LI Xun1, YU Jianhua2, ZHAO Peng1
DOI: 10.16080/j.issn1671-833x.2016.21.041
Profile precision and stability of aeroengine blade has a direct influence on the global performance of
aeroengine. Because of high machining difficulty and weak stiffness, profile precision and surface quality are very hard
to meet the design requirements. So, many methods are developed and utilized to control the deformation of aeroengine
blade. Based on the analysis of deformation mechanism and application characteristics, the deformation control methods
and mechanism for machining aeroengine blade are classified. Meanwhile, different characteristics of deformation control
methods are analyzed in depth. According to the structure, difficult-to-cut material characteristic and some processing problems
of aeroengine blade, controlling the deformation caused by residual stress is the key point to reduce the profile errors
of blade to be 20μm. Moreover, the high-speed helical cantilever grinding process using the super-hard abrasive wheel is
effective in the finish machining aeroengine blade to control the integrated deformation.

Ceramic core is used to form the cooling channel of hollow turbine blade in investment casting process.
The bending and torsion deformations of ceramic core have direct influence on the wall thickness dimension accuracy of
turbine blade. To study bending and torsion deformation of ceramic core generating in manufacturing process, firstly, based
on the definition of bending and torsion deformations for airfoil and the structure characteristics of ceramic core, the algorithms
for computing bending and torsion deformations of ceramic core are studied, including contour-based methods:
Snake-model, spline-fitting method and point-based methods: Convex-hull, 2D-registration, distance-weight method. Secondly,
through computing a simulated known bending and twist deformation, these five methods are compared. The comparing
results indicate that the accuracy and stability of spline-fitting method is better than other methods.

The inevitable mistuning in aeroengine bladed disks can lead to considerable increase in vibratory amplitude
and stress, and thus deteriorate the structural integrity and reliability. Therefore, the dynamic characteristics of mistuned
bladed disks have been drawn great attention in both academic and engineering fields around the world. This paper
presents a review of the modeling and analysis methods for mistuned bladed disks, with particular emphasis on the geometric
mistuning of integrally bladed rotors and multistage bladed disks. The recent researches on mathematical representation
and reduced-order modeling of geometric mistuning are introduced. Important developments and future research directions
in this area are highlighted.

105 Advancement of Technologies for Preparing High-Performance Aluminide Coatings
SHEN Mingli, ZHU Shenglong
DOI: 10.16080/j.issn1671-833x.2016.21.105
Aluminide coatings is one key for protecting hot sections of turbine engines against high temperature oxidation
at present, which will also be an essential technique for developing advanced turbine engines in the near future. Conventional
techniques for preparation of the coatings are commonly based on chemical vapor methods, which are difficult for
obtaining high performance aluminide coatings except for low efficiency, chemical hazards release that induces air pollution
and equipment corrosion. High efficient and “green” techniques would be future trends for obtaining advanced aluminide
coatings. High efficiency has been achieved by a strategy of mechanical energy-assisted aluminizing in recent years. In
the mean time, “green” techniques have been developed by a strategy of combining physical vapor deposition and post high
temperature diffusion treatment. By combining the two strategies, high efficient and “green” aluminizing can be achieved,
using ion bombardment energy generated from ionized physical vapors in vacuum. It would be a new effective solution to
preparation of advanced aluminide coatings.
