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

This application belongs to the technical field of connection design of compressor rotor discs, and specifically relates to a connection structure of compressor rotor discs, including: a front-stage rotor disc; a rear-stage rotor disc adjacent to the front-stage rotor disc; an outer drum The cylinder is set between the front-stage rotor disk and the rear-stage rotor disk, one end is connected to the front-stage rotor disk, and the other end is connected to the rear-stage rotor disk; the inner drum is located inside the outer drum, and one end is connected to the rear-stage rotor disk. The front-stage rotor disc is connected, and the other end is connected with the rear-stage rotor disc. In addition, it relates to a drum structure, including the outer drum and the inner drum in the above-mentioned connection structure of the compressor rotor disk.

Description

technical field [0001] The application belongs to the technical field of connection design of compressor rotor discs, and in particular relates to a drum structure and a compressor rotor disc connection structure thereof. Background technique [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, 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. [0003] In view of the existence of above-mentioned technical defect, propose this application. [0004] It should be noted that the disclosure of the above back...
