Abstract:
Remanufacturing of damaged blades has been widely discussed in the field related with aero maintenance. Cross-section curve is the key factor for rebuilding 3D airfoil of a damaged blade. This paper focuses on how to reconstruct the cross-section curves of a tip-defective blade. The difficulty in the reconstruction of the cross-section curve is in broken region, where some data points are absent. In this paper, a method for reconstructing the cross-section curve in small-scale broken region of the blade tip is proposed. This method involves 3D noncontact digitization, methodology of obtaining

Abstract:
In turbomachinery bladed disks are typical cyclic symmetric structures where high-cycle fatigue of the blades can easily occur. Increasing the shroud structure is an effective blade vibration reduction method using the dry friction of the shroud contact surface to dissipate vibration energy. During one vibration cycle of the blade, the contact surface of the shroud may have one or several states of stick, slip, and separation due to the different amplitude of blade, which affects not only the damping, but also the stiffness of the system.

Hollow blades with honeycomb structures are increasingly used in the turbine engines for reducing weight and saving costs. The hollow blade is a typical thin-walled structural part with low stiffness, the machining system of which is often unstable and likely to chatter.

The wind power industry is one of the fastest-growing renewable energy industries in the world. Since more energy can be extracted from wind when the density is higher, a lot of the investments made in the wind power industry are made in cold climates. But with cold climates come harsh weather conditions such as icing. The icing on wind power rotor blades causes the aerodynamic properties of the blade to shift and with further ice accretion, the wind power plant can come to a standstill causing a loss of power, until the ice is melted. How big these losses are, depend greatly on site-specific

Forming the second part of a two-part paper, the estimation of damping is presented here. Part 1 discusses the experimental approach and the results on blade resonant response measurements. In the study of forced response damping is a crucial parameter which is measured to quantify the ability of a vibrating system to dissipate vibratory energy in response to a given excitation source. The blading of turbomachinery components is particularly prone to forced response excitation which is one of the major causes of high cycle fatigue failure during operation.

Abstract:
Rip-sawing following the curvature of a crooked log means advantages for yield. However, the possibility to saw in a narrow curve with a circular saw blade is limited because of the inherently flat geometry of circular saw blades. For a double arbour circular saw the situation is even more problematic because the two blades have a certain overlap and thus, the two arbours are not positioned in the same horizontal position. In this study, a theoretical geometrical study of the creation of a kerf with a single circular saw blade and with a double arbour circular saw with two saw blades was exami

Abstract:
Abstract In civil aero-engines, the shafts are supported by oil-lubricated bearings. These bearings require sufficient lubrication to provide cooling and ensure the reliability of the engine. In some engine configurations, it is not possible to supply oil to the bearings via the traditional direct jet injection method. An oil scoop delivery system is one of the solutions proposed to solve this problem by directing oil from a nozzle towards a rotating plurality of scoops that have internal conduits to direct the captured oil to an under-race location. The performance of an oil scoop can be quan

Abstract:
Curved blade has been widely used to reduce the endwall loss, but there is no criterion for curved blade design. Relationship of the optimum curved blade generate line (stack line) and the inlet Mach number, solidity, aspect ratio and camber angle in a linear compressor cascade were researched by optimization method in present paper. The stack line is vertically symmetrical, composed of two third-order Bezier curves and a straight line. The results show that total pressure loss coefficient decreases with the curved height increasing in the present calculate conditions at the same curved angle,
