AI Technical Summary
Technical Problem
Traditional afterburner insulation panels are single-layer structures, which have poor insulation performance and are prone to deformation under thermal and aerodynamic loads, making installation difficult.
Method used
Design a double-layer structure for the heat insulation panel of the combustion chamber. The inner and outer layers are connected by fixed supports and rivets. The inner layer has spherical protrusions, and the outer layer is filled with heat insulation material. The mounting edge is provided with reinforcing protrusions to enhance the structural stability.
Benefits of technology
It improves the heat insulation effect and strengthens the installation edge to prevent deformation and ensure stability and heat insulation performance during long-term use.

Abstract
This application belongs to the field of aero-engine technology, and specifically relates to a double-layer structure afterburner heat insulation plate. The heat insulation plate is installed between the inner cone and the rear bearing cavity, isolating the rear bearing cavity from the inner cone's internal cavity. The heat insulation plate includes an inner layer, an outer layer, a skin, and a mounting edge. The mounting edge is located at the circumferential outer edge of the inner layer and has multiple circumferentially distributed through holes. The mounting edge is installed on the mounting edge of the bottom surface of the inner cone through these through holes. The outer layer is attached to the surface of the inner layer near the inner cone. The inner layer includes a spherical surface protruding into the inner cone's internal cavity. The afterburner heat insulation plate has a double-layer structure, and the cavity height is maintained by fixed supports and rivets. Heat insulation cotton is added to the double-layer cavity to enhance the heat insulation effect of the heat insulation plate.
