The invention relates to a manufacturing method for controlling the structure and the performance of a high-strength aluminum-zinc-magnesium-scandium alloy thick plate for spaceflight, in particular to a manufacturing method for controlling the structure and the performance of the high-strength aluminum-zinc-magnesium-scandium alloy thick plate for spaceflight. The invention aims to solve the problem of interlayer difference between the structure and the performance of the high-strength aluminum-zinc-magnesium-scandium alloy thick plate. The method comprises the steps of 1, ingot blank preparation; 2, ingot blank heating; 3, rolling the plate; 4, heating; and fifthly, the plate is finally rolled, and the aluminum-zinc-magnesium-scandium alloy rolled-state thick plate is obtained. The method is used for manufacturing the high-strength aluminum-zinc-magnesium-scandium alloy thick plate for the aerospace carrier. 一种控制航天用高强铝锌镁钪合金厚板组织和性能的制造方法，本发明涉及一种控制航天用高强铝锌镁钪合金厚板组织和性能的制造方法。本发明的目的是解决高强铝锌镁钪合金厚板组织和性能的层间差异性问题。方法：一、锭
