Problems solved by technology

[0002] Compressors are the main components of aero-engines and gas turbines. The adjacent two-stage rotor disks are mostly connected by drums. The existing drums are mostly single-layer structures, and their strength reserves, especially circumferential stress reserves, are limited by current materials. It is difficult to adapt to the high-speed and high-temperature working environment of the current compressor rotor system, which limits the improvement of the performance of the compressor rotor system. In severe cases, it will be damaged, leading to catastrophic consequences

Abstract

The invention belongs to the technical field of compressor rotor wheel disc connection design, and specifically relates to a compressor rotor wheel disc connection structure. The compressor rotor wheel disc connection structure comprises a front-stage rotor wheel disc, a rear-stage rotor wheel disc, an outer drum and an inner drum, wherein the rear-stage rotor wheel disc is adjacent to the front-stage rotor wheel disc, the outer drum is arranged between the front-stage rotor wheel disc and the rear-stage rotor wheel disc, one end of the outer drum is connected with the front-stage rotor wheeldisc, and the other end of the outer drum is connected with the rear-stage rotor wheel disc; and the inner drum is located on the inner side of the outer drum, one end of the inner drum is connected with the front-stage rotor wheel disc, and the other end of the inner drum is connected with the rear-stage rotor wheel disc. In addition, the invention relates to a drum structure including the outerdrum and the inner drum in the compressor rotor wheel disc connection structure.
