Embodiment Construction

[0020] The existing method of natural drying and bonding of tension and pressure pads requires a long drying period, and the bonding quality is not high. Large size radome. Aiming at the above problems, the present invention designs a method of accelerated bonding of tension pads suitable for large-load and large-size radome. It does not need to repeatedly disassemble and transport the large-size radome, and accelerates the drying of the adhesive on the spot in real time. Improve bonding quality and test efficiency.

[0021] Specifically, a method suitable for bonding large-size and large-load radome tension and pressure pads, the method includes the following steps:

[0022] First, design and fabricate a conformal loading tension pad in the test area of ​​the large-scale radome; in this step, the loading tension pad is completely attached to the loading area of ​​the radome to ensure the authenticity of the loading;

[0023] Second, clean and polish the large-scale radome t...

Abstract

The invention belongs to the technical field of aviation structure tests, and particularly relates to a method suitable for bonding a tension and compression pad of a large-size large-load radome. Themethod comprises the following steps that: 1, a matched loading tension and compression pad is designed in a large-size radome test area; 2, the bonding surface is cleaned and ground; 3, the bondingsurface is coated with an adhesive; 4, the surface adhesive is subjected to microwave heating and drying; 5, the tension and compression pad and the large-size radome are bonded; 6, a loading block isadopted for applying pressure to the tension and pressure pad in a loading area to guarantee sufficient bonding. In the method, when the tension and compression pad is bonded in the large-load and large-size radar radome test area, and in the gluing process, a microwave heating mode is adopted for conducting adhesive accelerated drying treatment on each bonding area, the heating temperature is flexibly adjusted according to different environment humidity and different adhesives, it is guaranteed that the adopted adhesives are fully suitable for the bonding conditions of the adhesives, the most ideal bonding state is achieved, and the bonding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aeronautical structure tests, and in particular relates to a method suitable for bonding tension and pressure pads of large-scale and large-load radomes. Background technique [0002] At this stage, with the development of aircraft avionics technology and the demand for high-performance combat, more and more electronic products such as radars and antennas are installed on various types of aircraft, and the size of aircraft radome is getting larger and larger. The requirement of maneuvering makes the load of the radome more and more heavy. How to carry out the static test of the large-size and large-load radome efficiently and easily is particularly important for the development of the entire aviation field. [0003] At present, the static test of the radome mainly uses the loading tension and pressure pad to transfer the test load, which depends on the force state of the radome in flight. The loading tens...
