description | The invention belongs to the technical field of cabin preparation, and particularly relates to a preparation method for changing a titanium alloy into a variable-wall thick hollow active cooling cabinwith an integrated structure function. According to the preparation method, a cylindrical tube blank is prepared by adopting a titanium alloy slab, and superplastic forming/diffusion bonding technology is adopt to form the variable-wall thick hollow active cooling cabin once, a 360-degree rotary cabin body is formed at one time through the method, and a hollow active cooling channel is arranged inside, so that the part forming precision is high, the part integrity is good, and the part structure and the function integration are realized. Due to a hollow sandwich structure, the cooling structure hollow cabin provided by the method is high in strength rigidity and light in weight. Due to the active cooling structure, active cooling can be realized, a coolant can directly use fuel in a fueltank, the overall weight i |
