From design to manufacturing, aircraft engines integrate many cutting-edge technologies in modern industries, involving many fields such as gas dynamics, thermodynamics, combustion, heat transfer, structural mechanics, control science, material science and manufacturing technology. Aircraft engines need to work in a complex environment of high temperature, high pressure, high speed and high load. As various countries have higher and higher requirements for engine performance, in order to continuously improve the thrust-to-weight ratio of aircraft engines, the integral blade disk that integrates the engine blades and the engine blades has been designed and has become the core component of high thrust-to-weight ratio engines.
