Journal of Fluids Engineering, 1940
Abstract This paper reviews the blading-design practice associated with modern high-pressure high-temperature steam turbines. The design problems encountered in the development of partial-admission impulse blading for topping units are described, as well as the current engineering practice employed in the manufacture of such blading.

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.

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. RENEWABLE ENERGY FOCUS' KARI LARSEN INVESTIGATES POSSIBLE ROUTES FOR THE RECYCLING OF WIND

For a reduction of blade vibration amplitudes in airborne gas turbines special damper devices are used which usually are arranged between the blade platforms of neigboring blades. These dampers possess a cross section like a parabola or a circle and are formed out of sheet steel.

Turbine blade vibration dampening
The Journal of the Acoustical Society of America, 1998The present turbine wheel assembly increases component life and turbine engine longevity. The combination of the strap and the opening combined with the preestablished area of the outer surface of the opening and the preestablished area of the outer circumferential surface of the strap and the friction between the strap and the opening increases the ...

Titanium Steam Turbine Blading
1990The use of titanium alloys for the long last stage and L-1 stage of low-pressure steam turbines has been in development for over 30 years, and appears to be entering commercial use. The titanium blades are used in the steam transition L-1 row, because they are immune to pitting corrosion by the corrosive early condensates at the Wilson line.

Abstract Three blades from 45,000 kW, 3,000 rpm turbine were received for examination, comprising the root of blade 28, blade 89 showing a crack in one of the root teeth, and blade 106 which was free from defects. Microscopic examination of the blade material showed it to be a ferritic stainless steel of the type commonly used for ...
