeve and a head plate. Background technique [0002] Combustion chambers of aero-engines generally include components such as swirlers and flame tubes. In addition to the cyclone body, the cyclone component also has a trumpet-shaped sleeve structure at the outlet of the cyclone, which plays a role in adjusting the size and position of the recirculation zone. The flame tube assembly includes the flame tube wall, head plate, cap, jet hole and other structures, wherein the head plate mainly plays the role of connecting the inner and outer flame tube walls and fixing the swirler. In addition, a splash baffle can be provided between the head plate and the sleeve according to the design requirements of the combustion chamber. Typical head plate, sleeve structure such as figure 1 shown. [0003] In a typical sleeve and hea...
