For revolving components like compressor stages in aero-engine, it is critical to ensure that
the overall concentric performance of the assembly is extremely excellent to satisfy the …

Aero-engine rotors are mostly manufactured as an assembly of individual parts to keep
manufacturability and maintainability. Assembly deviations are unavoidable because of …

The measurement and assembly of the aero-engine rotor are separated from each other,
which makes it difficult to keep the assembly datum consistent with the measurement datum; …

Purpose–This paper aims to provide an assembly method to improve cylindrical
components assembly quality. The proposed method not only could be applied to tolerance …

The coaxiality and unbalance are the two important indexes to evaluate the assembly quality
of an aeroengine. It often needs to be tested and disassembled repeatedly to meet the …

In rotating machinery with a multi-stage assembled rotor, such as is found in aero engines,
any unbalance present will undergo unknown changes at each stage when rotating the …

For the assembly of a multi-stage rotor, such as an aero-engine or gas turbine, the parts
need to be assembled optimally to avoid excessive unbalance. We propose a method to …

This paper presents a novel optimization technique in straight-build assembly to control
variation propagation. The optimization technique is developed by minimizing the …

An aero engine fan rotor is composed of a multi-stage disk and multi-stage blades.
Excessive unbalance of the aero engine fan rotor after assembly is the main cause of aero …

The assembly quality of the multistage rotor is an essential factor affecting its vibration level.
The existing optimization methods for the assembly angles of the rotors at each stage can …
