Manufacturing of a Turbine Blade
It shows detailed stages, starting from the initial stages of design to material selection, then to casting, forging, and CNC machining up to final assembly with strict quality control. It emphasizes precision engineering for that great performance durability.Dr. Naveen Krishna Alla +3 more

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. The

Parallel Computation of Turbine Blade Clocking
International Journal of Turbo and Jet Engines, 1998This paper presents a numerical study of airfoil clocking of a six-row test turbine configuration with equal pitches. Since the rotor-stator interaction flow is highly unsteady, the numerical simulation of airfoil clocking requires the use of time marching methods, which can be computationally expensive.

A framework for isogeometric‐analysis‐based optimization of wind turbine blade structures
Wind Energy, 2018Early-stage wind turbine blade design usually relies heavily on low-fidelity structural models; high-fidelity, finite-element-based structural analyses are reserved for later design stages becauseoftheircomplexworkflowsandhighcomputationalexpense ...

The Impact of Blade-to-Blade Flow Variability on Turbine Blade Cooling Performance
40th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2004The focus of this paper is the impact of manufacturing variability on turbine blade cooling flow and, subsequently, its impact on oxidation life. A simplified flow network model of the cooling air supply system and a row of blades is proposed. Using this simplified model, the controlling parameters which affect the distribution of cooling flow in a ...

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.

Control of separation flows of turbine-blade-tip turbines by splitter blades
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and EnergyGas turbines cannot be directly reversed, and the astern operation of gas turbines still requires additional power transmission equipment to be achieved. To compensate for this deficiency, the application of turbine-blade-tip turbine in gas turbines was proposed.

Turbine Size and Temperature Dependence of Icing on Wind Turbine Blades
Wind Engineering, 2010The dependence of atmospheric icing on temperature and wind turbine size was studied by performing numerical simulations of ice accumulation on five different wind turbine blade profiles at four different temperatures. The profiles were for 450 kW, 600 kW, 1 MW, 2 MW and 5 MW wind turbines, and the temperatures −10°C, −7.5°C, −5°C and −2.5°C.
