Zusammenfassung:	The invention discloses a large-specification aluminum-lithium alloy spinning shell and an overall performance control heat treatment method. The method comprises the following steps: designing and preparing a 2195 aluminum-lithium alloy spinning shell structure; the 2195 aluminum lithium alloy spinning shell is fixedly installed on a heat treatment tool; and the 2195 aluminum lithium alloy spinning shell is subjected to heat treatment. According to the characteristics of a 2195 aluminum lithium alloy material and the structural characteristics of a large-specification ellipsoidal spinning shell component, the size of a spinning shell and a matched heat treatment tool are designed, heat treatment process parameters of the whole process of solid solution, quenching, aging and the like are cooperatively optimized, the solid solution strengthening effect and the precipitation strengthening effect can be fully exerted, and the heat treatment efficiency is improved. The grain structure and precipitated phase distr
