Question

How to remove the turbine blades mounted on the rotating disk? Turbine blades single crystal

Turbine blades, how to remove this blade?

Answer 1

When it is necessary to remove the turbine blades from the turbine disc, the adjacent turbine blades are restrained by each other, making it impossible to simply remove the turbine blades from the turbine disk.

Turbine blade removal tools and methods and processes

In some related technologies, the operator first loosens the turbine blade through a tool such as a hammer, and uses the gap to lift a turbine blade, at which point a new gap is formed on the side.

The operator then lifts a turbine blade on the side and operates sequentially until the cumulative gap is sufficient, the corresponding blade can be taken out, and the adjacent blades no longer restrict each other, and the entire circle of blades can be removed in turn.

Answer 2

A single crystal leaf means that there is only one crystal nucleus on the entire leaf, and other iron atoms are attached to this crystal nucleus in turn. In this arrangement order, the force between the atoms is very large, and the allowable tensile stress is also very large, which can meet the blade requirements of the new large thrust engine.

Answer 3

When the turbine blade is working, it needs to have a high adaptability to sudden temperature changes, and it must also have the ability to face the strong braking force at start-up, and under high-speed movement, the blade needs to withstand huge centrifugal force and root shear stress.

This working environment requires the material of the blade to have high creep strength, vulcanization corrosion resistance, etc., and some advanced aero engines may have more requirements.

Answer 4

The turbine blades in the turbine engine are the most important components of the engine, and the turbine blades are located in the area with the worst working environment, the highest temperature and the most complex stress conditions of the entire engine, so the quality of the turbine blades is also an important indicator to measure the field of aviation manufacturing in a country.
