Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] The present invention is an independent arched high-low temperature connection structure with support, which is characterized by primary supporting beam 1, secondary arc supporting beam 2, secondary bottom supporting beam 3, arched connecting beam 4, and tail end support Beam 5, supporting beam overhanging side bolt foot 6, supporting beam overhanging side bolt platform 7, non-supporting beam overhanging side bolt foot 8.

[0024] Each of the primary support beams 1 is respectively connected to three secondary arc support beams 2 and three secondary bottom support beams 3. There are two primary support beams 1 in total, and the two ends of each primary support beam 1 are respectively located at the secondary The intersection of the arc support beam 2 and the bottom three support beams 3 forms a certain angle with the vertical direction. The tw...

Abstract

An independent arched high-low temperature connection structure with support, which is a left-right symmetrical structure, and the left and right structures are the same, including the main supporting beams, the secondary arc supporting beams, the secondary bottom supporting beams, Arched connecting beams, end support beams, outrigger side bolt feet for support beams, outrigger side bolt tables for support beams, and outboard side bolt feet for unsupported beams. The bolt feet on the outrigger side of the supporting beam and the bolt platform on the outrigger side of the supporting beam are located at the high temperature end, and the bolt feet on the outreaching side of the unsupported beam are located at the low temperature end. Among them, the secondary supporting beam transmits the load to the primary supporting beam; the arched connecting beam is the main part of the connection, and also the main transition part of the high temperature end and the low temperature end. The present invention adopts wedge-shaped bolt connection and installation, which can effectively reduce the hot-end structure connected with the connecting piece, such as a ceramic cover, and effectively reduce the thermal mismatch phenomenon between the structures. At the same time, the support structure of the secondary beam can be added to improve the ability of the connector to withstand external force loads, and the overall strength of the high and low temperature connection structure can be enhanced.

Description

technical field [0001] The invention belongs to an arched belt-supported high-low temperature connection structure used for high-speed aircraft radome and arrow body metal structure, which can effectively reduce the excessive heat generated by the mismatch of thermal expansion coefficients of metal and ceramic cover under the condition of lightening the structure weight. Stress, and at the same time meet the bearing requirements of the aircraft ceramic cover under the action of aerodynamic load. Background technique [0002] During the flight of a high-speed aircraft, it faces an extreme aerodynamic thermal environment, and the temperature gradient between the various components of the aircraft is large. Therefore, it is often necessary to connect the high temperature end to the low temperature end, such as the connection between the radome and the airframe. At the same time, since the structure of the connector needs to meet the structural load-bearing requirements in a hi...
