In an embodiment, cooling holes are provided in each platform to cool distressed locations in the platform and improve the durability of each turbine blade.NNAWUIHE ASONYE OKPARAAARON J. DICKDONALD JOSEPH BOGNATZMARIUS DUMITRASCUESTEVAN DANIEL NEGRETE...
A cooling hole is important structure of turbine blades for high-performance aircraft engines. It is very challenging to manufacture cooling holes in superalloys including nickel-based and titanium alloys. This article aims to provide a critical assessment on the major types of machining processes for...
For turbine cooling structures, the number of holes and their location within the blade are standard controls that turbine engineers need: Vary the number of holes for the turbine blade cooling The variation of the holes’ diameters is shown in this last animation and can be also controlled by...
Cooling air flows from an inside of the insert core towards the chambers through the impingement holes, and the blade body is provided with a plurality of film cooling holes each penetrating the blade body from the chambers to an outer atmosphere side of the blade body and extending in a ...
Turbine blade cooling In the turbine section, the blades are installed directly behind the vanes and therefore experience slightly lower temperatures. Being exposed to high operating temperatures, gas turbine blades benefit from a number of cooling methods and associated critical features. These are expl...
Heat transfer enhancement within a turbine blade cooling passage using ribs and combinations of ribs with film cooling holes A transient heat transfer method using liquid crystals has been applied to a scale model of a turbine rotor blade passage. Detailed contours of local heat ... JR Shen,Z ...
