Abstract

The invention discloses a missile ceramic radome connecting structure, which comprises a ceramic radome and a connecting ring, and the inner wall of the ceramic radome is provided with a plurality ofnon-through pin holes, and the connecting ring is provided with a plurality of through pin holes; the connecting ring is fixedly connected with the ceramic radome through connecting glue and is fixedly connected with the ceramic radome through a pin; and the non-through pin holes are filled with glue liquid, glue overflowing holes are formed in the pins in the axial direction, and buffer glue layers are formed between the non-through pin holes and the pins after the glue liquid is solidified. According to the missile ceramic radome connecting structure, due to the fact that the mode of combining gluing and pin connection is adopted, the connecting strength of the ceramic radome and the connecting ring is enhanced, and it is guaranteed that the ceramic radome is not prone to embrittlement due to the fact that the buffering glue layer is formed between the non-through pin holes and the pins.

Description

technical field [0001] The invention relates to the technical field of missile radome, in particular to a missile ceramic radome connection structure. Background technique [0002] The radome of the missile is located at the forefront of the missile and needs to withstand the external load during flight and the thermal stress generated by aerodynamic heating. Usually, when the missile radome is made of high-temperature-resistant ceramic material, because the ceramic material is brittle, it is not suitable for drilling or slotting. For the connection between the projectiles, the force transmission between the connecting ring and the ceramic radome is relatively uniform and the structure is simple. [0003] However, the bonding method cannot eliminate the thermal stress caused by pneumatic heating. When the temperature of the bonding glue rises, the bonding performance will decrease, and in severe cases, the connection will even fail, and the bonding quality between the ceram...
