Aero-engine turbine blade large size molding

Recently, the 3D printing department of the company has carried out 3D printing and large size molding manufacturing of aeroengine turbine blades. Turbine is the component with the largest thermal and mechanical load in aero-engine, among which turbine blade is subjected to the impact of high temperature and high pressure gas after combustion in the engine cycle, and its manufacturing technology is also listed as the key technology of modern aero-engine. In order to improve turbine blade performance and service life, and then improve engine performance, the use of gas film cooling technology is typical, and at the same time, higher requirements are put forward for gas film hole processing technology. For this reason, the powder bed electron beam 3D printing (SEBM) gives full play to its advantages of vacuum integrated molding and realizes the large size molding of special-shaped gas film holes, which provides important technical support for the development of new aero-engine blades.
