Abstract：

Sheet metal parts are widely used in aero-engines. With the development of advanced aero-engines in the direction of high thrust-to-weight ratio, low fuel consumption, long life and low cost, a large number of new materials, new integral and lightweight complex structures are used, and higher requirements and new challenges are put forward for sheet metal forming technology. Therefore, from the aspects of concept, method, equipment, application and development level, etc., the domestic and foreign development status of advanced forming technologies such as hydroforming and hot forming of key metal material sheet metal parts such as superalloy and titanium alloy were systematically sorted out and summarized, and the gap and development needs of domestic sheet metal forming technology and equipment were analyzed compared with foreign countries. The results show that China should continue to vigorously promote the research,development and investment of advanced forming process, equipment for complex sheet metal parts of aero-engines, improve the level of advanced forming technology for sheet metal parts, establish and improve technical standards and quality systems, give full play to market benefits and social efficiency, and realize the self-controllable forming technology and equipment of sheet metal parts.
