description	The invention discloses a solid engine overall performance rapid calculation method for heterogeneous scheme knowledge migration, and the method comprises the following steps: selecting a plurality of solid rocket engine design source tasks from a knowledge base based on a similarity measurement criterion; constructing a low-precision model of a target domain based on the selected source task, and optimizing the low-precision model; and quickly calculating the overall performance of the solid engine based on the optimized low-precision model. The method is applied to the technical field of solid engines, the knowledge is extracted from a solid rocket engine design library source domain, the approximate model based on knowledge migration is constructed to replace a conventional approximate model, priori knowledge is effectively utilized, a large amount of sampling and simulation calculation are avoided, the modeling efficiency is improved, and therefore initial calculation resources are saved. 本发明公开了一种异构方案知识迁移
