Titanium for Steam Turbine Blades

JOM, 1982
Titanium is currently being considered as a blading material in large, power-generating steam turbines. The high strength-to-weight ratio of titanium and its excellent corrosion resistance make it an ideal candidate for turbine blading. The advantages of using titanium include increased turbine size, improved efficiency, and increased corrosion ...

The Vibrations of Laced Turbine Blades

The Journal of the Royal Aeronautical Society, 1957
While the use of blade lacing wires or shrouding is not altogether common in gas turbine practice, occasions may arise when their use is desirable, and the purpose of this note is t o present a method whereby the vibrational characteristics of a number of blades wired together may be conveniently found.

Composite gas-turbine blades

Russian Engineering Research, 2016
Theoretical analysis of composite blades for gas-turbine engines is based on the theory of effective moduli and the Lagrange equations. The blades are regarded as twisted rods; the flexure-approximation coefficients are adopted as generalized coordinates.

Improvements in Turbine-Blade Manufacture

Russian Engineering Research, 2018
A completely automated manufacturing technology for turbine blades is proposed. The system includes automatic loading and unloading of the workpiece; its automated orientation in the coordinate system of a multifunctional grinding center; and automated geometric monitoring of the components by means of a coordinate-measurement center.

Recycling wind turbine blades

Renewable Energy Focus, 2009
WITH A BOOMING WIND ENERGY INDUSTRY, DRIVING THE DEVELOPMENT OF LARGER AND LARGER TURBINES, THE QUESTION IS NOW ARISING OF HOW TO DEAL WITH WIND TURBINES AT THE END OF THEIR LIFECYCLE, AND PARTICULARLY THOSE WIND TURBINE BLADES MADE OF HARD-TO-RECYCLE COMPOSITES.

Failure Analysis of Turbine Blades

1993
Abstract Two 20 MW turbines suffered damage to second-stage blades prematurely. The alloy was determined to be a precipitation-hardening nickel-base superalloy comparable to Udimet 500, Udimet 710, or Rene 77. Typical protective coatings were not found.

Failure in Steam Turbine Blades

2019
Abstract When a steam turbine was put out of service, cracks were noticed on many of the blades in the low pressure section round the stabilization bolts and perpendicular to the blade axis. The blades were made from chrome alloy steel X20-Cr13 (Material No. 1.402).
