Unexpected vibration of aero-engine blades may lead to fatigue failure. In order to reduce the harmful vibration of aero-engine blades, many smart materials have been employed for blade vibration suppression applications. Among them, a hot research area is vibration suppression using piezoelectric materials with damping circuits or active vibration control algorithms, by providing new and effective methodology to suppress the vibration of aero engines. This paper summarizes the current research status of vibration suppression for aero-engine blades using piezoelectric materials in recent years. Firstly, the structure of aero-engine and the background of vibration suppression are introduced briefly; secondly, the design process and several typical applications of passive vibration suppression and active vibration suppression methods are reviewed, their advantages and disadvantages are compared; finally, conclusions are made and some suggestions are summarized for the next generation smart structure aero-engine blades, such as the necessity of global geometry optimization and topology optimization, integrated structural/control optimization for engineering applications.

“…In recent years, with the rapid development of digitalization and intelligent manufacturing, various CNC forms and special processing methods have been widely used in the field of blade polishing, such as CNC precision milling [3], robotic polishing [2,6], abrasive flow polishing [1], and abrasive belt polishing [5], 5-axis CNC machining is one of the most common processing methods for integral impellers [7,8], due to its advantages of high machining adaptability and controllability of machining dimensional accuracy. Although this method can successfully process an integral impeller with the surface roughness of Ra 0.8 μm, the machining trajectory planning is complicated and the tool marks on the machining surface are obvious [9].…”

A novel process of immersion fluid chemical mechanical polishing (CMP) is proposed to replace the traditional manual polishing and the mechanical polishing for integral impeller. Using the FLUENT software to simulate the force state on the integral impeller surface and the fluid motion trajectory during the polishing process, in order to determine the optimal polishing process , and to reveal the formation mechanism of the high-quality integral impeller surface. The immersion fluid CMP process experiment was carried out on the integral impeller with the developed CMP slurry containing phosphoric acid (H3PO4), hydrogen peroxide (H2O2), citric acid (CA), silicon carbide (SiC) and deionized water. After 2.5 hours of CMP, the surface roughness decreased from Ra 1.651 μm to Ra 0.658 μm, the polished surface is smooth and without tool marks. X-ray photoelectron spectroscopy (XPS) and infrared (IR) were used to reveal the polishing mechanism of the oxidation, dissolution, removal and complex precipitates on the surface of the integral impeller. This research provides a novel process for the precision machining of other complex structural parts similar to the integral impeller, which has the characteristics of simple polishing process, high efficiency and good polishing effect.

“…In the working process, the parts with multi-curvature complex surface boundaries have more advantages in guiding fluid, heat transfer, wave-transmitting, and part accuracy retention than the single curvature surface boundary 1 . For example, the aero-engine blade is designed as a curved surface with torsional angles, which can improve the blade stability in the process of high-speed rotation (the rotation speed of high-pressure blades is more than 10000r/min) 2 . At the same time, the engine cooling efficiency can be improved by adding condensation holes on the blades, thus increasing the thrust-toweight ratio of the engine 3 .…”

With the rapid development of advanced manufacturing technology, the market demand for high-precision functional curved surface parts is increasing. The traditional processing technology has shortcomings in the precision forming of curved parts, especially in the processing of functional and fine structures. Laser processing has the characteristics of non-contact, high precision, and controllable energy, which makes it have special advantages in machining highperformance surfaces. This paper analyzed the application requirements of high-precision complex surface processing and the differences between traditional surface processing methods and curved surface laser processing. A five-axis CNC laser processing technology for curved surfaces was proposed. At the same time, the digital modeling and laser machining simulation verification of a typical curved surface part were carried out by using this processing technology. The result proves the effectiveness of the digital processing flow of curved surface laser machining and provides a digital solution for laser machining of high-precision and complex curved surfaces.
