Turbine Blade Cooling: The Blade Temperature Distribution
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2006Air cooling of high-temperature gas turbines is a standard practice; the air first cools the blading by internal convection and then by external film cooling, after ejection through holes and slots in the blade surface. In some ‘conventional’ analyses of turbine blade cooling, a ‘standard blade’ is invoked, which has a uniform blade temperature equal ...

Abstract In an electric power station, seven turbine blades out of 112 broke or cracked within 8 to 14 months after commencement of operation. The blades in question were all located on the last running wheel in the low pressure section of a 35,000 kW high pressure condensing turbine.

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. The

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.
